Each day that passes i like my tehnz p4 pro more, and BGVP DMG less.
I actually did a A/B on dmg and kz zst and found them uncomfortably similar sounding :/
Of couse, the bass on Zst are looser, mids on DMG'S are thicker, the imaging is more precise and the sounstage gets more depth, but anyway. Too pricey v shaped signature for me. The mid bass is killing this earphone.
I recommend only if you want a V shaped iem, and in that case, the hifiboy v3 aparently doesn't have the annoying mid bass, and also TFZ king pro should sound more visceral according to b9s review.
I am trying to get rid of mine to get a moondrop kanas/kanas pro
Single dynamic coherence
I also think the tehnz p4 pro benefit from an AMP, not any, but a desktop AMP designed for power hungry cans. Plugging them on my topping a30 in the 30ohm output impedance makes them sound bigger, with a much better Bass, more articulate and less congested on the lower end. I think the power can lower the distortion ? I would be pleased if anyone tries p4 pro on a high power output with high OI.
I really see a difference from my Samsung s8, and my topping is plugged on my crap notebook motherboard soundcard (it is really crap) myabe some of the bass thump comes from it, but definitely not the lower distortion that i percieve. If the bigger thump come from the output (i can check later if anyone want) that means that the bass gets more dynamics anyway, being able to receive eq better than on a weak source and sounding more resolving in stock.
I would also ask you guys to try this earphone on balanced if you don't have a high power desktop source, the difference should be also there, IF am not crazy.
These earphones growed on me. They are much more closesr from my he4xx than DMG's for example.
When my desktop dac arrives i will have the final answer.
