4. Experiment with BT Headset

The first two attempts were with Bluedio. Pairing did not work with two - tone with cable was not bad.
From a friend, I then get a Philips SHB7150 testing purposes. Here the BT connection worked easily and quickly.
After re-search and review of the reviews I have now opted for the ARCTIC P614BT. Delivered yesterday ordered-today. That's great!
Disturbing two things are my first noticed and therefore only 4 stars:
- Inclination of the earpieces, because not vertically movable. That's what I'm going to get used to but,
- No connection with cable, so only Bluetooth !!! (I have since about reading?) That's too bad.
NFC has initially does not work, but on BT immediately. NFC I will try again with other smartphone on occasion.
With the comfort and the sound I am very satisfied.
Very positive, however, I noticed that when soft music no "carrier frequency" can be heard. That was when Philips very annoying (so I would not recommend this).
Now, if the battery power has really as long as advertised, so that's then my strong buy recommendation.
