Review on 🎧 PSB M4U 4 High Definition In-Ear Monitors: Immerse in Arctic White sound experience by Lucia Brown

I love these headphones. The best I've ever heard. I only compared it to a few but a few observations: 1) Excellent transparency. 2) Goes well with foam. It took a while to figure out how to use it as it's open all year round but once you get the hang of it it's perfect. 3) Great bass. Deep and dense, without boom. I compared it to some other headphones I have. It's better than RBH EP3 which is excellent in its own way. The EP3 has even deeper and louder bass, but I like the PSB M4U 4 better, it just sounds more natural. I also have the 1More triple driver and the M4U is much better than this. RBH EP3 is also better than 1More Triple Driver. Obviously better than the Apple headphones that come with the phone. I like the PSB M4U 4 as well as the KEF M500 headphones. Both are smooth, natural, deep, balanced and clean. Great buy, especially at $115 for whites.
