The PM-1 Planar headphone by Oppo

Final Thoughts

In the end and at $1099, Oppo’s PM-1 is a fantastic first step for this company into the headphone world. Oppo set out to achieve something specifically setup for a consumer grade-hifi sound signature. They nailed it. There is a new Titan on the block and the Old Gods need to pay heed and tribute. In terms of sonic clarity to price ratio, the PM-1 is very good. Smart and practical design fused with very nice sonic qualities will make for one of the best entry level summit headphones on the market. Musicality is through the roof on this headphone. Minor fixes would make this headphone a solid 10/10, but I am giving it a 9/10 instead. In my humbled opinion, the PM-1 offers one of the best values to performance ratios in the headphone world. Great job, Oppo!

I’d like to thank Oppo for allowing me access to this headphone, for being the most responsive and support concious company I’ve ever spoken to and lastly for producing one of the better headphones to come along in a while. I’d also like to thank Artemis Cables for providing some excellent cables for this review.
