I have several headphones including Sennheiser HD58 Jubilee Sennheiser HD 600 and Grado SR80e and Philips Fidelio X2/27 and these sounds better to me than all of them and great detail. For $109 I doubt you can find a better headphone. Also the older HE400se had a cable that people said was crappy but they replaced the old silver flimsy cable with a better cable.
More detailed and more enjoyable than my Grado 125e and Sennheiser 600 with Cardas wiring.
Previous headphones/headset were a gaming/ham radio headset that was great for those purposes, but left something to be desired for music. The HE400se headphones sound detailed, transparent and natural when coupled with a Schiit Hel 2 DAC/amp. Even gaming sounds better!
