For sale is a Tralucent Ref.1 but the right ear piece has no bass. I talked to Tralucent and they do not repair IEMs as old as the Ref. 1. Therefore, selling this IEM to another Ref.1 owner who might want a backup for their left ear piece. This sale really only will appeal to existing Ref. 1 owners who know they cannot get their IEMs repaired down the road. Or maybe there is some fun, clever and radical individual out there that wants to combine 2 different IEM ear pieces. The left ear piece is 100% functional. The right ear piece has treble and midrange, but there is no bass. Bon Appetit.
