im currently using blon bl03 version 1 , which is good for valorant but not perfect one. actually what i come to know that every person has its own sound taste regarding his capability of listening , some love bass some hate , some love treble some hates. so i concluded that before buying a new iems just give a 30% conclusion on reviews, 30% on graphs and rest is your risk of buying new iems. but look at graph first and analyze that are you a bass guy or treble guy or if you buying for gaming then you need good treble and good mids and a slightly bass and a best proper sound staging helps directional sounds so keep these things in your mind and you are good to go. and 1 thing more i will definetly give a try to em6l than supermix 4 heard that supermix 4 sound staging is somehow become harsh when sudden frags and guns fires sounds collectively coming from same direction on in team fight supermix 4 become harsh which effect sound staging.

Blon BL-03 was my first real introduction and the only thing I regret is letting the hobbyist and collector mindset consume me. I now have too many IEMs and too little money!

Blon BL03ii. Cut a bit of the nozzle from any other eartips that you do not use, put it down over Bl03ii's nozzle and then put the eartips that you want to use with the iems.

Admittedly from Chifi - got into them during E1001, Whizzer, KZ ZS days and started going down the rabbit hole of "oh this sounds rich, that sounds smooth this neutral that soundstage". 15-20 pairs in, I just got tired of 'chasing' the best sound for the best price because there is always something new and new =/= better. I also worked through dozens of DAC dongles and finally just went TWS for practicality. In hindsight, nothing got me feeling as pleased as my bl03 with foam tips. They sure aren't the the universal best, but to me the sound was so smooth and relaxing. Occassionally I take them out and listen to them at home. But when I'm out and about, I just use my Nothing Ears. But secretly waiting for them to die on me so I can justify a pair of Technics. By the way it's like this with a lot of different hobbies. It's a tiresome cycle but the joys must be worth it for people to do it over n over.

Because you want good passive isolation, you are going to want to avoid the Gate, the Bunny, the LAN, and the Wan'er. While i am a BIG fan of the Bunny, they might as well be open backed. Same with the Gate. The Wan'er also has a LOT of sound bleed. The Vivace is a little better, followed by the Cadenza, the Zero2 and the Chu 2. Overall, isolation wise, the Chu2 is the best on that list. But i would caution that, if you are going to be in the worship band, sweat is an issue. And 1: Metal Shells and Sweat usually means corrosion. 2: The Cadenza nozzles are WELL known for their corrosion. So...sadly, dont do that. I would look at the Cadenza, or the Zero 1, not the 2. As they have a flatter bass profile, and a little more upper mids presence. Which will fit into the vocal range a little better for actual live monitoring. Some other options i would look at are the TRN MT5, the Simgot EW100p, the BLON BL-03 II, Kinera Celest Wyvern Black, the Remix version if you want more vocal forwardness and less bass, and most importantly, tips tips tips. Get yourself some memory foam tips, and use them, this will GREATLY improve isolation and fit while playing. Or some foam filled silicone tips. To help reject outside sound.

What? The BL-03 is smaller than the CHU. Its so small, I've used it for side sleeping, and I don't have big ears.
