Its sound is on par with the Senn adapter, its just more practical this was as it spares the phones jack from strain having a huge and heavy 6 inch plugged directly into the headphone jack. I still love the headphones now even more since there isnt any more hissing sound :) Will definitely order from this company again and certainly recommend these here slippers! I ordered the midnight blue case, which is pictured as having a bright yellow top. I bought this to redo our 110"ish closet. Update we got some pictures back and I love this dress That being said, they came promptly, on the date promised. Cant complain. but will the sweat and get icky so far so good . I personally left the plastic doors off cause I didn?t like how they looked and it would be a bit of a nuisance to me.
