The TF10's are very v-shaped... they're horrible for analytical listening, but who does that out of an portable while walking around anyway! Since I'm into really hot treble with a punchy, but not overwhelming bottom end *COUGH COUGH CHRIS IS A GRADO WHORE*, it's really hard to find something akin to these, I hear the SM3's are good (kind of pricey), the W3's I listened to have too much bass mang! If you liek boom boom with all the quality there, it's good, I'm still suck on the UM3X series as an alternative if I ever lose these...
I find a nice balance is to own an ER4 and a TF10 at the same time... the treble of the TF10 can be a little aggressive since it's not a "polite" sounding can by any means... so I used to swap to ER4's when I would slip into "old man" mode. I have a pair reshelled by Fisher, I'm not associated with them, but as broke as I am, I won't hesitate to mail every single mid-tier to high end IEM I ever own to them for reshells. At the price they offer their stuff for and the back end support they offer after the sale, it's really a no brainer if you're looking to immortalize your favorite IEM's. Who said customer service is going out of style?
Talk to Raguvian about how much he's enjoying his, he might have some insight on your future situation haha!
Thanks for the compliments btw, I'm always here to serve the community, but lets allow folks to discuss the TF10 here
