I had a set on my xt660r they are very good quality and I am in the trade . Sound really nice not over loud just nice and deep with baffles in . I only took mine off 2 weeks ago (and was gutted ) as I have bad ears. I would not think twice of buying another pair if my ears were ok. Buy them you will not be disappointed. Ps one thing I would say to all riders use ear plugs from years of riding and then 2 years ago doing 2000 miles on an xt660x with aftermarket cans on in 3 days fecked up my ears for good. I now have bad tinnitus and any wind roar even with plugs in feels like hell. Trust me just google it how many bikers end up in trouble with there ears. It really is not worth it trust me the pain is not good.
