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!
These beat the crap out of all my wireless IEMs in terms of sound quality, which makes them the headphones I use most often because I don't usually want to be tethered to my amp. They work great for phone calls, and the sound is pretty good in all frequencies. I wouldn't say any part of the sound spectrum is particularly outstanding or lacking... just adequate all around. I am happy to have these headphones.
Top reviews from other countries
- Good build
- Aptx LL
- Fast Pairing/Power On (most BT devices I own you must press Power 4 seconds. This one is 2 seconds and feels lightning fast lol)
- Good battery life
- They fold for storage
- Tinny sound. Capable drivers but must be improved with EQ. You can set permanent EQ through an official mobile app, although it's very barebones EQ.
- Comfort is very meh. The earpads are over-ear but the holes are too small. I believe I'm a pretty good benchmark for "medium-sized people" and my ears can't comfortably sit in there. Holes are too big to wear them "on-ear" as well, so I ordered bigger, third party replacement earpads. If you have medium-sized ears (not unusually small or big) you will probably need to as well. Another bummer is the headband. What feels like should be a simple, comfy, spongy rubber is actually too thin and stiff. I think it's mostly because I have short hair, but after a while the headband will have nested its way onto my scalp, like between patches of hair, and the hair it pushes back will hurt after a while. I don't have this issue with other headphones that have a slightly larger, more flat headband. YMMV, but for sure this isn't a winner design.
- Active microphone monitoring when in a call that you can't disable. You hear yourself and your surroundings when in a call and this ruins both the sound quality and what little isolation the puffy pads would provide (they do block off sounds fine to me, but it's nothing like Active Noise Cancelling obviously). This was a solid 3 stars upon this point. I bought these phones primarily to play games with Aptx Low Latency on my couch setup, but they have a decent mic that I wouldn't mind using for calls on my phone (Skype, Telephone, etc.). Apparently this is a feature as there is no way to disable it (according to many people with the issue through Google), and I guess it makes sense for ANC headphones like the 450BT variant (I think the "feature" is present in my 350BT variant by error), but even then that should be up to choice, togglable. Also this is a problem for me as I wouldn't mind disabling the mic through the OS and using the phone's mic, but on Android it's just not possible to choose separate Input/Output audio devices like you can on PC (maybe you can on iOS, although my hopes are low). So either I use the headphones in my calls and the experience is terrible, or I turn off bluetooth entirely. There is no in-between. Good Bluetooth headphones with no microphone are also incredibly rare (if they exist at all, wasn't lucky to find one), so that's also not an option (to me, yet). This "feature" is also surprisingly annoying because my favorite pair of BT headphones have a very bad mic, to the point that I can't use it because of how bad I sound others (unintelligible, not just bad sound), so while I'll be keeping these Senns for couch gaming, I'll have to find another pair for hands-free calling.
- Price. Expensive for what you get. These feel like they should cost no more than 60$-75$ because when I compare them to my cheap, disposable 35$ bluetooth cans, they're outmatched in all the aspects that matter (to me): Sound quality, comfort, battery life (the Senns' battery life isn't bad, just not as good). These Sennheiser cost almost 4 times the other pair and to me that's a con. Is it Aptx that raises the price that much? I wouldn't know. Definitely feels overpriced for what I got/can get elsewhere.
- If you want Aptx Low Latency, shop elsewhere, there are bound to be headphones with better sound, comfort and maybe other features than these at a similar or lower price.
- If you want to use it as an Android hands-free calling device, shop elsewhere in the 40$-130$ range. If you don't like hearing your own voice through the same headphones (microphone monitoring), there are plenty better options.
- If you just want bluetooth headphones with decent sound and comfort, there are much, much better options for as low as 35$. Look elsewhere.
Sadly can't recommend this pair of otherwise premium-looking headphones. Constant microphone monitoring was the deal breaker to me.
(I would love them to update firmware so that is possible, and there's hope, as this model line is quite recent. Will update review accordingly).
Solo tengo dos puntos que me parece importante mencionar, a la hora de la compra no me percaté que no tiene entrada jack para audífonos, son completamente inalambricos, para algunas personas pueden que esto sea una ventaja pero de haber sabido esto antes me hubiera comprado la versión que si tiene la entra jack.
Tuve problemas para vincularlos a un samsung galaxy 8 y 10, pero me parece que es problema de la versión de la aplicación de play store ya que no tuve problemas para vincularlos con un iphone y con una computadora Dell.
They don't connect to bluetooth anymore, I've tried with 1 windows laptop, my cellphone and my chromebook.
Battery at 65%...
Total waste of time and precious my money, Sennheiser became crap, don't buy headphone.
