Good sound, but design flaw that will eventually lead to failure.

Summary: I have owned these headphones for 18 months. Sound >> these headphones take about 2 weeks of regular use to wear in. At first the bass particularly is very lacking and the high end a little harsh, but eventually they wear in to a nice balanced sound, if a little quiet overall and when listening in a noisy place e.g on the bus, you lose the bass entirely.
Excellent product delivering very acceptable depth and detail for this ...

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.
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.
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.
