Notes: The OPPO PM-3 headphones are known as the “Portable Planar Magnetic’s” since they can be powered from a phone’s headphone jack.

Feedback says they do still benefit from amping.

Some have experienced brand-new pairs having slight distortion in the sound especially when bass hits, this has been reported to go away after extended use.
