Im looking for great sounding closed cans that have great bass. I haven't been on these forums in over a year but the last headphone that were recommended to me were the Ultrasone 900's are they still the best for what im looking for or are there better now? Budget is $400
That's a tough one. From my experiences of closed headphones that I've owned or auditioned, my impressions of overall were sound quality are Edition 8> SRH940>D7000>D5000 = SRH840>DT250-250>K271>HD 25>MDR V6>DT770-80. Of these, D7000, D5000 and DT770-80 emphasize the bass. However the former two are not truly closed as sound leaks in & out like mad, and they are vastly overpriced for their flawed sound quality (recessed mids, hot treble). And the DT770-80 are the worst closed headphones that I have heard. Under $400, SRH840 & SRH940 are the winners by a mile imo, but they have *much* more neutral signatures. SRH840 slightly emphasize the mid-bass so they are more bass-heavy than the SRH940, but the merits of the 940 are that they remedy every imperfection of the SRH840 (slightly rounded off treble, an enclosed and dark sound). If overall sound quality is a bigger priority than the emphasized bass, I think that the best option would be to get the SRH940 and an inexpensive amp like the fiio that has bass boost.
