The Arrowmax SL24C-35L is a listen-only covert earpiece with an in-ear balanced armature speaker, ear guard fit, and a 3.5mm connection for RSM and PTT gear. Buyers report crisp voice clarity and lightweight comfort, but some mention price sensitivity, fit variability, and limited reach depending on how you route the 24-inch cable. If you need a discreet, stable earpiece for routine radio use, it can be a solid option, especially if you’re able to get the ear tip fit right.
The BCT22-K2 is a clear-coil 2-wire surveillance-style earpiece with an in-ear tube, push-to-talk lapel/collar mic, and a 2-pin connector designed for select Kenwood, BaoFeng/BTECH, and NEXEDGE/NXDN/DMR compatible models. It’s a practical choice for hands-free radio use, especially in higher-noise environments, with the main tradeoff being a bulkier mic/overall profile versus some slimmer earpieces.
