The PXC 550s have a fantastic battery life, divine sound quality, and are decently comfortable

Battery life was phenomenal

The battery life on these is insane, I have the habit of charging things often no matter the % but these literally never need charging

Battery life is amazing, comfort is amazing, sound quality - AMAZING

I do wish they were a little smaller package (when traveling, they take up more space in my carry-on than I'd like), but again- sound quality is good and battery life is quite good.

Battery life seems good too

Excellent sound quality, great battery life, connects quickly and stably, great pass-through mode, great noise-cancellation

The battery life is good too, only charged once for return flights

Battery life is good; I've not measured it, but I'm so used to them just working that I'm always surprised when they need

Battery life is excellent.

Also - The battery life is unbelievable

Battery life is amazing I've charged them twice in the 3 months Ive had them

The battery life is stupendous and they charge extraordinarily

This battery life is absolutely ludicrous

The battery life is good, but once the headphones reach 20% battery (which is still plenty to go for most of a day), they start playing a low-battery announcement every couple minutes over the audio

The battery life is excellent, somewhere around 20 + hours

Battery life is awesome and I am really impressed

these are great headphones comfortable and long battery life.

Superb sound, ridiculous battery life, and great Bluetooth functionality

Battery life, comfort, sound quality etc. are great.

Read Several reviews before I purchased the PCX550's , I really love the fact that you can plug the headphones up to the computer and still listen to music (via Usb drivers) whilst it charges via usb, the battery life is amazing and the touch features fuction as advertised

The best headphones I've owned, including Beats,Bose Easy to use, great sound, longer battery life, and the noise cancelling works better than the Bose, IMO.

Battery life is excellent, and I never have been able to count the actual hours of use to see if the rated battery life of over 20 hours is accurate

The battery life on theses things is epically good, first charge lasted me a week

Lastly the battery life on these is amazing

Wireless noise canceling and a 50 hr battery life

I've always heard great things about Sennheiser and the sound quality of these headphones is as good as or better than every other model I tested, including wired ones in this price range

Be sure to follow instructions for the Pause Play option or it won't work as

Brother in law recommended these to me as he is purchasing a pair of his own

Bass is strong – but not artificially emphasized and muddy as it is on so many other headphones

Then I took a call and started typing on my computer: I could hear every click as clear as if I didn't have headphones on.

The Bluetooth paring with my Android phone was flawless, as well as with an MP3 player.

Definitely a solid A from a first-time headphone buyer.

Sony has a pocket inside for the airplane adapter, then a mesh pocket on the outside for a cord (which I don't like as it tends to snag when you're stuffing the thing inside a bag - would have rather just had the pocket on the inside)

I have also noticed that the noise cancelling does not seem to be as effective as with the 550s, but I do not notice as much wind buffeting.

It's easily paired with multiple devices and intelligently fails over between them as they become available

They aren't as sensitive as an

: I primarily listen to hip-hop/R&B/ as well as classical

/PC.PRO: The build quality is, while not amazing, far superior to the cheap plastic-y look and feel of the Bose QCCON

not as good - I urge Sennheiser to look to tomorrow and do something cool

and I didn’t really like them as much as I though I
