Here's my feedback on the headset:
+ Deep bass sound because the sound body is also quite large. Ups also come across well
+ Tragekonfort is good. Had the headphones while running for 2 hours and had no complaints. The headset also does not sit firmly on the head but firmly. Even when the headset has good fitness forgotten, despite many movements
+ Volume buttons on the headphones, the volume can also be adjusted while running without the MP3 player to dig out of his pocket. Very practical: The songs were weitergespult
+ NFC: The Bluetooth pairing went super fast by NFC and without problems. Also for devices without NFC, it was relatively easy to pair the headset.
+ Long battery life
- After 4 hours of comfort to read
All that can do nothing wrong with a purchase are looking for a sound good Bluetooth headset for sports area here. Also suitable for the private sector, but I would use the headset for more than 4 hours since the bracket but then suppressed, but I had the earlier much earlier in my headphones.
