COMPLETELY BLOWN AWAY- by the dirt cheap bl03s, had them for months, was using some old biflange eartips( possibly came with some Sennheiser iem) and they sound good..but by no means great.
Couple of days back found my old box of iem eartips ( there are at least 80-90 pairs all mixed up) and changed the tips with large olive shaped tips ( possibly came with those rubbish overpriced Shure 535s)
That completely changed the sound!! Those 30 bucks iem sound absolutely ****ing perfect. Of course I haven't heard many uber high-end TOTL iems but definitely wasted lot of money on big brands like Shure, Sennheiser, Etymotic, relatively expensive Chinese manufacturers like Dunu,FiiO, One more and very few cheap chi-fi like KZ.
The few KZs I have/ had, sound similar and I possibly will be able to pick up the badly tuned multiple BA IEMs ( specially the very poor and overpriced Fiio FA and hybrid FH series, all KZs) on blind testing.
But the bl03s are different, with a proper seal, they absolutely crush each and every iem I have ( excluding the custom pairs, but those are for stage use, they are not pleasant sounding at home or on the go, and a complete rip off) which includes ie80/ 800, Shure 535, the etys ( er4 possibly)
The detail retrieval ( etys) soundstage (ie 80), bass ( ie 800) mid (535) high ( etys) etc. may not be top notch individually, but the coherence and that vague thing called timbre by audiophiles are absolutely crazy.
For me, coherence is the most important thing in iem universe ( I'm not too familiar with IEMs compared to full sized headphones) and this little cheap, shiny unknown single dynamic driver unit is by far my best purchase in audio equipment.
Since it's cheap ( must be around 2-2.5k in India) will humbly request audio enthusiastics here to try it out.
If you love the sound of M50X, 1000XM3, these little things will change your perception of portable audio.
For the first time the audiophile hype train crossed all my expectations.
I'm pretty sure it was created accidentally, hope other manufacturers ( specially FiiO) take this gem as their standard and start improving it even further ( taking down few dB from midbass, find a way to widen the soundstage and make more ergonomic models) and Blon increases size of the nozzle by few millimetres.
