    With this Bluetooth headphone, you cannot use it to watch any video since there is always 1 second lag. The charging case is not a good design as well.

    These headphones are absolutely not worth the money. The Bluetooth connection constantly falters and it's extremely frustrating trying to use them. Battery life is subpar. On top of an outrageous price point, their dysfunction is insult to injury.

    Sony got it wrong with these...

    CoreyD13

    I'm terribly frustrated with these in-ear 'bluetooth/wireless' headphones. They lose connection more oft than not, firmware update won't complete, as it fails after reaching 50%. I had a pair of Jabra Elite Sports that I was looking to replace after one of the earbuds went bad. Unfortunately Best Buy didn't have any Jabras at the store, so I decided to give these a try. The worst mistake, EVER. These are going back, after work and I'll be ordering the Jabra Elite Sports. I'll just have to wait for it to ship/arrive. Try again Sony!!!

    Really Comfortable Truly Wireless Earbuds

    Posted

    These Sony Bluetooth earbuds really surprised me with how well they fit into the ears, and from the looks of these earbuds, I was not expecting them to fit so perfectly in the ears, the design is so simple yet functional. These earbuds are inserted into the ears pointing downwards, and then a simple turn forward locks the earbuds into the ear with surprising stability and comfort. I can wear these Sony earbuds for many hours with little to no ear area discomfort at all. Most other brands of earbuds start to cause ear area discomfort when attempting to wear them for several hours. The micro USB charging cable supplied is a little longer than 20 inches, which is just the right size to make it easy to carry and yet not too short so that it makes charging placement limited, most other earbuds on the market that I have seen come with a 12 or 13 inch charging cable, and that is not quite long enough in my opinion. These Sony earbuds come with many eartip options of various sizes, there are 3 sets of foam ear tips, there is another set of 3 silicone eartips, and then there is another silicone eartip set that is installed on each earbud out of the box. In addition to the earbuds, there are 2 sets of the silicone wings that is what slides behind a part of the ear and holds the earbuds securely in the ear. The Sony app for Android has the most common functionality, the app does have an equalizer with a few presets to choose from, as of now there is no ability to adjust the equalizer manually, but the equalizer presets are sufficient. I am sure Sony will likely add the ability to manually adjust the equalizer settings with a future update of the Sony app. These Sony Earbuds do have the option of using the higher quality AAC audio codec, and the app also allows the user to set the audio to a lower audio quality setting. The lower audio quality setting is supposed to be for enhanced Bluetooth connectivity. If the audio starts skipping when listening to the higher audio quality setting, the app says to switch the audio quality to the lower audio quality setting. These Sony earbuds have great Bluetooth connectivity when connected to my smartphone, but I did experience some audio skipping when paired with my desktop. I finally realized this audio skipping was at least partially caused by the other Bluetooth computer accessories that were also connected to my desktop computer. Too many devices with a Bluetooth signal in a small area can cause Bluetooth connectivity problems. When I experienced the audio skipping, I turned off my Bluetooth mouse and keyboard and then the audio skipping stopped. The button on the right earbud is for the play/pause functionality if it is pressed once, and if it is pressed twice it skips to the next audio track, and then if a phone call is incoming, the right earbud's button will answer the call with a single press, and then another single press will hang up the phone call. Most earbud brands allow the adding of new or improved functionality when the app is updated, and I hope Sony will improve the functionality of the button on the left earbud, as at the moment the button on the left earbud is designated to toggling between the following settings: Noise cancelling, Ambient room sound, and lastly the Off setting. I have had my Sony earbuds set to the Off setting, and because of this being my chosen option, it would be better if Sony could add the toggling of these three settings to be adjusted by only the Sony app, then the left earbud's button could be assigned to an audio playback functionality, such as: Previous track functionality. I have two other pairs of Bluetooth earbuds, one is also a pair of truly wireless earbuds, and the other pair of earbuds has a wire connecting the earbuds. This pair of Sony Bluetooth truly wireless earbuds is my favorite, and this is because of the unrivaled ear comfort when wearing the Sony earbuds. I am rating these Sony earbuds at 4.5 out of 5 stars, and I would suggest these Sony earbuds to anyone who wants to have a set of Bluetooth earbuds that sound great, and are guaranteed to fit very comfortably in the ears.

    Solid Choice

    For true wireless earbuds, these are a great choice. They are on the smaller side and come with a range of sizes of in-ear cups that allow for a good fit. They sound great, but don't expect the "ambient sound" option to work as well as Sony's top line wireless headphones (which I also own). The noise cancelling is also not as good as the headphones. I've gotten three full charges out of a fully charged case, which is also on the smaller size. The battery life on the actual earbuds is okay, but not great. Maybe three hours of continual listening. I keep the case charged and just pop the buds in while I'm not using them and I've had no issues. The only downside is the Bluetooth range. I've gotten intermittent cutouts with my phone in my back pocket. Front pocket no problem, go figure. All in all a solid Choice, definitely more comfortable than the Bose options of similar cost.

    I just got mine this week end will be returning them as they are useless for my needs. Pro's They sound great and are designed great. Con's I've always loved Sony head phones in general and the Bluetooth one in particular. I've owned the MW600, the SBH50, the WH-1000XM2 They all had the unique function of pairing with two devices. I loved that about Sony, they are the only company innovative enough to do this. Not Beats, Not JBL, or Bose, but Sony. I loved the fact I can listen to my iPad for music and answer my phone when it rings These don't do that, in fact they don't do much. I can't advance to another song, replay or change the volume. I bought them for the hands free functionality and they don't do that either. It's a high price Bluetooth I've paired with my phone to drive and avoid getting a ticket. They should be waterproofed or rated, the cheaper models are but these are not. Sony please redesign these with above mentioned functions and I will sign your praises. These were a miss.

    Great Sony Sound/Design, Mediocre Battery

    Posted
    inspectorgadget

    I waited for the WF1000X to go on sale as I would never pay more than 180 for bluetooth no matter the quality (until battery life improves by 25%). I initially got the JayBird Freedom LE but they would not hold a charge so I returned it for these earbuds despite the many warnings. After a week of use, I am generally pleased with the sound quality and the design, but I don't feel they justify the $200 price tag for the following reasons: 1. Battery Life: Sony is generally known for producing batteries with high endurance, but I understand with the BT and noise-cancelling, the technical limitations will prevail and cause the individual buds to use a lot of power. Hopefully, by the next iteration of this superbly designed model, battery life will have substantially increased. On the bright side, the case is compact and charges rapidly. The buds lasted for approximately 3 hours before turning off, but placing them back into the case for 15 minutes boosted the batteries for another 1 hour and 20 minutes or so, which is nice. 2. Bluetooth Connection: When I first used the earbuds, pairing was not working but after a few minutes, the units paired with my Edge S7 without incident. There is also an NFC pairing option, but I have not used it as BT worked fine. On first listen, the right bud dropped out but I switched the settings via the app and it worked nicely. I also updated the firmware to its current version and that greatly improved connection -- to date, I have not experienced loss of connection even in areas of high traffic including outdoors in New York City. 3. Codec Issues / Video Lag: This is probably a deal breaker for some users. I initially was going to return the earbuds, but after switching the settings to "Priority on Sound Quality", the lag decreased a bit and is bearable. I hope that Sony engineers can figure out a way to resolve this issue. If it is a hardware issue in subsequent models and can't be resolved by a software update, I will probably never use wireless earbuds ever. The sound quality is very, very good and was the only quality of this otherwise well-designed product that redeemed it from being returned. Other minor issues are the fact that there is no volume control on the buds themselves, and also the blue lights blinking can be quite annoying, but this goes for all BT devices -- there should be a way to turn the blinking lights off or reduce the pulse to once every few minutes or even a low-light option. Especially in low light conditions (such as public transportation during the late evenings) or in bed at home, the blinking blue lights are very distracting. Overall, I recommend only getting the Sony WF1000X if they are on sale or if you can obtain a discount. Ideally, this particular model will retail for $150 (or less) unless the above issues can all be resolved. I got mine after seeing last week's sale ($179.99). I truly love the design of the earbuds (please stick to this form factor! @@@@@@@ and charging case and sound quality, but hope Sony can find a way to improve on its shortcomings in the future.

    While the audiophiles out there may scoff at the mere existence of a small, highly mobile, wireless earbud that requires a special case just to charge it, there's no denying that truly wireless earbuds are becoming more and more popular with each passing month. No, Apple wasn't the first to do it, not even the first to do it well, but man oh man did they do it well. And, we've seen the typical post-Apple-success market spike with truly wireless earbuds over the last several months, with more and more players coming into the space. There is a natural tendency to harshly judge the first players to a space, namely Apple, which (regardless of how you truly feel about them) have been able to really drive the accessories market forward as a result of their products. Truly wireless earbuds are no different, as Apple (with their AirPods) have been wildly successful since release in a market that had previously seen novelty exposure at best. More frequently than on store shelves, another Kickstarter campaign for another truly wireless bud that was another of the first of its kind would find its way to your Facebook timeline-but alas, those products were months (or years) away if they ever hit market at all. The AirPods spent their first several weeks after release with limited or no availability, and since then audio manufacturers have been working on perfecting their own versions. Enter Sony's WF-1000X earbuds. My very first pair of over-ear headphones were Sony-branded, and I've always had a soft spot in my heart for their products. More recently, I was disappointed when purchasing one of their small Bluetooth speakers, but nonetheless was excited about the WF 1000X's and the Sense Engine technology that would allow me to adjust the noise canceling based upon my environment (as a side note-Bose's ANC technology was a bit too much for me and made me motion-sick, so adjustable noise cancelation is a big deal for me). Upon opening the Sony buds, the first thing I noticed was a lack of a premium packaging experience. But, at a price of $200-I expect a box that you're more likely to keep than one you won't mind throwing away. Nonetheless, the buds themselves are packed separate from the small charging case, and come with a variety of tips and a couple different sizes of fins to help with the ideal fit. And speaking of fit-let's talk about how Bose's earbuds are the best (in my opinion) in terms of fit across the entire market of earbuds right now. I've tried dozens of manufacturers and products, and no one has really been able to consistently deliver what Bose does in terms of earbud fit-both from a security and noise isolation perspective. And, at first glance, Sony's buds weren't going to change my opinion; they came with two sets of add on fins that didn't seem to be large enough for folks with bigger ears. The buds themselves are designed to fit snugly into the ear canal, but I always tend to have problems with wearing buds of that style for long periods without having to readjust them every couple minutes. But, miraculously, Sony has put out the first (ever) fin that really holds this style bud in my ear. Serious kudos to Sony for developing such a simple tool for the job (it's worth noting here that the fin is entirely optional, and if you have no issue at all with ear-canal style buds, I would expect these to be no different). Something else that's important here, perhaps even more important than the sound quality, is the Bluetooth performance, as there are no "wired" options for these buds. This, for me, was the biggest area of disappointment with Sony's buds, as the onboard software doesn't seem to be advanced enough to prevent the Bluetooth audio/video lag that we all remember from 3 or 4 years ago. As far as music-only performance is concerned, Bluetooth performed well without any skips, but as soon as I pulled up a YouTube or Netflix video, the lag was too much to bear and I had to switch to another set of headphones...and that very well could be a deal breaker for many buyers. Next, on to Sony's Sense Engine technology, which is supposed to be a great new way to customize your noise cancelling experience. Most noise-canceling headphones being released right now have some sort of adjustability to ANC, and the implementation with the WF-1000X's is acceptable, but certainly not revolutionary, nor is it anything that sets them apart from the competition. Again, when it comes to ANC, Bose is the leader and that hasn't changed. Honestly, with the fit being as good as it's, the noise isolation alone is adequate for some basic noise canceling, and honestly the ambient noise "bleeding" settings just pump more hissing into your ears than anything else. Another key performance indicator for a good set of truly wireless earbuds is the battery life. Keeping in mind that sound settings (like a more bassy xperience, or higher volumes) will impact battery life significantly, I was less than pleased with the battery life of the WF-1000X's. Battery technology is hopefully on the brink of a major paradigm shift, but until that shift happens small earbuds will never house batteries large enough to give them great battery life. It is for that reason that manufacturers are including charging cases, which both help prevent loss as well as add some extra battery life. The buds themselves are advertised to push 3 hours of playback on a charge, and through my testing this is a pretty accurate number. The case, when fully topped off, should charge the buds completely twice-taking your listening time to around 8-9 hours total with some time in between charging. And then there's sound. Holy cow, the sound. I consider myself a wannabe audiophile-the kind of person that plays really close attention to the variations in headphones and earbuds, but doesn't own a DAC and tends not to play with mixers. That said, the sound profile on these Sony WF-1000X buds is probably what I would consider the ideal profile for me: exaggerated bass (although not too much) with clear lows and less preference on quality in the highs. I found the low to be impressive considering the size of the drivers, the mids to be ideal for most users, and the highs to be less important than the other two but still clean enough so as not to be a distraction when listening. And, if you don't like the particular profile that these have out of the box, you can download Sony's Headphones app which allows for some preset mixer configurations that are remembered on your buds even if you change between devices (phone, tablet or laptop). The app hasn't yet been ported for the iPad's screen size or orientation, but I can get past that. Another quick note; I did test a couple of calls with these in my ears and found that the other parties could hear me clearly without much background noise, even though I was outdoors on a windy day. In my opinion this is not a reason to buy these, necessarily, but definitely a value-add that you can take a call while you're on the move without having to worry about whether or not the caller can hear you. So the verdict is simple...if you're doing shorter listening sessions that don't require video synchronization, and you don't need much by way of noise cancelation, but you still like a slightly heavier sound profile and want to go fully wireless-these should be right at the top of your list. Hands down, the sound quality on these obliterate Apple's AirPods, for what that's worth. If, however, you're looking for earbuds that you can use to listen to music AND watch movies, without additional software you may be frustrated in not being able to synchronize audio and video. In theory, this can be patched with firmware updates, but nonetheless something to be aware of. All in all, for the price, these are a good addition to my collection, albeit a little disappointing that I can't consistently use them for anything other than music and phone calls (yet).

    These are some really nice looking and feeling ear bubs. The sound quality is nice and once you've downloaded the Sony I Headphones Connect App the doors are open to many different possibilities. Depending on where you're, you can adjust the sound and cancel out many of the background noises, I don't recommend this if you're driving. @@@@@@@@ Unless you're using them for phone calls, then you're only using the one left ear bud. @@@@@@@ Which brings me to the main ear bud being the left one. I'm so used to the right side being the primary function ear piece. I'll live. Then we get into the connection. It's a total pain getting started The NFC only works on certain devices ( Apple products mostly) so if you're using an Android device, you will have to pair with the Bluetooth style of pairing. I had a time connecting these, mainly because of the button placement. The charging is hit or miss due the way the cradle is set up. You have to snap the ear buds in place. On other ear buds I've used, they generally just sit in the cradle and start charging. So I charged them to what I thought was full, but it turns out they weren't connected to the cradle properly so they never actually charged. This left me without Bluetooth use. The next issue I've is that I work out and I rely on my Bluetooth to give me that soundtrack to get my grind in. These ear buds are not for gym rats as they can't get very damp. So sweat is not an option. Coffee houses and events where you're a spectator is predominately what these are used for. I can't recommend these to anyone who are active, which is basically what Bluetooth ear buds are good for. And at the price range, I can't justify the purchase. If you've the money and want a pair nice( comfortable ) casual Bluetooth ear buds, that look and feel really nice. And you already have a pair of dedicated ear buds for when you're active, By all means, grab you up a set. Other than that, steer clear of these. Better luck next time.

    Wireless is the New Freedom

    The setup for the Sony 1000X Wireless Noise-Canceling Headphones can be a tiny bit confusing. However, a nice picture diagram is included to help facilitate the process. After you have taken out the pair of headphones, you need to insert them into the case for them to power on. The case works like a portable battery for the headphones and a carrying case at the same time. They will power on and will be discoverable in your mobile device. I tested these on an iPhone and the phone recognized that the Sony Headphones App needed to be downloaded for proper installation. I proceeded to do so after it prompted me to. The key feature of these headphones is that they are truly wireless. There is no connecting wires between the two ear pods. This makes them ideal for working out without having to worry about accidentally pulling on a wire. I wore them while jogging, doing household chores, and walking about without them falling off once. The noise canceling feature work fine, though not the best I've used. I was able to use things like a blender and a vacuum cleaner without disturbing my music. I could, however, hear my voice. You have the option to optimize the noise canceling features in the app that you download. The performance of these headphones are great. They are stereo headphones, so you won't hear the deeper bases produced by headphones that fully cover the ear for a similar price, but the convenience of not having something heavy on your ears is worth it. Bass and deep sounds still sound great. This is especially true when you turn on the noise canceling feature that eliminate most ambient sound around you, helping you focus and immerse deeper in your entertainment of choice. The headphones meets my expectations. I did encounter a common problem amongst bluetooth headphones and mobile gaming. There seems to be a delay in audio when playing video games on your mobile device. I tested this with Clash Royale and with Geometry Dash, the latter which is crucial for there to be no delay in audio to be successful. For that reason, I deduct one star. This problem doesn't exist when listening to music or watching your favorite streaming show from popular streaming services. If mobile gaming isn't your scene, then these are a great pair of headphones. The price for Sony 1000X headphones in terms of value may look steep at first, but you must use them to believe how good they sound and how convenient their size and wire-free status can be. Keep in mind that included in the package is a portable rechargable battery for the headphones that doubles up as a carrying case. There are also plenty of options for various sizes of ear holes. I highly recommend this product for people who are tired of having wires in the face or arms while exercising or doing household chores. If you like listening to music or watching TV shows while on a bed, there won't be much of a hindrance or discomfort, thanks to the unique design and smallness of it. These headphones pack a lot of power in a tiny package.

    Truly wireless Bluetooth earphones

    Setup: Start-up instructions were pictorial and a bit cryptic. A few words would have been nice (e.g. NFC connection instructions are on the second page and could have been used in place of the Bluetooth setup instructions on the first page). Nonetheless, I followed the instructions from step 1 and encountered no problems. Instructions suggested charging in carrying case for 1.5h. I did not try to use/pair them out of the box. The left earpiece went directly into pairing mode when removed from the case and was easily paired with my Bluetooth source (Samsung S4 Active). The right earpiece automatically connected to the left one when it was removed from the charging case. I had some difficulty getting any sound from the Neutron music app and had to resort to the native Android music player. However, after switching to and then removing my favorite wired in-ear-monitors (IEMs), Neutron seemed happy to send output to the WF-1000X. This was likely a configuration issue with Neutron and not a problem with the Sony headset. Sony Headphones Connection App: While I rarely recommend installing the app accompanying most headphones, the Sony Headphone Connection (SHC) app is an exception. The SHC app allows you customize the noise-cancelling (NC) features for the WF-1000X. On Android, the app needs the following permissions: . GPS and network location information . Read/Modify/Delete contents on SD card . Full network access and view network connections . Access Bluetooth settings and pair Bluetooth devices . Prevent phone from sleeping The app will send some personally identified information back to Sony. You can opt out for some items by going to the online privacy statement (accessed through the EULA). Location information is used by the adaptive location-dependent NC feature. The app also includes some (relatively useless) equalization (EQ) presets which cannot be modified and, in my opinion, diminish the overall sound quality (SQ) without an accompanying increase in volume. I could not find a way to customize any of the EQ settings to my personal preferences. "Off" is the best EQ setting IMHO. The app also allows you to select from two Bluetooth communication protocols ("Priority to Sound Quality" [A2PD] and "Priority to Stable Connection" [SBC]). If the sound is intermittent in the right earphone (or both earphones), as it was for me in my office environment with lots of 2.4GHz interverence, you will need to select the "Priority to Stable Connection" option and be content with the lower complexity codec [see https://en.wikipedia.org/wiki/SBC_(codec)]. It's not that bad and reduces the drop-outs in environments with high 2.4GHz interference. NC is OK, but isolation seems to have the biggest impact on muting external sounds. I have not tested the adaptive (i.e. location-dependent) NC feature. Comfort: The earphones are relatively large, but fit comfortably and snuggly (for me) with the medium tips and smaller "wings". The ear tips provide some isolation, but, while Sony refers to the design as "closed dynamic", there is no back-suction on removal. The only "discomfort" for me is the occasional annoying click when changing apps and low-frequency noise when NC over-corrects. Bluetooth: Bluetooth range is adequate for most purposes, at least 30 feet in "line-of-sight" or less depending on physical obstacles. For environments with high 2.4GHz interference, I recommend the "Priority on Stable Connection" option in the HPC app. Microphone & remote control: From what friends and colleagues tell me, the microphone works well with good voice quality and no feedback. Audio for phone calls comes only from the left earphone. Both earphones contain a microphone for NC, but only the left functions during telephone calls. A small button on the right earphone allows you to accept incoming calls and disconnects calls when you are done. To my knowledge, there is no button to pause/play or forward/back functionality. Battery: The downfall of many Bluetooth devices, battery life. Doubly so when playing music and processing external noise for active NC. The WF-1000X "solves" this problem with a nifty carrying case that charges the earpieces when not in use. Sony claims 9hr of battery life, but, with NC enabled, the earpieces will only go for 3hr of continuous listing without recharging in the case. Battery life will depend a lot on usage (NC vs no NC; standby vs active listening, etc.). Don't expect to use them continuously on a transcontinental flight. Sound Quality: Were it not for the Bluetooth connection, these would near-audiophile quality IEMs. The sound signature is surprisingly flat. Instrument separation and sound stage are good. Treble and mids are well-reproduced. Bass is forward, but a bit muddy compared to a reference-quality wired balanced armature IEM and headphones (think Etymotic ER4SR and Sennheiser HD600, respectively). System sounds (i.e. button push tones, app change "clicks", etc.) can be annoying and changes in the output mode using the HPC app can pause playback. The closed design is a blessing and a curse. The blessing, you can't hear what is going on around you. The curse, you can't hear what is going on around you. The adaptive and user-selectable NC behavior is a help here.
