I feel a need to briefly give some comparisons. All listening through X Sabre 3 balanced > Charter oak PEQ-1 balanced > Headamp GSX Mini balanced 4-pin XLR > headphone.
HEKse vs Fostex TH900:
While Th900 a very fun v shaped dynamic listen, HEKse better on technicalities, timbre, natural sound. Bass more linear and excellent layering. Quantity less than Th900, but HEKse the more satisfying accurate listen. HEKse has plenty of treble with endless extension. But far cleaner than TH, which has a well known treble peak that’s unnatural and quite audible and frankly now after listening to HEKse for a year is unlistenable to me. Used to love Fostex before HEKse came along. Mids recessed on Th900 too. Obvious when comparing to HEKse.
HEKse vs Denon D9200:
The Denon HP sounds great, but HEKse has more and better bass. Hekse mids win here for detail retrieval. Denon ever so slightly drier sounding. Like treble on both. And both have ample treble, with some recordings bordering on bright. But neither strident, harsh, or fatiguing.
HEKse vs HE-R10P Stealth version 2:
Wanted to love the R10P. Especially for the exorbitant price tag. It’s a very good sounding closed back. But hasn’t got the chops that HEKse does in either mids or treble, R10P treble being a bit darker, and R10P bass while good in quantity just not as layered or articulate as HEkse. R10P was good and probably the best closed back I’ve heard, but was no match for tge open backed resolution monster HEKse
HEKSe vs Sony MDR-Z1R:
Sony had bigger fatter somewhat flabby or overhanging bass. No obvious bleed into mids. But mids on the Sony just missing something. Can’t articulate in words. And the treble on Sony is pulled back and while respectable in presence and extension was no match for HEKse.
Yes, I know all these comparisons were closed back. And yes, I didn’t comment on soundstage or image specificity because it was clear in each case that HEKse, being known to be one of the best open backs in the world, trounced each and every one of the above. The Fostex TH900 was the most fun and punchy dynamic listen, but the weird treble peak it has cannot be overlooked.
In conclusion, the HEKse has both U shaped fun factor with strong bass and treble tonality. Couple this with Susvara like technicalities and it is far and away my favorite headphone. And it takes very well to high end EQ. Another big plus for me.
Thanks for listening!
