just got kz castor bass version yesterday and the left sounded weaker than the right, so I'm returning them. They probably do have a quality issue (which I dont blame since its so cheap)

What i personally own: Kefine Klean (black version) fairly "safe" harman tuning sturdy metal shell tuning nozzles nice cable for the price nice case included Tangzu Wan'er S.G "meta" tuning for cheap (warm neutral) shell feels cheap and empty (it being transparent doesn't do it any favors) very basic accessories Truthear Zero:RED neutral tuning (crinacle target) decent quality shell terrible fit for a lot of people (huge nozzle) comes with an impedance adapter for more bass KZ Castor (Bass) actually has a bassy tuning has a bunch of dipswitches to tune it feels cheap (even cheaper than the tangzu wan'er sg) terrible stock cable bulky Moondrop Chu (first version) sound really nice didn't survive too long, oxidation issues If i had to keep just one: Kefine Klean Best accessories, quality feel, overall just a very nice deal

Look at KBears Rosefinch for a bass monster. QKZ x HBB is pretty bassy as well...but nothing to the level of the Rosefinch. KZ Castor Bass Edition (the one with switches) can't touch the Rosefinch for unapologetic bass either.

I just suggested for them to look at them. ive owned the Castor Bass...wasn't for me. It might be for themšŸ¤·šŸ»ā€ā™‚ļø Yeah...$30 is not a lot for some...but $30 is a lot of money for many. There is literally an IEM at every price point for everyone. I threw out possiblities at that price point. One person can listen to the Diablo and think these are basshead enough...when they likely should save up for the Scarlet Mini (tho that is RENT money or a month or twos worth if FOOD money)

You are definitely a bass head lol nothing's balanced about any of the ones you liked. You like bass. But you're used to muddy bass. Hence why you feel the treble is too much in most iems, coz they sound cleaner. But at the same time, you got the wrong ones. You should've gone for the Tangzu Wan'er SG2 Red Lion edition or the KZ castor bass or even the Kbear Rosefinch in the entry level iems. Also I don't mean to shit on you or Nothing earbuds but the price gap is massive, but more importantly the tuning is completely different, so even if they sound better, you still wouldn't have liked the chu 2. Takes the same time as typing this to do a quick search here in this sub before buying. This isn't even wired vs wireless. Good luck with your next purchase. Also, I'd recommend not using other stuff and just listening to the Chu 2 alone for a week or two. You're too used to muddy bass which you don't even know so it makes sense you find everything treble heavy and zero bass. It takes time for your ears to get accustomed to the new sound. Hopefully you'll love it and won't be able to go back to consumer crap after :3

I really liked the KZ Castor Bass as well, after using it for two weeks in a row it feels so weird going back to other iems. In the end the bass are a bit too dominant to my likings as the vocals are completely overwhelmed with bass. I switched to a clearer set. It's still the best for listening to techno

Well gk kunten is not what i would call bass iem, if you compare them to tws or most v stage headphone even to standard of iems.And dac plays a imp part as both amp and a playing higher resolution music but if you stream it wont make differnece ,unless you download song and use dsp bypass with tidal or hibi music so ot wont matter much but its better to have . For Iem there are better bass options like og castor, castor pro and other pricey ones. If between those both get kunten(get eartips cuz the stock ones ar bad,)

Well for instrumental music, I can say KKSV is very nice but the bass will feel thin, not meaty as castors since this will have lower subbass.

Well all rounder is but subjective but juzear defiant would be better as they have good bass and good treble extension, you can ask u/This_is_Realisticrab for more detail
