They are a nice earbud, i bought them to try out and they are surprisingly well fitting (when you use the correct ear-cup), no chance of them falling out.
The box is the charger so the whole unit is quite handy to have.
When they arrived i could not charge them
and found that there is a small bit of tape protecting the contacts. Needs to be removed first
. But after that with a small bit of fiddling to get them into the correct positions, they charged no problem. The charger LED on the box turns white when they are fully charged, but will not change white it the contacts are not sitting properly in the box (another thing that took me a little while to figure out).
You also have to remove the right one first
from the charger otherwise they will misconnect. If you remove the left earpiece first, it can take up to a minute to reseat them properly and then remove them in the correct order.
The sound from them is very clear, there is no background noise, and not a great deal of bass. They are very decent for the price. Neither amazing nor bad, and are comfortable.
I tried them in headset mode once very briefly. When a call comes in, the voice (female) calls out the phone number that is ringing you can tap the button to stop it. There are other button commands (redial etc) but i never planned to use them as a headset, so did not.
I had to charge them with normal use after roughly 4-5 hours, even though it says in the packaging that it is 12 hours.
As soon as you place them in the charger, they disconnect, and reconnect as soon a you take them out. Also, if you place them in the box to charge, and the box is nearly out of charge, instead of disconnecting or charging, they will connect and drain themselves, so you must be careful that the box is fully charged.
They were up above $50 at one stage, which is the main reason i bought them at the $35 price. I have since given them away to a younger relative (by coercion, not choice
Cheaper here €19.40 https://www.joybuy.com/3298199.html
The last thing i bought from these, took less than 2 weeks if i remember correctly.
