TF10: Distant midrange made music sound poor for any genre I listened to except your electronic/trance type of music. Felt maligned within my collection once I got the JH13, so sold it off. Fit was perfect for me. Bass and treble are very nice, however, once I got a taste of the JH13 the TF10's treble felt quite unbearable grainy and 'in your face', which made the lack of extension compared to the JH13 much more noticeable.
IE8: Mid bass bloat. Midrange veil. Slow bass. Made music sound good to me for only hip-hop genres where bass beats are simple and slow. Horribly overpriced (in Australia). Did not worthy of it's premium price tag and it felt like nothing more than a refined CX 300 - II that I had lying around. Sold it off at some point.
Atrio M5: Shoddy build quality put me off this. The fact that when I made a warranty claim a few months after I bought these FutureSonics sent me non-working replacement pair. It ultimately put me off this and I got a refund for them. Somewhat similar sound signature as the IE8 without the midbass bloat, which is refreshing. Midrange was distant. Treble on the MG7 was much improved from the v2 drivers. Would of kept them if the build quality wasn't so crap. Overall much better value for money than the IE8.
SE530: Bass is a little polite and does not have too much impact. Sweet midrange. Treble is also rolled off a little bit and in the background a bit, which doesn't bother me a whole lot. A better all rounder for me and excels fantastically with genres like rock. Bass gained more impact or the sound as a whole felt more full once I had these turned into a custom due to the shoddy cables of the SE530 fell apart. Was actually very lucky to have a friend generously give me the SE530 drivers for free so I could turn them into a custom. Still have happily to this day.
JH13 Pro: Best sounding thing I have ever owned. Extension is fantastic in both ends of the spectrum. Only complaints would be the usual lack of depth and width in the soundstage is apparent as would be the case with any iem. Surprising synergizes well with any genre I throw at it, unlike all other iems I have ever owned that sound good for only some genres and not others. Doesn't have much of a unique sound signature due to it's very linear nature, except for perhaps I tiny bump in the 50-60hz range to give a less sterile sound. Only complaint would be that customs can get a little obtrusive within the ears at times and my ears can create ear wax in protest of having something crammed deep in there, but is common to all customs. Another complaint would be that due to the very linear nature of these iems they can get a little boring if you feel like to have a lot of bass impact (talking 'doof-doof' subwoofer) with some bass heavy song, or won't give you overly intimate vocals and guitar riffs the SE530 likes to give. Sometimes I need to jump down to lower iems just so I can remember and enjoy what extra clarity, details and extension I am paying for in the JH13, because your mind really does get used to it after a while and the initial wow factor fades.
