KZ ZS5v1 > 1More Triple > KZ ZS6 > KZ ZST > KZ ATR > Tennmak Pro > Tennmak Piano > KZ ATE
ZS5v1 on top. I wish they hadn't changed them because I'm wondering if I'll have a hard time finding anything under $200 that will compete with them and I'm afraid of losing them. The 1More Triple's were not worth the $100 and are lacking in soundstage, but are very similar to the ZS5v1's in sound signature. ZS5's have a larger soundstage and better sub bass reproduction as well as a more crisp sound that isn't sibilant in any sense.
Bold statement honestly. I get why people like ZS5v1 but they aren't untouchable. For example, I prefer Sony MH1c (<15$) by a small margin. Step up a bit and you get a very clear upgrade for around 35$ on sale - Auglamour RT-1 does everything better than ZS5 (except the sound stage where they are similar). This is not even taking into account accessories, build quality, comfort, isolation, design... Haven't heard iBasso IT01 which is probably an even bigger upgrade and I can only imagine what 200$ gets you today.
On the other hand, budget earbuds are winners for pure sound quality, a 10$ EMX500 gets you a long way towards musical bliss, in quiet environments though.
It's kinda dangerous to speak unfavorably about KZ's top dog here - just keep in mind that this is a personal opinion and not an attempt to start wars. KZ has yet to really impress me and I am looking forward to it.
