This headset can be connected to an audio source via Bluetooth, USB or 3.5mm jack. USB cables and 3.5mm audio are included in the box so you can connect virtually any audio source nimporte. In Bluetooth mode, you can pause the music and answer calls with the built-in microphone by pressing a button on the headset itself. In addition, there are volume keys and forward / back to the slopes. (These only work for when quen Bluetooth headset is attached with the audio cable, you can control your music directly to your notebook or MP3 player). Autonomy long term at least 8 hours on my own, which is quite enough between loads. Shipments are made with the USB cable.
The headphones are extremely comfortable. Leger and very well damped, I have worn for several hours without being aware that it was on my head. But the real test of a helmet is the sound quality. For a first try, I have listened to an album by Joan Armatrading with a fairly rich production (since you ask me, the album was Whats Inside) and the sound was fantastic. There was a distinct and clear sound with good high register and one of the best bass response that i heard with headphones. The headset also works with any other bie music i tried, choral 16th century Completion Led Zeppelin. For some, the low level can be a bit much for classical music but it's a matter of taste and what nimporte Rock is awesome.
I Navais not intend to ramble but jécoute much music with headphones and I think it is really excellent. It is much more advanced than my Sennheiser HD448s there is almost at my favorite Bose QC2s. Maybe I'll say that it is best for rock and blues that QC2s. It is a helmet with very good value for money especially for the quality of his that it offers and I highly recommend it.
