Do I need any other IEMs?

So, I'm not a reviewer at all, but since these IEMs have only 1 review here, which is ridiculous, I'm gonna throw my two cents in. Maybe it will convince a few more people to give these a try.

First of all, the only other IEMs in my collection are Blon BL01, Blon BL03, Trinity Audio Vyrus V2, Geek Wold GK10 and that's about it. I don't have serious listening experience with any other IEMs, so keep that in mind.

My music library is full of different genres – Prog Rock, Metal, Hip Hop, EDM, different OSTs… These played basically anything I threw at them like champs. OOTB, some of the tracks showed a bit of harshness in the highs/upper mids, but I believe the burn in did it’s thing and the sound became nicely rounded. These are now giving me detailed, holographic sound with just the right amount of quality bass. Mids are almost to die for, beautiful and engaging as they should be. Where these may be lacking a bit is in separation on very busy tracks – think of Devin Townsend and his walls of sound, or some extreme Metal. But this music is hard to replay for any headphones, so I guess I’m nitpicking here. What I know is, that if the track has been engineered and mastered well, it’s an absolute pleasure on these.

As a source I’m using either HiBy R5 (OG version) or Cambridge Audio DacMagic XS. Sounds great on both, but R5 can give these some serious juice from the balanced output to make them sing to the best of their potential. I mean you can really crank it up and these babies will keep their composure across the entire range.

What is also worth mentioning is the size of the shell. These are tiny compared to some of the other tribrids, which I find absolutely brilliant since I have smaller ears.

I know that it’s a huge jump in quality coming from BL03 for example, but I’m really rediscovering my entire music library which is extremely exciting! When I regularly get shivers down my spine during listening sessions, I know I have something special. And yes, I’m either bobbing my head or foot-tapping constantly 😊

Think I’d give these something like 4,75/5 ⭐
