I listen to alot of electro yeah, less so metal, but some very intense jazz rock, math rock or experimental or post rock etc...prefer classical guitar to electric one but electric guitar is very hard to sound properly IMO I have friends that listen (and make) to metal, drum is so freakin fast that I feel it need TOTL iem to achieve right amount of weight and all details.
For earbuds, I really don't think smartphone can be a good source, and for IEM its risky, especially bassy one cause sometime bass is already tweaked to please POP enthusiast and such...rarely DAC section isn't uncolored with some implementation trick to make it exciting, I guess this trick can be good for some but I'm post trauma about my Ipod touch that sound ultra bassy even ''without'' eq preset. For dac, there very ultra cheap one nowadays for phone on aliexpress...just receive one at 7$ lol...not sure its good cause if YEAH sound is clearer it did not give lot of power so for iem its a good choice but not for earbuds. In another hand, the ES9018 DAC Audio one at 25$ is really good, but I can just use it on my laptop cause my LG G6 do not want to amke it work! So frustrating, hope it will work for my mother on its Samsung S8 (its a gift for her).
Really man, give it a try, I think you will be amaze about details retreival and it should work on one of your numerous phone hehe
Anyway, im not a phone guy....and my favorite DAP is a Old ibasso DX90 that survive to anything even falling on ice and loosing its battery in the snow. Make 4 years now I think....best audio investment of my life.
Meizu seems to have neutral sound. Now I'm really demanding on the quality of signature on Jack. And I compare with a lot of smartphone.
A s845 dac without any eq is bassy and boring in treble. Bad sound
For example a OP6 is very ugly... The EQ is.... So artificial my god....
Meizu is a reference in mobile audio phone, like vivo and better than lg.
