Review on 🎧 Enhanced Plugfones Basic Pro: Wireless Bluetooth In-Ear Earplug Earbuds - Efficient Noise Reduction Headphones with Isolated Mic and Controls (Blue & Yellow) by William Turner

Much better built than the Liberator. The mic is built into the controls, which was a big problem for the Liberator as it stuck out like a thumb for people trying to hide the fact that they were using headphones (plus the mic is the first point to look at Liberators fail). Unfortunately the sound quality is not that good. Bass is lacking, but for people working in noisy environments this is really the only choice, with the exception of bone conduction headphones, which sound even worse than these. They're decent and cost $50. Liberators are too fragile for $99, these are a lot springier.
