轉接套件 - 3.5mm 轉 ElectraStim 標準插座（單線）

Wasn't sure my old TENS box would play nice with these, but the 3.5mm plug seats firmly with no wiggle. Now I can run everything off one power unit instead of buying a second setup.

Finally, a way to bridge my old TENS unit to these electrodes without hunting for a proprietary box. The single cable feels sturdy and the fit into the 3.5mm socket is snug, no crackling or loose connection during use.

It does exactly what it says—plugs my existing 3.5mm box straight into the ElectraStim leads without any fiddly adapters or signal loss. The single cable is sturdy enough for regular use, though I wish it were a few inches longer for easier positioning.
