Masterpiece of a DAP by iBasso
"I have owned an iBasso Max starting with the 300 and most recently the 320 and all have been amazing, but the one thing that always seemed to not change was battery life depending on the music file type could have been 6 hrs to a little over 8 hrs at best. Surprisingly though the new 340 MAX is pushing beyond 15 hrs . Pleasant surprise All my iems sound fantastic and am driving my Hifiman HE1000 and Dan Clark Noire X quite well. Not cheap by any measure but you know what you paid for when you get it. Plus the older units in good condition still hold good value."
