Just wanted to say - those buying a Piston 2 should really be careful to avoid counterfeits. Just got a message from someone who got one and is disappointed with the sound. Turned out it cost $12 and is fake. The Piston 2 costs $15-16 in China, so it shouldn't be less than $20 stateside. Also, it only comes in one color - gold - despite what Amazon's mess of a product listing seems to indicate.
What would be natural upgrade to quite old Hifiman RE ZERO? I love that quality, extended highs, resolution, crisp sound, clarity, upfront vocals without added thickness etc.
I would like even better dynamics and little more bass ( must be great quality, dont like midbass bloat)
I bet many users had RE ZERO - where to search something similiar but better? Im thinking only about universal iems. Cant tell price but it would be up to 250-300 USD and I could buy used ones.
My Dac is LG G2 and Im waiting for Cayin C5.
Aside from the RE-400 already mentioned, in that price range the TDK BA200 might be a good option for a hair more bass (if you can find one). I briefly compared it to the RE-400 here: http://theheadphonelist.com/headphone_review/tdk-ba200/ . Has a touch more low end and treble compared to HiFiMan sets, but not enough to throw off the tonality or sacrifice midrange quality.
Do you have a written comparison between the Inear SD2 and Noble 4s? I was wondering which of the two has better sub bass extension, treble extension, and more neutral presentation overall.
I have a feeling that I should've opted for the SD2 as my reference IEM...
I don't have a full comparison anywhere, but the SD-2 is actually warmer than what I consider neutral while the Noble 4 is pretty close. The StageDiver has very linear bass, no way to improve on the extension there, or up top for that matter. It just has a bit less treble energy than the Noble or an Ety or something. The Noble dips down a little in the subbass, but not significantly.
