harsh sound

I ordered the headset for the gym. Pairing with my OnePlus One ran smoothly and I could hear during workouts without problems Music. The sound, however, is absolutely bad. Bass do not exist anymore and the rest sounds more discordant. The comfort is modest, since in spite of the extra-Bügelchen press the earpieces a little. The housing is relatively far away from the ear. You see with this headset therefore made a little funny.

Positives:
- Battery power
- Pairing is easy
- Bluetooth connection without significant dropouts

Neutral:
- Comfort

Negatives:
- Sound very bad

Ultimately, the advantage of wireless music transmission by the absolutely poor sound is ruined. That you for the money you can not expect much, I knew, but that it would be so bad. I use again my old wired earphones a Japanese brand manufacturer.
