Excerpt: I primarily use this headset while commuting by bus to work. It does an OK job of passively sealing out ambient noise, but if someone with loud and leaky earbuds sits next to me, I can still hear their music. In a noisy bus environment the sound quality is somewhat diminished, and the volume, while using bluetooth, is quite limited.
Pros: Comfortable, Easy Controls, Good Material Quality, Replaceable Battery Pack
Excerpt: They work perfectly with my i-phone, my computer or any device I can pair them too. I use them for talking on the phone in the car, watching movies on i-tunes and video editing. The sound quality is amazing. You can hear every detail. The microphone works well also. All of my callers, say that the audio quality is very clear and I even dictate notes on my computer using them. This is just what i was looking for. They are very comfortable and light weight.
Excerpt: Very comfortable. Very good sound. A little pricey vs other BT Headphones I have. The longevity will tell - but so far worth the extra $$$. BIG PLUS - Easily replaceable battery pack for those long plane rides.
Summary: Nice headphones, nice price. A bit fiddly charging the battery. Fidelity wise very good and an improvement on my last sennheiser phones. Major minus though is that it is not supplied with a spare battery and they are only available from limited sources at an extortionate price. Pity this was not made clearer on the advert. Sennheisser seem to be the only suppliers and charge through the nose for them. How can a tiny battery ever be worth £40...I could buy a tv for that.
