Looking for a headset with good price-performance ratio for biking, jogging, hiking, and traveling I came across this product. The ultimate incentive to buy gave me the Möglichleit to be able to use the device even when the batteries and the plane. Ordered, received, unpacked> wow! First I noticed the great ear pads that rest over the whole area, on. Unlike my previous headset the SHB 9100 is much more comfortable to wear. Even otherwise the headset, because the bracket well padded, very comfortable to wear. The maintenance of the strap headphone is good, so that even when moving a tight fit is ensured. The sound is great, but very neutral. Those who like a bit bass-heavy listening, for which this product is definitely not. Whoever listens to his Smartphone music, can z.Bsp. about the "power amp" or similar Players Even optimize bass & treble. The battery life is as stated and perfectly adequate. The title control on the headset requires a bit of practice, then it is working fine. Calls to headset is good, but you have to remember this is the Micro realtiv far from the mouth. So when strong wind or high ambient noise levels, there are certainly better headset. Just great I find the twin solution with BT and Cable. With the cable the sound is a little better, I can still continue to listen if the accus are empty and I can use the headset also where wireless solutions not allowed (airplane, hospital ..) The BT-range I think, compared to other headsets , surprisingly large. As a single Kritkpunkt I've discovered that the large on / off button like to the headset when it is transported in a bag, there switch on independently by the possible external pressure.
Conclusion: Good workmanship, still very comfortable to wear tight fit, great sound and usable anywhere. Unrestricted buy recommendation.
