Customer Ratings & Reviews

Sennheiser is definitely a brand that is synonymous with quality audio products. The Accentum Open are not my first of their products, but I have to say, I don’t feel they represent the quality that they are known for at least not when listening to music. I struggled at first to like these earbuds as I predominantly use earbuds to listen to music, YouTube, and podcasts. And it is the later two where these buds are the best. The bass is really low, so makes hearing the spoken word really easy. In music and some movies, you won’t get that immersive feeling, but you definitely won’t have to stop and replay to catch what was said or turn on Closed Captioning. Device setup was very easy, NO APP necessary to setup, but that also means no way to change any of the tap commands. Connection was easy, but according to the quick guide (see photo) you have to open the case, plug in to charge for 15 seconds, then go to Bluetooth settings on your smart device, press each bud for 3 seconds to connect. The lid is extremely easy to close, so I must have closed nearly 3 times in the 15 seconds when I had them open and trying to plug-in to my laptop USB port. Honestly, not sure how necessary these steps are as I didn’t even take the buds out of the case and my phone recognized the buds and paired. I did try the companion app too, but it does not recognize the buds and there is even a spot in the Help section for these buds that states the app is not needed. The buds themselves are very light which is nice, but the “ear” part of the bud is the same molded plastic as the posts which translates to being slippery in the ear. If you want a set of buds to just have sitting next to the couch or bed and you won’t be moving around much, these would be fine for that. However, if you plan to be walking or moving around then I am not too confident that these would stay in. Workouts and bending over are definitely out. Of course, everyone’s ears are shaped differently, so your usage may be different than mine. Typically I need a silicone cover to keep a bud in my ear. The touch controls are very responsive and that I will say is a huge plus. When taking out the buds though, most these days have a near-field auto stop as it recognizes the buds are no longer close together. These apparently do not as when I was trying to take the right bud out, I was holding on the touch point and it was changing the volume and starting/stopping the playback. I was expecting a different kind of Sennheiser quality that delivers more immersive sound, but I got something different that makes hearing the spoken word easier. Speaking to the lack of of a companion app again and the buds being named Accentum OPEN, Sennheiser has removed the need for pass-through hearing as the buds are designed natively to allow that. With the low amount of bass this is also achieved. I can definitely recommend these buds for the niche person who is wanting something more than just music listening and prefers the spoken word. The two biggest knocks against the product are the ear fitment and music quality.

I use a lot of different ear buds from a wide range of brands.  In my experience, the best sounding ones are the ones that fit perfectly inside your ear.  Anything else causes them to be either uncomfortable or have really bad sound.   These Sennheiser Accentum Open ear buds are not meant to be sitting deep in your ears and so they don't include any rubberized tips to help with the fit and the sound quality.  In my opinion this just means that if you're looking for great sound quality with deep bass response, you surly won't get it with these.  That's what I thought before I even tried them out, and that is exactly what I thought after using them.   I do like some things about them, but the sound is definitely not one of them.  The overall sound is about as thin as I could imagine.  Couple that with the complete lack of any bass response and what you have is a set of toy ear buds.  I get the fact that they sit in the outer part of your ear.  Not everyone wants to cram ear buds in their ears and most are by nature, uncomfortable.  I get the fact that they're comfortable.  Probably the main complaint of most ear bud users is that they are NOT comfortable.  And lets face it, everybody's ears are different, and to make them comfy for everyone is almost impossible.  I get the fact that you can still hear what's going on around you.  Some people like to use them out in public, whether their on a train, walking down the sidewalk or shopping for groceries.  But these let in so much outer sound that it's impossible to not be distracted by it altogether.    The case is another disappointment for me.  It's really annoying to have to deal with a case that doesn't stand up on it's own.  And with a rounded bottom like this one has, it requires two handed operation, no buts about it.  The buds sit in the case so deep that they're difficult to get a grip on to pull them out (other ear bud brands suffer from this as well).  I can't really find anything good to say about the case other than it holds and charges the buds.  Which, by the way it won't do wirelessly, so you'll need to make sure you always have a charging cable and charger with you.  The cable, they give you, the charger, no.   I will say that when you finally do get them out of the case and wear them, they are comfortable, which is something I've never been able to say about a pair of Sennheiser ear buds before.  I like the controls on each side, they're intuitive and they respond well.  The handle portion of each one is easy to grab and remove (or put in), and they look pretty cool.  You can turn the volume up or down, play a previous or next track, pause and play, and answer a phone call.   But for me, I value sound quality more.  So everything I've stated already is true, but is it a bad thing?  That depends on how you use your ear buds.  If you like outside sounds getting in because you're in a public setting, this may actually be a good thing to you.  I can only offer my point of view from how I use ear buds.  I use mine, for the most part, when I work out, running, lifting or just walking.  I occasionally use them to help drown out external sounds and escape to my favorite music.  So from my point of view, I don't like them, they don't work for me because of the thin sound.  Turning them up all the way not only didn't help, but I just could not get them to go loud enough.  They remind me of some smart sunglasses I have with built in speakers.  They play music too, but they don't sound good.

TLDR: Crystal clear high frequency details but lacks any real form of bass response. No ANC limits overall appeal. PROS Lightweight and no annoying silicone seals for the ear canals IPX4 Rated Up to 28hrs of playback Bluetooth 5.3 Crystal clear high frequency reproduction CONS No ANC Extremely limited bass response No voice guidance USE The Accentum Opens couldn’t get much easier to use. Aside from pairing with your phone or tablet, there is nothing else to do. No apps, no customizations, nothing. Pair and go. Sennheiser claims the Accentums remember up to 8 devices they have been paired to. I have paired them with 4 different devices (a mix of iOS and Android) and so far, they have switched seamlessly between my mobile products. One thing that is frustrating is that when you put the Accentums in, they try and pair to the last device used, even if it is not the one you want to pair them with. I often am forced to unpair from my phone to get them to pair up with my tablet. With there being no app, there is no way to customize the sound. No equalizers, no tuning. Only what is included with your choice of playback device. Partly because of this, I find the Accentums have very limited bass response. They are unable to effectively reproduce those low frequencies in any convincing manner. However, I cannot complain about the clarity of the mids and highs. Middle and upper frequencies are exceptionally clear and detailed, better than many of the competitors’ products. I found myself noticing different instruments in songs that I didn’t realize were a part of the band. Slick. NEGATIVES Like I stated above, the Accentums have very limited bass response. Honestly, the Accentums are the weakest at bass reproduction of any of my listening devices. More anemic than any other ear bud I’ve owned to date. Lastly, the Accentums don’t have any form of Active Noise Cancellation. This makes for an often-noisy listening environment. Wind noise is very frustrating with the Accentums. FINAL THOUGHTS The Sennheiser Accentum Opens have great mid and high frequency audio reproduction. Clear and detailed mid and high frequencies are where the Accentums shine. But, as clear and detailed as those frequencies are, the low-end response is poor, making for a lackluster listening experience. I compared the Accentums back-to-back with my kid’s earbuds produced by the famous fruit. If I had an iOS device, I would not look twice at the Accentums. The fruit-based product has a lot more features and though they are a few bucks more, they offer superior performance. While the Accentums are extremely comfortable and have decent battery life, the lack of ANC and low frequency response would steer me away. NOT RECOMMENDED

hard to sync to my iphone. had to return. they look great though. I wish I could of synced

[PROS] Great Battery: Battery life is the best feature of this phone. It lasts for a majority of the work day before needing a charge. However, it charges very quickly allowing me to get longer use. Decent Build Quality: I'm very satisfied with the construction of the earbuds. Although they are plastic in material, all plastic construction isn't the same. Earbuds you find in the checkout line don't compare to the ACCENTUM Open. I heard my environment well enough when my volume wasn't moderately high which was a positive. Above Average Sound Profile: These earbuds are tuned prior to using them. Personally, I think the default sound settings is decent enough, but it doesn't fit every category. [CONS] Severe Limitations/No App: The biggest flaw in the ACCENTUM Open is there's no app to do tweaks or changes. This creates a domino effect of missed functionality. There's not a way to disable or repurpose earbud tap functionality. This means that all adjustments have to be made physically. EQ setting profiles are also unable to be created. Although firmware updates may be unnecessary, they obviously can't be done in a straightforward manner if needed. [MIXED BAG] So-So Microphone: This microphone isn't strong, but it works well enough. I can have conversations with friends and family just fine, but its not outperforming similar products in its class. Okay Fit/Comfort: These earbuds are only mildly comfortable. In my opinion, they're not gentle enough on the inner ear to wear for more than 2 hours at a time. Furthermore, I found myself needing to readjust the the earbuds because they felt like they were slipping during certain activities. This happened more than I would have liked which doesn't instill much confidence in me using this product consistently on the go. [CONCLUSION] The ACCENTUM Open leaves much to be desired. Although they sound fine, they are not special. The lack of control takes away from the user experience, and I don't find them comfortable enough to use them as my daily driver. The "openness" of the earbuds was alright and Bluetooth switching performed as expected, but nothing was ever game changing. I feel like these earbuds are average with small pockets of greatness inside that can't be unleashed. Therefore, I can't recommend them.
