Top customer reviews
Here are things I liked about it
1) APT-X no lag when watching movies / playing games.
2) Very good sound. I have the HD 600 that I use at home for music. This sounds just as clear as them. I have a lossless track of Katie Melua & Eva Cassidy singing What a wonderful world. Most headphones tend to muddy the voices to the point where you are guessing who is singing what. Not this one, you can clearly make out the difference between the two through these.
3) These headphones are much brighter than the HD 600's, they have a foot tapping liveliness that is easy to love.
4) Bass extension, the bass guitar riffs sound real on these to my untrained ears. Close enough to the real thing, (I play the bass). Listening to a track like Carousel by Melanie Martinez, where other bass heavy headphones like Beats Studio starts to distort, this plays with authority and clarity. These are no where near as bass heavy as most other gen - next headphones out there, but they are not bass shy either. When they do play bass, they do it well.
5) I flew to Ireland and got stuck in a long lay over situation. The net duration was 28 hours including layover. This paired with a tablet, lasted me the entire time. I had to charge the Tablet 5 times during the trip, this one was still going strong when I finally switched off. The LiPo batteries are awesome.
What I dont like
1) These are on ear for me. I admit I am 6'1 and have elephant ears. Still I have no idea why Sennheiser cant build a HD 600 sized bluetooth headphone ?
I purchased the Brainwavez hybrid headphone pads and they fit right and go over the ears, but that needed some electrical tape to happen and killed the looks of the headphone.
I have this exact same issue with my Urbanite XL as well. Its more like an Urbanite M, not XL.
2) Bluetooth range its good enough for 15-20 feet, LOS, after that it cuts out. It most likely will not be a problem for anyone, but my $ 15 kinivo bluetooth headphones from Amazon has 3x the range, not sure why sennheiser cant do this ? This is not a deal breaker for me, but it bothered me that a $ 15 headphone can beat this in range.
3) The headband doesnt have any real cushioning to it. Its better than urbanite but barely so. After a few hours of extended listening, the top of my head starts to hurt. I fixed this with an add on pad, but that makes this look really bad.
4) The noise cancelling is a an experiment in compromise, I think its set at a mid point between complete isolation and zero noise cancelling. I think that is because complete isolation causes some people to have a perceived headache/ear ache. I have spent hours in the shooting range for the Marines before and I have used the BHP, (Ballistic Hearing Protection). They are really foam based ear plugs with a fancy name. Anyway, zero ambient noise does not bother me.
So for guys like me, I wish there was a more aggressive noise cancellation. Maybe a three level adjustable noise cancellation with the final level set aggressively.
At +/- $150.00, these are great. But if noise cancellation is the only thing you need and sound quality is as important to you as the current drought in Nigeria, I would recommend the Bose headphones. Otherwise, these are quite awesome and slightly better sounding than the Urbanite XL.
Although one of the buttons sticks.. this is probably why it was returned and resold as "Used" if the button worked properly or if I was told before hand that the button sticks I would have rated 5 stars.. oh well. Moving on..
First thoughts were that the packaging was very well done and Amazon also did a good job of choosing a box with filler that didn't allow it to shift all over the place. Inside the packaging it is bare-bones, just the headphones, cable, cheap bag carrying case, and some leaflets. While they are plastic, they did not feel cheap. Obviously that is an opinion and I think that quality plastic can be great in some scenarios, just like metal can be in other scenarios... So your mileage may vary.
I paired these up with a OnePlus 3 (no aptX) and oh boy, what sound. Honestly, listening to music on these was a revelation much like the first time I hooked up a surround sound system to my TV. Coming from cheap headphones that "work" you don't realize how much you are missing from the music you listen too. The sound is super crisp and vibrant. I could hear extra detail from the instruments that I didn't before on much cheaper Bluetooth headphones. I feel like the bass was there, but not overbearing. I am not a bass head, so people wanting super saturated base probably should look elsewhere, in my opinion.
Now for the bad. I have a big head. I am the sort of person that dies a little inside when you look at a hat and it says "one size fits all". Liars. haha. I ought to have listened to some of the other reviews that I had read stating these were not rainbows and butterflies on large heads. The biggest issue are the size of the ear cups. For anyone with adult sized ears these will likely be closer to ON ear as opposed to OVER ear. The material is nice and soft (a faux leather of some sort), but with it all on my ears, it got roasty pretty quick. On that same vein, I feel like because of the size of my head, they didn't quite fit comfortably and would get a little uncomfortable on the top of my head and to a lesser degree my ears after wearing them for a while.
I will be honest, I did not test the Active Noise Cancellation (ANC) much. It seemed like they did a decent job killing general ambient noise, but I don't really have anything to compare them against as a reference for "WOW these are amazing" levels of ANC. Honestly, for half the cost of the "Golden Standard" of ANC (Bose QC35) you can't expect it to be earthshattering. I will say that the "white-noise" that some older ANC headsets has is virtually non-existent, which is nice.
I don't want to discourage people with smaller heads from these. The sound you get is awesome and you get the bonus of great battery life and ANC in an exceptionally reasonable price. I would give it 3.5 stars if I could, but I want to be sure that people with bigger heads think twice before they buy these. Maybe I just have a sensitive large head and other people wouldn't find my qualms an issue, but I want to put out the word regardless. I ended up returning them and am back to researching a decent set of headphones that won't cost me a kidney, but will cover my big head and ears.
+ Quality plastic construction (yes, plastic and quality can be in the same sentence)
+ Great sound, super crisp and vibrant, bass not overbearing
+ No sound bleed (at volume levels that won't make you deaf)
+ Great battery life
- Marketed as OVER ear, really actually ON ear
- Uncomfortable on larger sized heads
- Ear cups, though comfortable, warm up quickly as they are on your ear (not over)
* Active Noise Cancellation is nice, but not phenomenal
* Price to sound and build quality ratio is great
* If your head isn't huge... these are definitely worth looking into
* If your head is huge... you probably want to look elsewhere
