  • Summary: Excellent product delivering very acceptable depth and detail for this type of headphone (ie Bluetooth) and not much to complain about. Tiny niggle is the overall full volume could be a little higher. :) as good as most middle range cable headphones upto £80.

OK but way too quiet.

Soapy Tyler "spacemonkey", Amazon

  • Summary: I bought these because they use the AptX codec and because Sennheiser have a good reputation. The AptX codec does offer significantly better sound over the standard A2DP codec and if you are after a pair of bluetooth cans then definitely make sure they are AptX enabled. I got these for use when I'm out and about, traveling etc. as they fold down to a very easily portable size.

Good but not Great!!!

Mak, Amazon

  • Summary: Pros: 1. Good sound 2. Works quite good with Bluetooth 3. Battery for bluetooth can be removed from headphone and put separately for charging which is cool. Cons: 1. Iphone volume control or song change controls doesn't work when u connect through wire with ur iphone which works perfectly when bluetooth is on even when u r connected through wire. 2. So called head supports on top starts hurting after using it for couple of hrs.

Generally brilliant.

30 May 2014
  • Summary: I bought these because I always liked the idea of wireless headphones. I am not disappointed. They paired with my computer perfectly (iMac Late 2013), and charged fully after a respectable 3 hours. I have yet to run out of battery and I have been listening for a good 8 hours. Sound isolation is better than I expected, very little sound escapes even on max volume (which is only really noticeable when in a silent room) They are easily foldable, very lightweight and come...

Not compatible with PC?

Wolfy85, Amazon
29 March 2014
  • Summary: They worked straight away with my Galaxy smartphone, good sound too, but don't seem to be able to play the music from my bluetooth enabled HP Envy Dv6 PC...although the pairing was successful with it, and the headphones show up as connected on my PC, but sound continues to play through PC speakers, even with headphones switched on, I keep getting the blue flashing LED light, indicating the device is out of range, even though it's not the case..any ideas? Many thanks.

Much better than beats

Lauren Picton, Amazon
23 January 2014
  • Summary: My husband and son both have beats by dre headphones which are falling apart so I decided to look for a different make and was recommended sennheiser. Although the beats have a slightly superior sound quality, the build quality on these are much better. I love that they fold up and the Bluetooth feature. They have a long battery life and are easy to operate. I would definitely recommend these over the beats.
