As already mentioned, the shipment was repackaged in a sturdier box on the way.

The battery does not correspond to the description in the overview. The battery is bigger.

Still needs to be soldered in. But batteries are fine.

I will return with the review after use.

Correct voltage. I haven't used it yet.

Moldavia I didn't test

Good

Everything is fine. The headphones came to life. They turned out to be much larger than their relatives. I managed to squeeze in, but pay attention to the size.

After installation, bluetooth works for the third day, I’m happy with the purchase, I recommend it

In general, everything is fine. Satisfied with the product. Sends what it advertises. Thank you
