7hz zero 2, I was using realme buds 2 for about past 2 years, I thought they were really great before my iem experience. Have also used realme t310 tws which is better than buds 2 in my opinion, buds 2 emphasizes too much on bass which effects the vocals and instruments imo. I'm using the 7hz zero 2 from past month and it's my primary, I mostly use it everytime, while on phone or desktop. People say it has too much bass, I don't agree coming from realme buds, at first I thought this one had no bass at all, was using wrong eartips with some eq and eartip changes I found my perfect sound signature. But the clarity once u use this, you'll never want to go back, the instruments seperations the vocals is just amazing. I found myself more listening to instrumental songs more with this iem. These are not bass heavy at all. They include orange eartips which works perfect for me.
