Delivery time as usual super fast. After unpacking only again fully charged and then coupled with Galaxy Note 2. This process was done after a few seconds, without that I had read in the manual. The processing and optics of the Sony headsets are typically very valuable! The sound transmission from the mobile phone is trouble-free and of very good quality. No interruptions, cracking or hissing as with many other products common. I'm using the headset in the helmet and have problems making calls, navigation can hear announcements and music despite loud exhaust and wind noise. The battery life has exceeded my expectations with loose 12 hours! Therefore strong buy recommendation specifically for bikers. Those who come clear with in-ear headphones under the helmet, has a super convenient solution for Use Scooter!
