I am very treble sensitive myself, probably the biggest reason that I tend to be a low volume listener, but I still have trouble calling the NT6 Pro a bright CIEM - hence hot treble. I guess it is a matter of prospective. I don't have the experience of hearing all the great CIEMs like average joe for perspective, but to me the NT6 Pro feels very neutral in signature with everything that I have paired it with. However, being painfully neutral, the NT6pro does't have the mid nor mid-bass bump to cover up its highs so they do come through with great clarity and detail. I think the NT6pro's secret sauce is its 5-way configuration allowing the BAs to focus on a smaller range for greater clarity and better blackness. However the low end goes really low with a lot of authority as well providing a very balanced sound with nothing getting in the way of anything else. If the sound is not there, there is just blackness unlike the bright IEMs that I have heard the just continue hissing at you without any bass to back up the sound. It is actually the treble extension that provides the rich 3d texturing to the bass that makes it so realistic rather than just being a bass fart. With a kick drum for example, using a well recorded source, it allows you to hear the pedal, the slap, the boom, the reverb, and the decay and even the stop if kicked again.
I wish there was an easy way for you to hear them yourself, you would see what I mean.
A week ago I wouldn't have agreed with you Barra, but after the 100 hour+ extra burn in of the Nt6 pros, I now do. I also wouldn't call them overly bright now. They were before. I was using the eq to bring down the aggressive, overpowering treble above 4kHz. Now, no eq. Complete change. Vocals have come out, far greater coherence is present.
Listening to anything I have, included poorly mastered or deliberately grainy and trebly recordings, I don't touch the eq. These are amazing IEMs. Mids are now great as well. I can't imagine people disliking them with the Hdp r10. This combo is fantastic. Insert all hyperbole possible about sound! I switched back to my midrange CIEMs and the difference was staggering. Bass extension, no comparison. Detail levels, soundstaging, realism and that musicality that keeps you listening, all no comparison. Isolation is also very good, better than my other acrylics.
Very happy with these! I imagine most people would be ecstatic with these. Unless you love warm. The bite and slam of these is addictive. Well done Hidition.
Thanks for the confirmation smithy, I was starting to wonder if I was all alone in my assessment or if my cables were making a difference given the constant cable changes from hidition.
I am really enjoying the x5. Too bad we are on opposite sides of the planet as I would love to compare it to your r10.
