An exceptionally smooth, even-toned timbral presentation throughout the entire frequency spectrum with a tidy, pinpoint bass response is the signature sound of the Oppo PM 3. The proprietary ultra low-distortion Oppo planar drivers present a spry dynamic quickness with great clarity in the mids & upper highs that's hard for traditional dynamic-driver sealed headphones to match at this relatively affordable price.
The PM3 bass response stays laid-back and its sense of relaxed, easy pacing extends to the silky treble ranges which ring clear and mellow without any sharp timbral edges. We think the rounded acoustic warmth of the Oppo PM-3 remains one of its most engaging audio strengths.
Tipping the scales at a skinny 10 oz., the Oppo PM-3 is certainly among the world's lightest closed-back planar magnetic headphones. The elegant styling and exquisite high-end workmanship give the headphones a lovely cosmetic appeal, and the very secure fit ergonomics allow comfortable listening on the move.
The headband clamping force on the ears can perhaps feel a bit squeeze-y after long all-day listening sessions but the tight seal of the earpads contributes to the strong isolation factor from the loud ambient world. So the PM-3 blocks out quite a bit of environmental noise while also effectively preventing sound 'leakage' from the headphones. This makes the Oppo PM-3 a superb choice for commuting, traveling, office cubicle jams or late-night listening.
