@hakuzenthe joyrooms are only slightly less detailed than the LZ-Z02A to the point where the joyroom comes out on top in detail retrieval on some tracks and the LZ-Z02A on others. In fact the difference is so small that I would have been happy taking the joyroom JR-E107 over the LZ-Z02A if i had a chance to try before buying.
EDIT
When you receive you joyrooms listen, do a comparison with both, listening to the track - stevie wonder - signed, sealed delivered,... At 8 seconds an instrument comes in from the left like a clarinet or something. On the joyrooms its sounds far more clearer and real than on the LZ-Z02A. Check it and I'd be interested to know your findings on this bit of micro detail.
woohoo! i'm enjoying the lz-z02a (less than 24 hours burn in), so will listen to and probably enjoy the joyroom jr-e107 as much =))
Stevie fan here, so will check that clarinet. read here about a 8KHz peak in the e107 (besides of its enhanced bass), while the trebles in z02a are more controlled than in z03a (no 6KHz peak). maybe that clarinet sound is around 8KHz. will also check their overall detail, and natural tone as well. thank you!
@hakuzen The most important thing for me is how comfortable are headphones
For example piston 2 and Dunu 900 don't fit well in my ear.
I said I wanted headphones for listening to rap and hip-hop.
I will use them to Xiaomi MI3 phone and computer.
I don't need a balanced sound , I need subwoofer =))) but a nice sound .
I can sacrifice the bass , if other headphones sounds better
just listened to some Eminem songs to compare sound between the cooking **** ue and lz-z02a.
**** has very good sub bass, but lot of rumble, reverberation (dunno if this will settle a bit after toasting). z02a has same extended sub bass, and maybe near presence to ****, but its faster, tighter, more controlled. i guess the kind of bass is a matter of preference (and both might need some more cooking; someone who has these iems for longer could confirm this).
**** cymbals sound splashy, very artificial (it seems is related to a 5-6KHz peak, read here). it also touches some loud vocals. i like z02a vocals (in general) and cymbals much more, and guess vocals are as important in rap/hip-hop than bass.
the drivers of the **** are very big (large and deep); although they are ergonomic, their size is in the limit (i have small ears). not as comfortable than tiny iems.
so i'd wait for more details about overall good sounding bass enhanced iems. you know about some of them now, but more are joining, as you can observe in headfiers' posts. bass enhance is easy to find in this price segment (natural or detailed treble is rarer to find in them). so take your time to decide based on detailed advice.
