It seems that Harmonicdyne's first IEMs are releasing soon and are now on preorder at linsoul, shenzhenaudio, and hifigo. Not sure if anyone had a chance to listen to these or if you've seen any pre-release reviews of these?

From the description:

How We Have Developed P.D.1​

HarmonicDyne quickly took a place in HiFi headphone industry with its professional high-standard headphones, like Zeus and Helios. Both headphones have received many positive feedbacks and advice which greatly encouraged the team to go further. Thus HarmonicDyne is stepping into the IEM industry with their latest pair, the HarmonicDyne P.D.1 which features a hybrid driver of planar and dynamic driver with aluminum alloy shell. Derived from the two letters from planar and dynamic driver, P.D.1 comes into being. The name speaks for itself as a hybrid driver IEM and its unique driver configuration will deliver you a natural sound.

10mm Planar Driver+10mm Dynamic Driver​

HarmonicDyne has equipped the P.D.1 with the latest planar driver with high magnetic flux paired to a customized dynamic driver unit (CNT at the edges and DLC Dome), bringing the best of both worlds together to create a unique musical experience. These two drivers greatly complement each other to present you a uncomparable sound.

Double Cables For Different Needs​

You get P.D.1, you get a “Double Dealing” . No matter you are into vocals or classic, 3.5mm stereo or 4.4mm balanced, we covered it all for you. This product comes with a copper silver hybrid balanced 4.4mm cable, and a silver-plated OFC copper 3.5mm cable. These two types of cable will fit for most devices and meet most needs for sound or instrument.

CNC Aviation Grade Aluminum Alloy Shell​

Embedded in modern industrial design, P.D.1 adopts aviation grade aluminum alloy for the shell to present a high-class and exquisite look. With 5-axis CNC machining process, manual grinding and polishing, the shell feels nicely textured with natural gloss.

Natural Tuning​

We wanted to present a sound that was both accurate, and musical yet natural, HarmonicDyne has uniquely tuned the P.D.1 to provide a soothing experience with good sparkle and energy. The pair produces a natural bass response with lovely full-bodied vocals and smooth well-extended treble frequency response.

I did find this review. Seems like it's pretty bad.

What a disappointment these were. Luxurious unboxing, really nice cables and accessories, mediocre but flashy case, and that medicre but flashy part applies also to the IEMs in general. A poor choice of hardware and definite let down by tuning, so much so that it's hurt the HarmonicDyne brand in my opinion. I do want to see if Linsoul tries again with IEMs under this brand but with better tuning, and in the meantime maybe offer those cables under the HarmonicDyne brand to get more interest outside of the Zeus headphones.
