ELECOM True Wireless Earphones (Model: LBT-TWS17BK). Color: Black. ● Supports AAC codec for high-quality sound ● Semi-open type that doesn't put pressure on the ears and allows ambient sounds to be heard ● Small and lightweight design (approx. 3.3g per earbud) ● Low-latency mode ● Easy operation with touch sensors ● Auto-pairing supported ※ Connection is made to each earbud individually. I'm not good with technology and don't know how to reset it, so I haven't used it and have stored it in a dark place. It might be fixable if I can properly reset it. Instant purchase OK. Will ship with simple packaging. No returns accepted.
