I bought these as an entry level studio headphones. I was hoping for Shure's legendary SM58 type of quality and here's what my impression is.
The sound quality is perfect for my amateur purposes. I use it as a monitor set for playing bass guitar, midi instruments and vocals.
The comfort is great. Good padding on the right places, covers the entire ear and very lightweight construction.
The cable is long enough and is good quality as well. However the 6.35 jack adapter could be better. It's a screw-on sullution and therefore can't really be used on other 3.5mm jacks. Not a big deal but I like universal solutions.
What's my biggest concern about these headphones is the build quality. The body is made of cheap plastic. Only time will tell how long the pivoting joints will last. Unfortunatelly that's the most vulnerable point of all headphones and having broken three already I'm a bit dissapointed to see Shure's product this flimsy.
Overall, good headphones and definitely serves the purpose.
