Lanzeittest were excellent

I am a coach and coaching over the phone was August 2011 with exactly this headset. For this I use the part about 4 - 10 hours a day, 5 days a week.
My conclusion - after more than 2.5 years, the battery is still just as good as on the first day. The call quality is always excellent, better than my landline phone. Background noise is very well filtered out, especially when driving.
Of course, wind noise can be heard anyway and loud background noise coming through, the thing is not a miracle but a longtime, excellent companion, which survives sometimes a sit on or squeezing in your pocket without a murmur. After now two years and 8 months a loose connection is created during charging. After I had charged it partly twice daily wear, I can get over, I've ordered the same thing at once and my son is looking forward to be able to use the old continued, -)
