Yes, but you should be able to manually select the gain modes. Just because a headphone is low impedance does not mean it is easy to drive
I have found only my really good pair of headphones make much of a difference. I would have liked to see it work with the phone's speaker, which by the way should be a lot better at this price point.
Sounds great with studio headphones or monitor speakers. Sounds better than my laptop. I have the ATH-M40x. Very glad to have it, music sounds amazing, I hope they don't take it off on the V30.
This phone sounds great on LG Tone Active plus Bluetooth headphones. I'm very impressed!
Supposedly there is a fix for better speaker sound on the V20. You have to remove the speaker grill though. I haven't tried it (have to build the courage, lol) yet. Only draw back is that by removing the grill more dirt and dust might enter the phone. Here is the link:
