I went to RMAF last year specifically to listen to the iSine20. It blew me away, and I tested them using my standard S7 phone. No EQ.
It hurt to spend that much money on 'just earbuds' but I ordered them online within an hour of getting home. Zero buyers remorse once I spent 5 minutes with them at home.
Of the short list of material things that have improved my life, these are absolutely on that short list. I've spent many hours over the last year listening to music, new and old, even stuff that I'd never listen to normally. These things do something magic and they infuse the sound with a sense of purpose and character that I feel but find difficult to describe but obvious in its presentation. As examples, Stone Coyotes Live at the Iron Horse sounds alive with the iSines, while sounding like merely a live recording through any of my other earphones. Same for Stacie Collins. (I realize these are far from the last word in recording quality, but the sentiment stands)
Can you use them for metal? Absolutely!! I do.
Can you use them for <insert genre here>? Absolutely!!
I've found that there is a point in audio reproduction where improvements in the gear only serves to illustrate shortcomings in the recordings. I've listened to music on my rig that was enjoyable, while on a much more expensive and higher quality rig that same recording sounded like dog poo and was painful. The iSines don't do that; so far they've occupied a sweet spot where they make great recordings sounds great, and allow mediocre recordings to punch above their weight.
I feel like I'm wandering, so I'll close with I've never EQ'd them, but maybe someday I'll experiment. After wandering the floors of RMAF, I feel like these things provide me witht the sound of many of those rooms everywhere I go. At work, doing the dishes, typing this post.
Guys, would an isine 10 with standard cable be good for metal ( death, doom etc..) ?? Will use with either a Questyle qp1r or opus #1s
I don't really like to EQ but will if needed.. would you say the 10s are more vshaped to the 20? Thanks!
