Better than my Sony 7510's.
My Sony 7510 gave up its life after 20 + years of dedicated service. I ordered another pair online and was contacted by my sales representative, Yuval Fuchs. He suggested the Shure SRH440 as a more than suitable replacement for my dear departed Sony. I said, "Shure for mics, of course, but headphones?" Yuval assured me that the SRH440 was a more than competent replacement (and it was $39.00 cheaper than the Sony 7510 replacement to boot!).
Based on Yuval's recommendation and that ALONE, I ordered the Shure SRH440 (he has NEVER mislead me on anything before, so why should now be any different?).
When I received them I tried them immediately and BOY WAS I SURPRISED! I have a 50% hearing loss in each ear so I listen to things at a VERY loud volume (not bright I know with a hearing loss going into it).
The audio output on my computer and TV are at about 80% of maximum (which was fine for my Sony's, both the 7510 and a pair of 7506's that I also own).
When I plugged in the Shure SRH440, I almost got my head blown off! They were incredibly loud. I turned the overall audio output from 80% DOWN to 50% of total output (and bear in mind that this from a guy who LOVES his volume). I couldn't believe it.
Sure there are frequencies that I cannot hear due to my hearing deficiency, but those frequencies that I can hear were clear, resonant, present and loud. I heard much more intricacy than I did with the Sony 7510 (sorry to say Sony, but I still love you). I haven't tried them against the Sony 7506 yet, but I will.
Also, bear in mind that I have NEVER felt obliged to write a product review before (though I have bought hundreds of items over the years from Sweetwater) but this product (Shure SRH440) really shocked me (and I lived through the 60's - ha ha)!
In the end, neither Shure nor Yuval have let me down! Yuval I'm not surprised at, but the Shure SRH440 sure did prove to be a godsend. Thanks Yuval (ext.1367) for again being a good friend and a superlative sales representative. You do Sweetwater proud!!
