I am very pleasantly surprised, for such a price it is unexpectedly good. In terms of sound, it's excellent. For earbuds, the sound is good. My phone supports LDAC, no issues. Compared it with my wife's iPhone, the Chinese ones win in sound, and by such a large margin. The microphone is excellent, the interlocutor hears and hears well, even while riding a bicycle. They fit perfectly in my ears. If anyone is expecting gorgeous bucks like from in-ear headphones, don't expect it. On my dunu alpha through 4.4 and the amplifier, there is also no bass in the head, a feature of the design. However, you will be able to fully enjoy the instrumental, vocals, and overall flat bass. I haven't tried cheap Chinese ears before, but I highly recommend these!! !
