I bought two of these to use with my T460 radios. The description says it enables "hands free" communication and it's only compatible with VOX-enabled radios. I understood this to mean I can turn on VOX, pin this accessory to my lapel, and transmit communications by simply talking into this accessory. However, that is NOT something this accessory enables you to do. If you enable VOX, you must still speak into the RADIO MIC to initiate transmission. The accessory mic is NOT sound activated. Worse still, when you push the PTT button on this accessory, it automatically turns off VOX. In short, this accessory is NOT VOX CAPABLE. You MUST push the external PTT button on this accessory to activate its microphone. So this part of the description is extremely misleading: "With Motorola's 53724 Remote Speaker with Push-to-Talk Microphone, you can talk on your two-way radio hands free." This is technically true, but only if you duct tape your radio to your face and speak into the radio mic, whilst this accessory plays the role of an external SPEAKER ONLY. And if you accidentally push the PTT button on the accessory (which, again, will automatically disable VOX), you will need to un-duct-tape the radio from your face, cycle through the menu options to re-enable VOX, and then re-duct-tape it to your face. And you'll need to accomplish this using only your feet, otherwise it's not a true "hands free" experience. Also, this accessory has a simple PTT button, which means it does not support the dual-power transmission that radios like the T460 offer via their 2-level PTT buttons. In other words, this accessory is not "PTT Power Boost" capable. Lastly, I will caution you about mounting this accessory too close to your ear (e.g., your lapel). If someone initiates the Emergency Alert Button found on many Motorola radios, this accessory will automatically play a distress tone (think of it like a really annoying ringtone) AT FULL VOLUME FOR 8 SECONDS. Yes, it will automatically override your volume setting. It will then transmit an additional 22 seconds of the Emergency Alert Button presser's voice (more specifically, any sounds that are picked up by the presser's radio mic, as it automatically goes into a VOX-enabled state for those 22 seconds). Imagine this: you and a friend are out camping/hiking/hunting/whatever. You've got your fancy new external speaker/mic mounted on your backpack strap, just below your ear. Volume is at a comfortable 25%. Your friend gets injured and presses the Emergency Alert Button for 3 seconds. After a deafening 8 seconds of beeping, your accessory will continue to emit your friend's voice (presumably groaning, screaming, cursing, etc.) AT FULL VOLUME for 22 seconds. Hopefully they have time to read off some GPS coordinates to you, because now you'll need to home in on their location by listening for screams with your 1 remaining functional ear. To reduce this risk, consider mounting the accessory further from your ear, such that your comfortable volume setting is closer to MAX volume. Lastly, I'll mention that this accessory is roughly 19 inches long in its un-stretched state. This is the approximate length needed to go from a belt-mounted radio to a lapel, without stretching, on an average man's torso. If you're much shorter, you'll have some slack cord to address, e.g., by mounting the radio on the opposite hip and running the cord diagonally across your torso (or rubber banding some cord around your belt clip, as shown in pic and explained below). Conversely, if you're much taller, your radio might need to be belt-mounted directly under this speaker accessory, and you'll need to anchor the cord to your torso (shirt, backpack straps, etc.), otherwise the stretched cord will either pull itself out of the radio or pull the external speaker off of whatever you have it clipped to. If you have cord slack to spare, consider anchoring the cord to the radio by wrapping it under the belt clip and securing with tape, rubber bands, etc. This will help prevent cord tension from accidentally unplugging the external speaker accessory. How you accomplish this will vary, of course, depending on your radio. BONUS TIP: Since the external mic isn't centered in the plastic housing, mounting it on your RIGHT side will actually put the mic about an inch closer to your mouth. Ultimately, I have rated this three stars, because despite the aforementioned caveats and the lack of truly handsfree VOX support, it is ostensibly a quality product that serves its actual intended purpose. I try really hard to provide product reviews that are as informative as possible, so if you found this review helpful, I would really appreciate it if you could click or tap that "Helpful" button. Thank you!
