Shure SE21DYBK+TW2-EFS

Shure SE21DYBK+TW2-EFS – second-generation SE215 earphones bundled with the wireless RMCE-TW2 adapter, in black finish. The bundle pairs the single dynamic SE215 driver, familiar from stage and everyday listening use, with a True Wireless adapter that connects through the MMCX connector in place of a standard cable. That setup keeps the same, well-known driver character without a wire running between the two earpieces, while still allowing a switch back to wired operation with a standard SE215 cable sold separately. Passive isolation up to 37 dB and a fit kit in three sizes handle outside noise both on the road and during rehearsals in a loud room.

Familiar sound signature, no cable between the earpieces

The RMCE-TW2 adapter carries the signal over Bluetooth 5.0 with support for aptX, AAC, and SBC codecs, preserving the SE215 driver's character known from the wired version, without a cable to route between the earpieces during stage movement or exercise. Role-switching lets you run a single earpiece on its own, which comes in handy for short calls or one-ear monitoring while working in the studio. Environment Mode brings in external microphones with a single touch, letting you talk to another musician without removing the earphones.

Battery that lasts a full day of rehearsals and travel

The adapter delivers up to 8 hours on a single charge, and the included charging case adds three more full cycles, for up to 32 hours total without access to an outlet. IPX4 water resistance protects the electronics from sweat and moisture during intense rehearsals or workouts, and auto power-on when removed from the case shortens setup time before playing. The ShurePlus PLAY app lets you adjust EQ to personal preference without altering the driver's factory tuning.
