Average in all their features and they didn't sound good in phone calls but even more unacceptable in the way they hug the ear wing for the stability of the placement you expect for their type. And this happening only in the right ear, which means defective construction since I have three other pairs of wireless bluetooth earphones that have perfect stable placement. After a few months of use, they started to connect only one of the two each time despite my efforts to make them both work at the same time when I didn't want only one of the two to work. The other 3 pairs from other companies work flawlessly either with only one earbud with the other in the charging case or both simultaneously without ever causing connection problems.
