      Long Battery, Comfort, and Good Quality

      I bought these headphones from Best Buy just over a week ago. I was looking for something that would produce decent sound without getting into the higher end, $200, headphones. My overall thoughts are that these are a great purchase for under $150. I will say, you're not going to get a big bass kick from these. If you're looking for a lot of heavy bass, then these are not the headphones for you. You will be disappointed by the bass if that is what you want. However, if you're looking for more of a genuine, crisp sound without spending over $150, then these are what I recommend. Pros: They have good battery life. I have used them all day and did not get any drop in performance from low battery, nor did I ever run out. You can tell that these are built with the Sennhesier quality, but they are still light weight. I personally think these have a better build quality than most Beats, or Sony headphones. If you're listening on a computer, these things can get LOUD. I have noticed however, that they are not as loud when used with a phone, but that was expected. The ability for both Bluetooth or corded experience is a must in over-the-ear headphones now, and Sennhesier delivers on that. The controls on these headphones are great. I come from most of my experience with controls being on in-ear headphones, so it was awesome to have an upgrade in control quality. Phone calls on the HD 4.40 are actually pretty great. I spent some time on the phone with some people, and it felt like they were in the room with me. The general consensus from the other side of the call was that the audio was fine. I think that they're comfortable, and I have big ears. I have such big ears that they don't quite fit over my entire ear, but they mostly do, and I still found them comfortable. I was able to wear them hours on end. Cons The Bluetooth, while good quality with no lag, lacks volume. That's pretty typical with headphones though. They are not noise canceling. This came as a suprise to me, because I assumed that any over-the-ear headphone over $100 should be noise canceling. These are not. I was pretty disappointed when I could still hear the meat-head at the gym grunting away, but I should have read the box first. Maybe it's my fault for not checking, but noise canceling should be a given at this price. Lack of bass. They're not hard hitters, which usually doesn't bother me, but it's lacking enough that I have to mention it. Final Thoughts: I bought these headphones for the purpose of going to the gym. With that said, they do the job and they don't break the bank doing it. I found their long battery life, comfort, and build quality to be worth the $150.00. I would recommend buying them if you're looking for an economy over-the-ear headphone. I will say however, that the carrying bag that comes with the headphones is too big. Headphones are more secure in a tighter bag, so I replaced mine. I would still have no worries about throwing these in a backpack without the carrying bag, which I did one day. They lived.

      Five stars in sound and battery, not much else

      A few weeks before purchasing these headphones, I purchased Beats Studio Wireless 2.0. In comparing the two, the Sennheisers win in sound quality by a mile! For me, that is the most important factor, so I'm pretty happy with these. The Beats had some other advantages though. The beats had active noise cancelling. These are passive. And, when my kids are running around, it definitely interferes with the Sennheiser's more. But, the Beats noise cancelling was part of what impacted the sound quality that set. The HD 4.40 has a much clearer tone, and is well balanced from the low end through the mids to the highs. The entire range is striking and really brings out sounds in the music I haven't heard with any other headphones I've had. Both the Sennheiser and the Beats don't have enough padding on the top bar, and as other reviewers have noted, become irritating over time. The battery life on both headphones are outstanding. Well over 20 hours for both. The build quality and packaging quality of the Beats headphones were better than the Sennheisers. The Sennheisers do not feel as durable or as classy. The feax leather earpads detract from the sense of quality. However, they are thicker than the Beats, and more comfortable around the ears. With the Beats, my average sized ears would press against the speaker, and get sore over time. That has not happened with the Sennheisers. The packaging of the Beats headphones was significantly better than the Sennheisers. The Sennheisers invested in a great sound, and strong battery life, but the headphones, and the packaging they come in are pretty minimalistic. With the Beats, it's an experience to unbox. Everything says quality. The Sennheiser's are like opening an off-brand set of headphones from TJ Maxx. Also, the Sennheiser's come with a soft pouch that offers very little protection to the headphones, whereas the Beat's headphones came with a hard case. The most irritating thing about these Sennheisers is that they glitch regularly. Regardless of what device I'm listening to, the sound cuts out for a nanosecond about every thirty minutes. Not a huge deal, but because it happens regularly, it's annoying. That never happened with the Beats headphones. Once again, my highest priority is sound quality. And the Sennheisers offer better overall sound quality than the Beats. And after sampling multiple other headphones in store, I haven't heard a better sound for $100 than the Sennheiser HD 4.40 (these are back up to $150, but that's more than they are worth, IMO).

      I tried to like them...

      I picked these up to see if I could grab a bluetooth headphone without killing my wallet. I've had Shure SRH440s, used ATH-M50s, and am currently using Sennheiser HD 598Cs, so I've had a taste of decent headphones. I really tried to like these headphones, but compared to my HD598Cs, they just can't compete. This isn't to say that they're bad headphones, but I found myself going back to my HD598Cs headphones constantly. The two advantages the HD 4.40BT had was in the (1) mainstream bass department and (2) wireless function. When I wanted more mainstream bass, they delivered. Considering the HD598Cs isn't wireless, this is obvious that the HD 4.40BT will be better. I did enjoy being able to walk around the house without a cable, it's such a luxury that I will continue to obtain. The sound isn't bad, but it isn't great. I wasn't blown away, but I wasn't expecting to be because I knew I was paying for wireless functionality over sound. Comfort is okay, but the clamp force is a little too tight, and the earcups weren't large enough for me because I got used the spacious earcups from the HD5XX series. Speaking of the earcups, they are made of a cheaper and less dense memory-foam design. If you've ever used Brainwavz memory foam ear cups, they're similar to that, but not as good in my opinion as the Brainwavz. I'd recommend these for people with smaller ears, smaller heads, and for someone who wants decent sounding wireless headphones that don't cost so much. Unfortunately, I shall be returning the HD 4.40BT. It's unfortunate because it was so close to being the right wireless headphone for me.

      I personally have been looking for a good pair of over-the-ear headphones and stumbled upon these. Knowing the name, I knew this company was reputable. Now owning them for a few days, I am willing to share the following: Pros: -Great Sound - It definitely has a really nice pair of speakers in them. I am a nerd when it comes to audio, and when I put them on for the first time I was surprised. -Loudness - If you are like me (which most people are), I really like to jam to music. I am very pleased to to say that they sound amazing even at max levels. -Battery Life - 25 Hours!?! I know that has been around for a while now, but for $150, you cannot argue too much. Now for the one and only bad thing.... The bar that goes across the top of the headphones is really bad. It holds its ground when it comes to stregnth, but when it comes to comfortability, It is terrible. Its almost like they spent all of the budget on the speakers themselves and were just like "this will do" when it came to the bar. After 2 hours or so of wearing them, they really start to dig into your head. This could be a personal problem because I have a big head, but just warning you it could happen to you.

      Great wireless headphones

      Let me start of my saying I am a long-time Senheiser fan. Many years ago I chose Sennheiser because I couldn't afford Stax. So when it came time to buy a set of BT headphones, I was already leaning towards the 4.40BT's. But sound quality is more important to me than brand loyalty, so I compared them to other cans from Sony, JBL, Beats, and Bose. After comparing them all, I found that I liked the 4.40BT's the best for the price. The Sony's and Bose headphones sounded great, but cost twice as much. The JBL's has good sound and great base, but the 4.40BT's sounded better across the entire range. And I just don't like the sound of the Beats. To me they sound flat with extra base. After using them for a week, I am still very happy. I am using them with my LG Stylo phone mostly. The headphones instantly connected to my phone without any issues. I like the fold up sides to make it more compact for carrying, and I find them very comfortable with extended use. My wife also likes the fact that I can listen to them in bed and she cannot hear the music from them. For my first run I got more than 25 hours out of the battery. If I had one suggestion for Sennheiser, it would be to replace the plastic joints with aluminum joints. I am having no problem with mine, nor do I expect any. But this seems like the weak point in the design.

      Not the Worst, Not the Best

      Considering the name I was hoping for something special as I've been looking to get away from Beats as I'm just not happy with the quality for the price we are all paying for them. Thus I decided to give these a try - though I will admit the deciding factor was they were on sale for $100! Even though I had no real intention of buying headphones that day, it's really hard to pass up what could possibly be a really good deal as the demo pair sounded pretty good up against the others (the few demos that actually worked anyway). Pros - Decent, clear sound, fair amount of bass, good battery life, comfortable enough for me to wear for extended amounts of time while I work outdoors. Cons - Volume - won't go above source volume. Headphone parts are pretty much made of plastic. Being such I don't see much longevity. Controls - while pretty much straightforward, aren't the easiest to use or distinguish. Headphone cups - as far as I know they aren't replaceable. In summary: For the cost spent I can't really complain. If I had paid full cost I would have been disappointed. I would deem these a starter set of headphones, for those looking for a decent sound on a budget. They are not by any means a high end pair despite the name...

      For less than 100 bucks, these are a decent pair of headphones. The Bluetooth connectivity is really good, I have had Bluetooth headphones which struggle with walls but I didn't notice any interference while using these. The sound is really good, nothing exceptional about the quality, but that can be expected when using headphones over Bluetooth. The battery life is fantastic! It lasted at least a few weeks before I plugged it in to charge. I have also been using these for phone calls and it works very well, very little muffling of my voice, which I like! The only complaint I do have with this pair is the earcups are too small for my ears. It doesn't hurt me, but it would've been nice to have more spacious room near my ears. The padding of the faux leather is comfortable though.

      Light Weight Undisputed These headphones are light but by no means flimsy. they feel solid and are comfortable to wear. Ear Cup size is decent, though it could be bigger (i know the issue are my ears and not the ear cups). Ear cups isolate noise really well (i use them on a workshop and i cant hear the drills or impact drivers). Sound wise; they are balanced headphones, not too much base good mids and good treble. If you are looking for beats like base look elsewhere.

      Sennheiser HD 4.40BT review
      Sennheiser are a big name in audio, so when it comes out with a pair of big, sturdy-looking over-ear headphones there's a good chance that they're going to be good. Having said that, even Sennheiser isn't immune to the odd shocker now and againFull Review
