Hi Nikolai,

Thanks! I refrain from codecs because they, quite frankly, don't matter as much for the sound quality in this segment as the tuning of the earphones themselves. I have some AptX-supported earphones that don't sound better than SBC earphones.

I actually wrote an extensive review on the Ytom T1, which is also called Wavefun X-Pods 3. It's pretty amazing for the price — one of the best sounding TWS under $50.
