Svanar Wireless (open-box)

Sound is ok but they are very uncomfortable, cannot use after 5 minutes, my ears hurt!

In terms of sound quality, for a TWS it sounds amazing in the HIFI mode, but the ANC and transparency mode reduces the sound quality dramatically. The charging box and earphone are beautiful and solid, but both are quite big for doing exercise. The ambient noises also easily impact the sound quality in LDAC mode, resulting jitter and voice interruption. If you're not going to use it in gym, running, or a busy area, and you want to just enjoy listening your music and movie with great sound quality with wireless connection, it is the best choice, delivering the best sound quality of a TWS, even better than my previous Grado GT220.

I knew Im buying the best IEMs but open box so should expect it could be smth wrong. I have a feeling that right ear is not playing that clear as the left one. Overall Im happy anyway
