Yh you are right mate,Thanks I'll request a refund next time. it's too late now... Do you know of any iem with more sub bass than the zircon?

Contacted once, issued me a refund. Not done it the other times...

Hi,   I have the rock zircon iem and love the sound signature especially the bass, but durability has been a problem (each pair dying in 2 months).   Can anyone reccommend an iem that is more BASSY (SUB-BASS) and more durable?   Thanks!

Thanks for the reply, do the iems you've mentioned have more bass than the zircons and which is the basiest and most durable?

Hi, was just wondering if somebody could help me out. I'm a huge rock zircon fan due to their incredible bass and sound signature. But I'm into my 4th pair due to them constantly breaking.. Was just wondering if somebody could reccommend anything with same amount or even more bass and similar...

I love the sound signature of the rock zircon, anybody know any with a similar sound signature (maybe even bassier) for $100 or less?

The ZS1 i have also had less bass than my xiaomi hybrids. Found out that it was due to the gold nozzles and crossover being removed. Hope they haven't done anything similar with the ED9's!!

Great :( The time I buy the ZS1, they change it! I wonder if anyone sells the old version? 

How do these compare to the xiaomi hybrids?

Had a similar issue with my KZ ZS1, was expecting incredible bass, but was nothing extraordinary and looser than the bass on my xiaomi hybrids which are in now way bass heavy IEMs. Where did you buy it from, I ordered mine...

Hi, asked this question previosuly with no response, was just wondering how the bass on the zs1 compare with the xiaomi hybrid or piston 2, as after comparing my zs1 with my xiaomi hybrids, impact is about the same and not as tight. Is this how its meant to be? Thanks

Has anybody tried the xiaomi hybrid how fo they compare bass wise to the zs1??? Thanks

Just tried the wide tips provided stock. Bass does not seem much better than my xiomi hybrids, does anyone have both and can compare or maybe even to the piston 2?

Recieved my Zs1 IEMs a few days back and was dissappointed to hear that the bass was nothing exceptional and very similar to my xiaomi hybrids. Overall nice sounding earphone but was expecting much more from the bass side, am I missing something?

Anybody bought the zs2 would love to know how they compare with the zs1? Thanks
