SennheiserHD 350BT Black Bluetooth 5.0 Wireless Headphone - 30-Hour Battery Life, USB-C Fast Charging, Virtual Assistant Button, Foldable - Black

Let me start by saying I am an amateur audio enthusiast that loves a balanced and detailed sound signature. I don't care about making phone calls or active noise cancellation (ANC). For the most part, I wear headphones in quiet places to listen to music and ANC usually messes up the sound signature anyway. Just give me good audio with passive noise isolation and I am satisfied. Second, I don't care for the bloated bass you find in most consumer headphones. Just let me hear what was recorded with clarity, detail, natural tonality, and a great sound stage. I've spent a modest amount on DACs, amps, earphones, and headphones to deliver the kind of sound that makes you remember why you love music so much. But there are times when I just want to kick back and relax and not be tied down by wires. My solution to date has been EarStudio's ES100 and a good pair of IEMs. The AAC codec from an iPhone using high-quality music source (FLAC, Amazon Ultra HD) with high-end in-ear monitors sound reasonably close to my wired Drop HD6XX or Hifiman HE400i cans on my Schiit stack. I had tried a few over-ear Bluetooth headphones but nothing has ever sounded even close to what I consider high quality audio. Either too much bass or an ANC system that interfered with the audio signature (on or off). Nothing met my amateur audiophile aspirations. That is until I got Sennheiser HD 350BT. After reading a few of the reviews, I almost didn't order them. But for under $100 I decided to take a chance. From the first listen I was blown away by the balanced sound signature. Not that far off from the Sennheiser house sound signature. After 20+ hours of breaking them in, the bass has opened up just a little and the mids are still wonderfully natural and perfectly placed evenly in the mix. And while these are not as good as a wired over-ear headphone on a high-quality dac/amp, for a wireless audio headphone solution these come close enough to free me from the wires and not feel like I am missing much. The bass is solid from sub-bass to mid-bass without muddying up the lower mids. These are not consumer bass-head cans with bloated bass. You can feel the thump of bass drums and toms on ears. The bass is present way down into the frequency range, but there isn't an overpowering slam nor is it the star of the show. But it is clean and surprisingly detailed. And the sound app EQ settings, which is too simplistic, still let's you bump the bass some if you need a little more. Listening to Marcus Miller on Laid Black is great for illustrating how well these handle the lower frequencies. Miller's bass solos are a pure pleasure listen to. Mids are where many headphones fall short - either missing the natural sound of voices and instruments or placing them behind/under the bass and highs. Yet this is where much of the audio is in most genres of music. Voices, guitars, strings, woodwinds, brass, and snares/toms bring the bulk of audio that is to be heard. The HD 350BT shines here. Sennheiser really shows they know how to shape a balanced sound signature around high-quality mids. Listening to Boney James on Future Soul I heard a natural and realistic alto sax sound that is so, so good. The highs are also very good and actually somewhat relaxed for Sennheiser. I prefer just a little more air and sparkle, but even without EQ these are delightful. However, using the very-basic EQ settings in the Sennheiser Sound Control app I was able to bump the highs to add exactly what I was looking for. Cymbals and triangles ring clear and the detail and imaging provided is very good for Bluetooth wireless audio. No distortion, sibilance, or feel of grainy treble. You can hear small details of instrument decay, reverb, and echoes in the room. Listening to the Marcin Wasilewski Trio with Joakim Miller on Spark of Life, I was able to hear the detailed clicks of drumsticks and subtle crash of cymbals of Michal Miskiewicz's excellent musicality on the drums in each song. But what I love best about the HD 350BT is the excellent dynamics and sound stage. I'm not sure how Sennheiser worked their magic building a digital audio decoder and amp into a headphone that delivers such an excellent sound stage. But I am very happy they did. They sound equally good at low volume or high. Overall dynamics from soft to loud is incredible for a wireless audio product. The stage is wider than average with a good bit of depth and height. They detail of the highs provided just enough air give that sense of spaciousness and realism I really enjoy. It really put these over the top for me. Note that these are not the loudest headphones and to get these cranking they need to be in excess of 75% volume, which does not leave much room at the top end. But given the excellent passive noise isolation, they are more than loud enough for most, even in a moderately loud environment. The Sound Control App is marginally useful. The EQ works, but is essentially a three-band equalizer that can be toggled between a hard to use visual representation or a linear hi/mid/low band setting that is easier to use. I do wish that Sennheiser could have provided a 5 or 7 band EQ. But as I said it works - just could be better. I also found the HD 350BT headphones to be very comfortable and can wear them for hours at a time with no discomfort. That said, the ear pads are soft but somewhat small and could be problematic for someone with larger ears. The build quality is solid despite the plastic material used for the majority of the body. They also look great in black to me. But don't expect frills, a case, or even a bag. The focus at this price is on a great audio, not accessories. If you are more of an audio purist, love the natural sound signature/tonality of Sennheiser products and don't care about ANC, then these are a huge steal at under $100. Forget the HD 450BT and it's ANC, get these instead. And no need to spend $300 or more on Sony and Bose. Spend your money on great audio. These simply sound great!

Bought these for my husband due to his old pair of these breaking after 5-6 years of every day use! They fit very comfortably around the ears fully allowing them to sit inside of the muffs without them pressing down onto them, my husband wears glasses and keeps the headphones on basically all day and has no complaints. They are a slightly different colour than the old model, this version being a sleek all black look. They are very clear sounding but not really heavy on bass, just nice clear surroind sound that is very well dampened from the outside allowing for an immersive experience playing video games, watching tv or listening to music! They seem to charge pretty quickly but I don't ever put them on the charger myself I think it's about 3 hours of charge time and then they last about 16. I feel like it overall it was a really good price and the headphones work extremely well for what he uses them for which is gaming music and watching TikTok! I enjoy putting them on sometimes just for the active noise dampening!

I was not over-impressed with these at first, they were OK. The ear cups are small but I wanted that. They are not super comfortable, especially the headband. But with time I've become very satisfied with the sound for the money. Not overly bassy (if that is what you want look elsewhere). The app is... not impressive. Very basic but I only needed it for updating the firmware. I only use them for TV/music so I can't speak to any calling features. They don't have ANC and I guess passive noise blocking is OK. (I use my NC buds when I need noise canceling) They are not particularly bright, you are not going to notice a bunch of new details in your favorite songs but the sound is balanced across the spectrum of instruments. No big peaks or dips. I like them enough that I'm getting the Momentum 4 and will keep these for outside. If you have large ears, these will be on ears... you might want to consider the HD450 BT or the new Accentum if your budget stretches that far.

This is a great sounding headphone let down slightly by its audiophile tendencies. The main culprit being lack of bass. You see, human ears hear midrange just fine at all volumes, but as you lower volumes, we hear high frequencies lesser than mids and bass frequencies even lesser than high frequencies. Therefore, the correct EQ needs to have a good bass boost and a slight treble boost. This will give a balanced sound to our ears. Reason I say this headphone is let down slightly by its audiophile tendencies is because it produces sound using a flat EQ. This just makes the sound appear as lacking bass and treble. Using the app you can adjust the EQ and get the correct perceptual balance. I would also highly recommend going through the sound check process in the app. As a starting point, I recommend setting your bass at +5 and treble at +2.5, leaving mid at 0. Now that we have setup out of the way, the sound quality is amazing. You’d be hard pressed to find a significantly better sound at this price point. The sound stage is very wide and instrument placement is very clear. The dynamics are also great if you’re watching movies. I would highly recommend this product - just be sure to use the app and dial in the sound!

If I had to sum up these headphones as simply as possible, I would say that you get exactly what you pay for - no more, no less. They're good headphones from a good brand. The Sennheiser name was what initially drew me to this model, but the user reviews were what clinched the deal for me. However, I feel like the majority of the user reviews were somewhat exaggerated. My impression of them when I first start listening to them the first time and pretty much every time since is that they're a little flat and muffled. I wouldn't consider myself to be an audiophile, but I would describe the initial sound to be a little plastic-y, if that makes sense? There's a Sennheiser app with an equalizer to play with, but any notable adjustment causes distortion and fatiguing. However, after several minutes of listening something happens... You start to realize that the bass is deeper than it seems and there's a lot more sound staging than what you initially thought - most of the time you can hear every instrument isolated. Every listening session is pretty pleasant, but the headphones themselves are not super fun or dynamic. Certain production choices/styles can make these headphones sound cheap and grating, while other times you can hear the full texture and richness of a song. I bought these to hopefully be an upgrade over an older pair of Sennheiser Momentum Bluetooth headphones that charge via micro USB (instead of USB-C), but they are not an improvement as far as sound goes, only convenience. The passive noise cancelling is excellent, but they're a tad bit hot and uncomfortable on your head. The build quality is somewhat questionable and I feel like they might break if you used them too carelessly, but that's still to be determined. They would be an excellent value at $50-70, but as it stands, you're not getting anything more than your money's worth.

These are very comfortable, but I have a small head and ears. I wore them for about two hours in the heat and had no issues. After downloading the Sennheiser app, you have options of playing a song and customizing the sound to your liking, I loved this compared to my Beats. They are supposed to work with Siri, but it is really lacking and the sound when you contact Siri is very low, no matter what volume you have them on. Compared to my Beats, these are better in sound, comfort and quality. They feel sturdy and not light. I wore them outside in a busy setting and they really reduced outside noise significantly. I used them with an iPhone 13 Pro max. I copped them at a bargain price during Prime Day.

I paid $80 for these, marked down from $90 at the time. I would leave two stars, but it looks like the asking price and markdown vary wildly from time to time and I'll dock another star for that nonsense. In no world are the quality of these worth the current retail $120. Sound quality is what I'd expect from $40-$50 headphones, and there is just way too many controls on the earpiece. I find myself bumping the switch for skipping tracks frequently and when listening to youtube, that often loads the previous/next tab and is a whole minute or two affair to get it back to where I was. I wish it was just a button like every other headphone model does. Additionally, it won't charge while turned on, and won't turn itself off when plugged in. Even the b.s. $40 skullcandys I was using before these were able to do that. They also run small, and while I have a smaller head for my size, I'm sure these are uncomfortable for anyone with a larger than 7 1/2 hat size. The good though, is that the battery life on these is excellent. I was wearing these while building a house, and I'm pretty sure I was getting well past the advertised 30 hours, and into the 50 hour range. They charge very quickly too, so if that all matters to you, here's an option. Mid audio quality, and poor device controls make this an insane purchase for the 'retail' of $120. You're crazy if you pay that for these. I'd recommend just getting either a different product at that price point, or some run of the mill $40s.

I had a sony wireless headset before these that didn't last a year and which I paid twice as much for. These Sennheiser headphones sound great, something I've gotten used to having used their wired headphones at work for years. They fit well and are comfortable. The controls work great and these are still alive and kicking a year later. My only complaint is the power button on the headset sit's even with the surrounding surface and can sometimes make it difficult to get them to power on as its hard to find the right spot without holding them and looking at it. But otherwise a great product!

انصح بهذا المنتج صوت واضح مريحة

No me decepcionaron estos audífonos, pero tampoco quedé encantado. La calidad de sonido es bastante buena y muy clara, pero nada excepcional. Definitivamente no es para gente que le gustan los bajos potentes. La cancelación de ruido es buena. La duración de la batería es excelente. Puede llegar a durar más de una semana, depende que tanto los uses. Lo que no me gustó tanto es que no son muy cómodos después de una o dos horas, pero se arregla con un descanso de diez minutos.

I use these almost every day, when my partner watches tv in bed, i just put these on and watch my own things
