These are Technics' first wireless earbuds. The design is a bit clunky, but the sound quality from the 10mm drivers is excellent. Although it's an older model, it can still be used actively. Music playback, noise canceling, and other functions work well. Due to initial manufacturing defects in the first production run, I had to send them in for repair, so the (M) ear tips are the later, defect-corrected version. There is no box or spare ear tips.
