High-resolution earphones tuned exclusively for vocals and pianos

Aluminum and stainless steel are used in the housing to reduce sound leakage to the surroundings with excellent sound insulation.
The sound of each instrument is clearly conveyed with tuning suitable for vocal and piano performances.
Since the main unit is equipped with a microphone, it can also be used for online lessons.
※ There is the case that I cannot use it with some PCs. Thank you for your understanding.
