signs of a poor seal.
I think saying the M50 is the worst headphone you've ever heard is a bit extreme lol... I personally don't like them, but they are definitely not the worst I've heard
I listened to a friend's headphone a few days ago that sounded awful. I don't remember the brand but I had never heard of it. A small (almost on-ear), plasticy white little thingy with oval earcups, narrow headband and glossy panels on the earcups.
The sound was very tinny and colored. Ugh, I just tore them off after 5 seconds.
I've heard a lot of crappy earbuds and in-ears, but worst headphones I've heard? I'm trying really hard to think of something worse than the Beats Solos that an acquaintance let me listen to for a while. Pretty sure they were the HDs too. And they had no bass. Well, they had a lot of 100-200 hz, but I don't call that bass. My $40 Sennheiser eH 150s with loose earcups and distorted bass sounded better. My Koss PortaPros sounded better. I had some clip-ons that were nothing special, but at least they attempted to have a neutral sound. DT770 and M50? No contest. I've listened to a lot of headphones at Best Buy and the Apple Store and while a lot of them didn't sound good, they were still better than the Beats Solo. Wait...The Soul by Ludacris SL150/300 and the Sol Republic Tracks come close. The Tracks might actually be worse than the Beats. They're like the Beats but with even less treble. It's pretty close.
I agree with this. The UR-22v is actually much better. For $20 it's as good as it can get and actually has treble!
