Compatible Wireless Headset Battery

This Cameron Sino battery replaces the original power cell in Sennheiser IS, RI, RS, RR and Set series wireless headsets. It fits models including the IS 410, RI 410, RS 4200, RR 4200, Set 830, Set 840 and Set 900. The 150mAh capacity matches the factory specification for direct replacement.

Sustained Listening Performance

Pre-Installation Checks

Verify the exact model number printed inside the headset battery compartment against the compatibility list. Confirm the physical dimensions of 32.00 x 25.00 x 7.00mm match the available space. Ensure the connector polarity and style are identical to the original pack before fitting.

Questions about this item

Does the 150mAh cell get hot during all-day listening?

The 150mAh lithium cell runs at low current draw in these headsets, so it stays close to ambient temperature during continuous use.

What must I already own for this 32.00 x 25.00 x 7.00mm pack to work?

You need a compatible Sennheiser wireless headset such as the RS 4200, Set 840 or IS 410 that uses this exact form-factor battery.

Will it fit an older RS 420 or Set 830 TV unit I still use?

Yes — the pack is listed for RS 420, RS 4200 TV-2, Set 830 TV and Set 840-S, so those legacy models accept it directly.
