It is on-ear headphones, in the heading as well as in the listing of features, there has been a mistake.
The cons:
1) Small control buttons (on the right earphone), which make it inconvenient for stop/forward/rewind, as well as for call termination, although this is slightly prominent.
2) I have never seen protectors with so many audio holes on their surface. I hope this does not negatively affect the expected durability and functionality of the material due to friction.
3) They do not have a 3.5mm jack port, which many stores wrongly include in the specifications.
The neutrals:
1) There is a game button, which I do not use much space for, so I would not say that I am the right person to give an opinion.
2) The hearing protection cutter, which has 85 decibels, although a nice thought, may disappoint some. It is not fixed, it has an on-off function.
The pros:
1) They have the second best position out of all the ones I have tried (after the JVC HA-S20BT / 96 gr.) in terms of comfort. They also do not lose much grip.
2) In prolonged use (4 hours+), they do not tire or bother. Their cushions are quite soft and have a foam coating on the top of the headband. The adjustment of the headband from minimum to maximum extension has 9 gradations.
3) They work smoothly in GSM phone calls and Viber video calls.
4) Given the lack of Active Noise Cancellation, they perform quite well in passive isolation.
5) I do not know the battery capacity they have, but from 10-100% with a 20W type C charger, they take 70 minutes, which is fine. Also, their autonomy surprised me positively for an entry-level product.
6) Not at all for audiophiles, but okay sound for the economical price. The bass is clear and distinguishable, whether without an equalizer or with it set to flat. The Edifier Connect application from the Play Store has 1-2 additional settings.
7) Small, relatively lightweight (172 gr.), not bulky at all, and additionally, because they are adjustable in size, they fit comfortably in a waist bag if you don't have a case.
8) Good, immediate connectivity, and automatic disconnection after a period of non-use.
