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

I've used them on two long flights across the Atlantic recently and have found these monitors to sound and feel great. I bought these to replace my old Bose over-ear noise-cancelling headphones that I used primarily for flying, but they started to sound horrible and had intermittent feedback in one ear. I was worried the PSBs would let in too much aircraft noise, but to be honest they were a lot quieter than the Bose. I also like the small profile and carrying case of these PSBs. It's also easy to travel with. Good product.
