On the several that we currently have deployed, transmitted sound is great and the speaker, with 1W stamped on the back of it, sounds good. We had two bad out of the last batch of five. Both were microphone issues. With the first one, I couldn't get the microphone to work until I plugged in an external speaker mic. Then, I unplugged it and the microphone worked but would buzz when the case was flexed or the radio when shaken while transmitting. The second one acted the same way out of the box. Both work fine with external speaker mic. Those were the only two out of any that we purchase that were bad but make sure you check them over carefully for that specific issue. I suggest micing up and shaking the radio around and tap it while transmitting to observe if the microphone cuts in and out. The board is tightly fitted in the case, so, as long as it doesn't do it straight from the factory, I don't think it will be a problem with the other radios in the future.
