First impressions from using the headset were very positive: stylish, lightweight, comfortable, excellent sound. Though I have noted that the controls and operation are not so good. Volume control and the answer/end button work fine, but rewind works very rarely. The sensor simply does not recognize my double-tapping. Unfolding of the headset to turn it on was very nervous at first, because hinges look fragile. But this is not a problem, one month has passed and the hinges are still intact. There are other problems with the headset.
Headset periodically loses connection for 1-2 seconds. Sometimes the period is longer. Similar symptoms appear every time you turn on the headset, but they are held with greater frequency and duration - it is simply impossible to listen music the first two minutes after the pairing. So I just take off my headset on this time - and it's really annoying. At first I thought that the problem is with my phone, so I tested the headset with my wife's phone and my MacBook Pro - the problem still was there. The problem does not occur when you connect the Halo as regular headphones using the 3.5mm cable.
Another thing you should to consider is a velvet coating on the inner side of the Jabra. After a week of careful use this coating started peeling off near the hinges and on the sides of the headset. Small pieces of this material is gradually fall off, exposing the fabric material. Nice? Read more.
One of the biggest priorities for me was to use this headset as regular headphones with the 3.5mm cable. Yesterday I discovered that the connection between the Halo and the micro-USB connector doesn't feel quite right anymore. It is suffice to move a little bit my head and the sound disappears. But the biggest problem now is to charge the headset. I need to move connector slowly up/down and pray to put it in place.
Maybe I was not lucky to order a problematic item? I don't know. But I'll be happy to replace or repair it. And the biggest problem is that I can't find any service center of Jabra here in Ukraine, so I really do not know what to do.
