Is there a difference in tuning between the black and the silver one Jasper? I personally prefer a sound signature with more lows/mids and less treble, to make it easier for long term listening. The Jasper looks very interesting to me right now since I like its form factor and the fact that it is a single dynamic driver (which I prefer for timbre and coherency). From the reviews I've seen, it does seem to have a natural tonality with slightly more bass than neutral. Looking at the frequency response curve, the Jasper might have a bit more treble than I prefer, but I could always EQ that down if it bothers me.
How do you find the mids and vocals on the Jasper - are they ahead of the treble? Also, how is the bass? Does it have good rumble and natural tonality/texture? Also, how is the isolation and comfort? Thanks!
Final silver and black models have the same tuning. Prototypes have different tunings. Final one is natural-neutral, the second tuning was more fun V-shaped with a bigger mid bass and brighter, more energetic treble. I like the final one more, safer, vocals are more romantic, presentation is warmer, yet the background is clearer.
Lows aren't huge in quantity, but have great quality. Attack is well defined, decay is natural, texture is good (maybe even one of the best in their price range, for sure noticable better than KXXS). There is good dynamic and - when songs call for it - Jaspers hits with a nice rumble and authority. In many songs they could sound quite big and bold thanks to their great lows.
Lower mids have a bit of added warmth from lows and instruments have nice tonality, but aren't pushed upfront. Male vocals are natural, clear, detailed. Female ones are a bit more forward and lively, yet smooth and natural, not shouty. Never sound disconnected.
Highs are quite safe, cymbals won't hit you with a painful crash for sure. Smooth, yet lively. The more I listen to them, the more I like their highs' extension. Lower treble is a good step behind higher pitched female vocals. I like them with Acoustune AET07a and Azla Sedna Short, but for your preferences JVC Spiral Dots could be better (highs are even smoother, lows are fuller and soundstage stay nice and airy).
Comfort is very good and most users shouldn't have a problem with wearing them easly. Shells are very well made and have some weight (more than Falcon-C, lighter than ikko OH10), but aren't too heavy in the ears. Isolation is quite standard for a single DD model with a small metal shells -average with silicon tips, bit better with foams.
If it helps for test platform I use:
