I've had an absolutely terrible time today.
First my SHR750DJ arrived broken. I opened the completely sealed box to see a piece of hinge rattling around inside the plastic bag, this makes me question Shures build quality and control. I then contacted Addicted to Audio were I made the purchase who told me they won't deal with returns I need to contact their Shure supplier for warranty replacement. So while I had them here I decided to give them a listen and the bass is terrible. there's no quantity what so ever compared to my now almost 'sold' XB500's, absolutely no buzz at all in comparasion. I'm running an LOD / rockboxed ipod Mini / E11 on EQ2 and the bass just distorts before reaching any pleasurable levels. Overall the sound is very good but nothing I would write home about... but bass? What bass.....
Shure boast these can handle extreme power without distortion, yet they pack up shop anything over 4.5/8 on the E11.
The XB500 easily chews the E11 all the way up to 7.5/8
I am that fed up with this Shure sale I am about two inches from simply throwing them in the bin. I have now repurchased another pair of XB500, which obliterate these in bass amount, the shure don't even come close, there's no rumble or pressure just a subtle bass amount. Sure..they sound a little better but they do not have a right to be in this club.
I recommend for bass heads do not purchase 750DJ it does not fit the requirements for this club and the plastic build is terrible / and the comfort issues lets not even go there..... Terrible!
