DQ6S

The boycott is irrational. I bought the kz dq6s and it sounds great.

I have the KZ caster Pro, KZ x Angel ears, KZ × HBB DQ6S, TRN Conch and the TRN V10 Pro ♥

I got a set of each and I could still not fit them, sadly and they were not the smallest I had found either. I got a random cheapo pair off AliExpress and they're about half a millimetre smaller, but still not small enough :(

The kz dq6s is very very loud and I think has the pin you are looking for. The pr2 or prx are the worst option for the Bluetooth ear hooks because they need more power than most standard headphone jacks put out to really open up and sound the best they can. The Bluetooth ear hooks in my experience with my azo9 that I have are a little weaker than most things I have with a normal headphone jack.

Not all of them. I also have KZ Gale and DQ6. Both of their nozzles are smaller (about 5mm wide) while Castor Pro's is 0.5mm wider. It doesn't seem much, but the difference is huge.

I got DQ6 to replace castor pro since it has smaller nozzles. When I looked at graphs, they have similar tuning especially in when it comes to bass.

I tried KZ AS10 and DQ6, Blon BL-Mini and A8 Prometheus, Moondrop Kato, B2, B2 Dusk and S8, Softears Studio 4 and TinHiFi T2 Plus. Tin were trash. KZ AS10 was okayish but not really. DQ6 super comfortable, lightweight decent SQ for the price and comfort but nothing crazy. From Kato to B2/Dusk there's a significant step up in SQ. From B2/Dusk to S8 there's an improvement but it's not something crazy. The Blons sound OK, BL-Mini is quite decent in terms of price to performance, A8 are overpriced in terms of SQ but they look amazing. Both are lower in SQ than the Kato. Studio 4 sounds amazing to me, it's a more mid centric sound signature. The S8 has a more spacious sound and has more perceived space between instruments but the S4 is just godly in terms of it's timbre, everything's sounds just right, notes are weighty of I had to describe it somehow, and vocals are on another level altogether. I'll soon hear the RSV MKI. Thus far from this lineup I'd say diminishing returns start at the Blessings, now... The S4 I think is a justifiable step up, the S8 if you have the disposable income yeah, otherwise you spend more and you get more but not that much more. The S4 is cheaper than the S8 and I'd surely recommend the former. I guess it boils down to how much you are willing to spend. There is an improvement in SQ but it's definitely not a linear function, it's evidently logarithmic, just like horsepower in cars. I'm sure though there's plenty of snake oil sets out there. I'm sure if you bought the Hexa or the Nova and compare them with the Kato the latter would feel like a scam. That being said SQ is not the only factor, I have the Blons almost exclusively for how they look. I've met people that were like meh they all sound the same. I think I trust myself as I found the S8 underwhelming compared to the cheaper S4, and I really wanted to like the S8 as they look gorgeous, but I truly believe the S4 are the better pair. And bro, damn... those TinHiFi T2 Plus, 60 bucks? I wouldn't take them for free... Everything sounds like an out of tune banjo with only two strings left played by a crackhead that lost half his fingers.
