I bought some MH334s about 3 weeks ago. They are stunning. No other word for it. Proper HiFi by any standard.
If you're a headbanger; In Silico by Pendulum absolutely stomps. The sub-bass on Wet and Rusting by Menomena equals that of the subs on my main HiFi, it's eerie - you can almost feel it in your chest. Drums are fast and punchy - snares almost make you blink and cymbals shimmer and resonate forever. Then the resolution, it is mind boggling. Lyrics of songs I've pondered for decades are suddenly writ clear, the foot pedals on Ben Fold's piano are almost annoying!
I'm so impressed I don't care that one of them doesn't fit quite so well (Jaben HK have been totally cool and will send them back for a remould) - what I'm not happy about is they'll be gone for a few weeks - my backup Shure 535s just feel like a big flat let-down in comparison.
Again, so impressed am I that I tried another cable - the FitEar ISilver. I've written on it elsewhere here, but it just gives a bit more of everything; making an incredible product even better.
Expensive yes, but truly the best bang-for-buck bit of HiFi I've ever bought in my 30 year HiFi hobby. If you're teetering on the edge, worrying about potential buyer's remorse, don't...
