Audio Excellence at a Great Price
Color: 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! ... show more

Just like his old pair!
Color: Black
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! ... show more

Best bang for the buck wireless headphones
Color: Black
Comfort and build: comfort is lousy because the cups are too small. I can't wear them for too long because my ears will get sore. If they were just slightly larger this would not be an issue. My ears are not that large, so unless you have small ears this might be an issue. The button layout is terrible, too many similar buttons and the power button is hard to reach. Build wise, it is all plastic but feels well designed and durable. Noise cancelling: THIS DOESN'T HAVE IT! There are so many trash reviews right now. Look the 450 model has ANC, the 350 model does not. Don't be fooled by those bad reviews. I intentionally bought this model over the 450 because from experience I know that Sennheiser does not do good ANC. Sony and Bose are where you look. Sound quality: above average for wireless headphones. The bass is muddy and never impactful. The mids are overly recessed and the treble is too much. It gives the headphones a dull, thin sound. A bit of an exaggeration but it is like listening to AM radio. It is NOT at all the Sennheiser house sound (rich warm, dark and highly detailed). It is also not terribly detailed. But it is better than most wireless headphones that have that consumer-grade sound of incredibly flabby, muddy mid and upper bass boost. The best I've heard are from Beyerdynamics, AKG and Audio-Technica but their offerings are much more expensive or lacking in features or are poorly made. Comparison to the 4.40: this headphone is the spiritual successor to the 4.40. The 4.40 was a terrible headphone. It had an audible noise floor (I listen to classical music at low to mid-volume so the hiss was always present). It had poor support for codecs and did not have much in the way of volume or dynamics. Finally, the 4.40 took micro-usb for charging. This headphone is much better. Sennheiser clearly redesigned their wireless headphone. There is no noise floor on the 350. It supports nearly every codec you can think of. It uses bluetooth 5.0 and has usb-c with fast charging. Verdict: at $100 you can't do any better. It has the best sound quality, build and features at that price point and comes from a name brand. Notice I didn't praise it to the moon. Temper your expectations. It is impossible to find great SQ or great NC on wireless headphones without setting a pretty steep budget. And there are no wireless headphones that hit both out of the park. It is unfortunate that Sony and Bose have such great ANC but such lousy SQ, and all audiophile brands put so much effort into SQ but almost no effort into NC. ... show more

Great quality and durability
Color: Black
Amazing sound quality for the price and overall good connection distance. Having smaller ears the pads are actually perfect. Very durable and survived many falls and being wedged between stuff with no problems.
