Three months in and the Monster still works like day one. I use it daily and the ultra-lightweight comfortable ear-hook fit has held up perfectly — no wear, no issues, no regrets. It's the kind of headphones that makes you wonder why you didn't buy it sooner. At about $27, it's comfortably the best value headphones I've bought this year, and I'd buy it again in a heartbeat.
I've tried similar headphones from three other brands and this one wins hands down. The IPX5 water resistant - with IPX5 is the deciding factor.
Upgraded from cheaper headphones and the difference is night and day. The ultra-lightweight comfortable ear-hook fit on the Monster is in another league.
I do way too much research before buying anything and the Monster checked every box. The crystal-clear calls - featuring advanced is solid, the price is fair, and it looks great too.
Arrived fast and works perfectly. The advanced bluetooth 6.0 - powered by is a nice bonus.
Not gonna lie, I was skeptical about ordering the Monster online. But it genuinely exceeded my expectations — the long battery life - get 8 hours of playtime works flawlessly.
Idk, maybe I expected too much. The Monster is decent and the ultra-lightweight comfortable ear-hook fit works as described, but nothing wowed me. Three stars feels fair.
Great value at around $27. Solid build quality too.
