Engineered for Motorola R7, R7A, and MXP600 radios, this headset keeps voice traffic clear while staying out of sight, which makes it a practical custom covert radio earpiece for surveillance, security, and plainclothes teams. The modular build lets you specify tubing, earbud fit, and connector options, so each unit arrives as a tailored custom acoustic tube earpiece that stays comfortable through long shifts.
The PTE-880 is built around a moving coil dynamic transducer and a low-profile acoustic tube, so radio traffic stays clear without drawing attention. Power-Time lists the following key features for this model.

The product page names law enforcement, security personnel, covert operations, surveillance, tactical operations, public safety, and emergency response among the settings this headset is made for. Because the acoustic tube keeps the earpiece low-profile while preserving situational awareness, it suits both plainclothes and uniformed teams that need to hear traffic clearly in noisy surroundings.
Power-Time also offers bone conduction headsets for use with respirators or helmets, headband and helmet headsets for high-noise environments, throat microphone headsets for tactical operations, and fully custom solutions, drawing on more than 20 years of audio accessory experience.
