We've seen several ThieAudio products before, and every single one has impressed, going from the $99 Legacy 2 to the $729 Monarch. ThieAudio is an in-house brand for Linsoul, a major audio distributor based out of China. HarmonicDyne is very similar in that Linsoul is a primary distributor and works directly to influence the brand's products, and the way I saw the two was that ThieAudio was more on the IEM side with HarmonicDyne more focused on headphones, including the Zeus that has been getting rave reviews and we will eventually cover. Things get blurred when taking a closer look and see there was a ThieAudio set of headphones, and we now have a HarmonicDyne-branded IEM! Thanks to Linsoul for arranging a review sample to TechPowerUp.

I asked Linsoul how exactly the two brands operate next to each other, with blurred lines getting more so with the two now sharing some common ground. This first-ever set of IEMs from HarmonicDyne, the P.D.1, is based on public response and requests. For now, ThieAudio is still considered a more mature brand in terms of supporting more products, and with better tuning. This already rings some alarm bells, but knowing that the "P" in P.D.1 stands for planar magnetic drivers leaves me intrigued. Let's see how the HarmonicDyne P.D.1 fares in our testing as we begin this review with a look at the product specifications below.
