[QUOTE="Guest, post: 93971"] I'm currently using a B&Z but have used the Rooster Booster. Like LT said pretty much the same sound wise. One thing to be sure of if your going to use an external speaker only on a GPX4500/4800/5000 (no aftermarket booster) is to make sure it's wired correctly. You need a TRS plug wired to tip & ring only - nothing to sleeve. This configuration will trip the battery internal amp for external speaker use. Normally wired headphones won't trip the internal amp nor will aftermarket boosters. The batteries amp should only be required to provide more oomph for an external speaker & you shouldn't really need it for headphones - in fact it could damage your hearing. The reason the boosters are wired not to trip the batteries internal amp is so you aren't amplifying into another amplifier which would most likely cause distortion. There is info on wiring external speakers (& I guess headphones if you want to boost them) on page 13 of the GPX5000/4800 user manual. I have found that the aftermarket boosters are better than the batteries internal amplifier when using external speaker/s. [/QUOTE]
