I think these are very good earphones, but the sound depth was too heavy for me. I mostly use lighter earphones, and I didn't use these very often. However, I dropped the left earbud when I took them outside and it got scratched. The scratch is not very noticeable, but please refrain from purchasing if you are concerned. The size M earpieces will be disinfected and shipped. The other size earpieces are unused. *Charging cable is not included. Wireless earphones that achieve high-quality sound and a comfortable fit. - Brand: Technics - Model Name: AZ60M2 - Earpiece Sizes: XS1, XS2, S1, S2, M, L, XL - Type: Wireless Earphones Thank you for viewing.
