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

I've had these headphones for over 4 years. My only complaint is that they are not wireless. However, the Lightning adapter solves the connection problem. In terms of sound, the most important thing is to find the right foam attachment and to position the earplug correctly. If you're an educated, knowledgeable, and experienced music lover, you might have reasonable questions (after all, what's the use of having experience in any field if not to criticize something), but even more discerning, if unspecialized, listeners will love the sound of the PSB MU4. I can't wait to try PSB's wireless iterations.
