Excellent, but...
I only use it for telephoning, and the more time passes, the more I love it! Especially when I see the others that you have to stick in your ears, that fall out, roll under the sideboard and that you don't know how to catch without pressing a button.
First the "but..." :
- Confusion with long hair: impractical without ponytail, bun, pigtails...
- No possibility to put the head backwards
- No possibility to put a bonnet (I don't call "bonnet" something that doesn't cover the ears and the neck)
Otherwise :
- Excellent fit on the head, very easy and quick to put on.
- Very comfortable, I phone for hours without tiring, and often wear them preventively so I can answer without having to let go of what I am doing.
- Very good range (my home/workshop is not very large, but quite enclosed and cluttered with metal objects), I have never had a loss of signal.
- Very good ergonomics, pdf manual in French (manufacturer's website) complete and clear, no need for an app on the smartphone, and real buttons practical to use.
- Very good autonomy, fast and practical charge (magnetic plug).
- very effective anti-noise microphone, my correspondent hears almost nothing of what is happening around me.
- Good audio quality (listening) for phone calls.
- And the best for the end: choice of language for voice messages, if you're bored of English you can also choose Chinese, Japanese and Korean... top, no?
note: on my smartphone the volume control was not very satisfactory, I was able to give back to the headphones the independence of their volume control (by default the buttons control the phone volume), with the following manipulation: System > Developer option > Disable absolute volume. This is an Android option for bluetooth headphones, not specific to them.
