I sold my Denon AH-D5000s and replaced them with a pair of Shure SRH940s. Bass extension on Denon's was good but there was too much bass boost. The music was more prominent than the vocals.
I started searching. I had previously owned the AKG701 and liked them but the bass extension was not low enough for me plus I needed to switch to closed backs to appease the wife. I was looking at graphs from different sites and compared to the different sets I had owned. I found the graphs of the AKG701s and the Shure SRH 940s similar but not the same. Bass on the SRH 940 are well extended like that of the Denon AH-D5000s but not as much boost. The vocals were more prominent on the SRH940 like that of the AKG701. The result was a closed back headphone with the sound I liked.
There is definitely a break in period required for the Shure SRH940 of about 20 hours. When I first unpacked the 940s, I thought I had made a mistake as the vocals appeared shrill and not very enjoyable to listen to. The longer I listened the better they got.
So far for me, they are the best I have had. Sound is priority over looks for me. It doesn't have to expensive to be good.
