HarmonicDyne PD1 – Overview and Unboxing

The HarmonicDyne PD1 is out to make an impression. That begins proper from the unboxing expertise with one of the vital distinctive packing containers I’ve seen for an audio product. The field is textured in a paper-like method and a small ornamental sleeve have to be eliminated to entry the bigger field. Excessive marks for outward presentation.

As soon as the field is opened, you’re offered with the IEMs and a journey case displayed on the left and a number of silicone ear suggestions and metallic possession card on the fitting. (As an apart, don’t thoughts the one black tip. That’s a stand-in as the opposite is in-use). Mine unit was serialized No. 134, so I’m testing a unit early within the manufacturing run. We’ll dig extra deeply into these equipment shortly.

Beneath the ear suggestions are two packing containers that every home a separate cable for these IEMs. That’s proper, whereas it’s widespread for IEMs to incorporate removable cables, the PD1s embody each a balanced and single-ended cable to ensure it might connect with your gear and actually be pushed to their restrict. These cables are an absolute excessive level to the bundle, every thick and rope-like with tightly-woven braids. Regardless of their girth, they don’t kink or coil simply, which makes them straightforward to put on and handle. Each additionally keep away from microphonics – the noise that transfers up the cable when coming in touch along with your shirt or jacket. There’s additionally a ¼-inch adapter for the single-ended cable.

Taken as an entire bundle, it’s a beneficiant bundle. The cables alone may simply run upwards of $75 bought outdoors of this bundle. The opposite objects are solely so-so. The case appears good however feels fairly skinny. The ear suggestions have been additionally problematic, the black suggestions too free to suit securely in each ears and the pink suggestions too agency/too massive to put on with out utterly sealing my left ear canal with out leaving my jaw barely slack. Everybody’s anatomy is totally different, so your mileage could fluctuate, however I’ve by no means been capable of not discover a match earlier than.

Shifting to the IEMs themselves, we now have aluminum shells with a fantastically reflective end. The faceplates protrude a contact, inflicting reflections to scatter in an interesting approach. The general design follows conventional Common IEM shaping with contours permitting the PD1s to nestle into the pure folds of the ear with out protruding an excessive amount of. There’s a triple-point vent on the again rear of every to alleviate stress and improve their consolation. The nozzles are additionally lengthy sufficient to suit securely in your ear canal — assuming you don’t have the identical situation I did with the inventory suggestions.

Inside these shells, the PD1s function a hybrid driver array. Every shell features a 10mm planar dynamic driver for the mids and highs. Bass duties are coated by a 10mm dynamic driver. Planar-driven IEMs are nonetheless considerably unusual within the IEM world however are now not remarkable. The thought is an interesting one: all the element and readability of a planar with out the cumbersome over-ear bundle you’d sometimes be pressured to. The dynamic driver has additionally been enhanced with a diamond-like carbon dome and carbon nano-tube edges. 

The draw back to together with planars in an IEM is that they’re notoriously energy hungry. With an impedance of 16 ohms, you may suppose that PD1s are straightforward to drive however don’t be hasty. These IEMs will run and sound respectable with a $20 dongle DAC, however relying on what you’re driving them from they simply gained’t sound their finest and should expertise uncommon audio artifacts (like distortion across the fringes of sure vocals). You must give them extra energy. I like to recommend selecting up an reasonably priced moveable amp just like the Fiio A1 or Topping NX1 to be used on the go. At residence, I ran them from my XDUUO XD-05 Plus however was capable of push them simply tremendous with each my Presonus audio interface and GoXLR, so don’t break the financial institution on amplification. Nonetheless, amp these earphones.

HarmonicDyne PD1 – Match and Consolation 

By no means earlier than have I felt a lot just like the Princess and the Pea. Utilizing the included suggestions, I wasn’t capable of finding a dependable match regardless of which mixture I attempted of every colour. The black suggestions are softer and labored higher for my left ear, however have been too small for my proper. The pink suggestions are firmer and labored nice for my proper ear, however even utilizing the smallest measurement, have been too massive for my left. Inserting it sufficient to really feel safe and ship the correct quantity of bass, closing my jaw sealed off my ear canal sufficient to utterly kill the sound. Provided that ear suggestions can affect sound, mixing and matching wasn’t possibility both. Very, very bizarre and a primary for me throughout dozens of IEM reviews.

Fortunately, I used to be capable of pull one other pair from a set of Fiio headphones I had close by and resolve the issue. The ironic factor is that this downside may have been prevented totally if HarmonicDyne had included a set of froth ear suggestions, however regardless of the excessive worth, it was silicone solely.

With the ear tip situation sorted, consolation is definitely fairly good. Full-aluminum IEMs will be heavy and slip out over time, however that wasn’t the case with these. The buds are medium-sized and have been capable of be supported simply by my outer ear and stayed in place nicely. Even after a number of hours, I didn’t expertise any soreness or irritation. 

HarmonicDyne PD1 – Listening Impressions

HarmonicDyne has an fascinating description for these headphones. They emphasize the “pure” and “soothing” sound signature with “good sparkle and vitality.” These two descriptions nearly appear at odds, however after spending a pair weeks with these headphones, there actually is a dynamic high quality to those earphones that permits them to work for relaxed, acoustic music all the way in which to crashing heavy metallic with a satisfying general sound.

So let’s break that down. These headphones have a U-shaped sound signature. The bass is deep and wealthy, so when kick drums and low bass strains kick in, you possibly can actually really feel their affect and presence. The planar driver does job of pulling out mid- and high-frequency element, which is the place the flicker is available in. Listening to acoustic or atmospheric jazz, like Arve Henriksen’s Saraswati, I used to be repeatedly stunned by how nicely articulated tiny particulars within the combine have been. Chimes, quiet cymbals or excessive hats, didn’t break up prematurely. Within the mids, vocals are certainly intimate and pure sounding. Devices on this vary, like trumpets, impressed me with how detailed they have been. Clearly, the tuning and driver mixture are nicely achieved and finely tuned.

One other factor value mentioning is that the PD1s have one of many greater soundstages I’ve heard from a closed-back IEM. I’m unsure how they do it, however I discovered myself double-checking my cellphone to ensure Dolby Atmos wasn’t enabled all through the review course of. These IEMs gained’t substitute set of open-back cans, however the sense of area and air they ship is spectacular.

However with that, we now have to return to energy. Regardless of their 16 ohm impedance, these earphones simply don’t compete with out sufficient juice behind them. Very similar to the Tin HiFi P1s, I think we’ll see opinion cut up on these headphones amongst people who find themselves driving them with some sort of amp and people plugging straight right into a cellphone or headphone jack dongle. Likewise, they simply want quantity.

Earlier than scripting this review, I went backwards and forwards between a primary dongle DAC and my desktop amp listening to Spotify on its highest high quality setting. There may be a right away and noticeable bump intimately and area shifting from a low-powered dongle to a correct amplifier. Worse, listening via that dongle DAC generally resulted in audible distortion on the fringes of male vocals. This didn’t happen on the very same tracks with a correct amp. Give. Them. Energy.

Last Ideas

The HarmonicDyne PD1s are an fascinating earphone. Not solely are they a departure from what the model has achieved earlier than, however the mix of planar and dynamic drivers isn’t precisely widespread within the earphone area. I actually loved their sound signature and the added crispness the planar delivers within the mids and highs. The bass can be darned good and actually fills out the music with actual weight.

The sticking level right here is worth. At $379, they’re an costly headphone that basically calls for outdoors gear, be that ear suggestions or an amplifier. I actually take pleasure in these earphones, however on the present pricing, they’ve steep competitors that additionally delivers excellent sound high quality with out the necessity for an amplifier to actually sound their finest. The PD1s are doing one thing distinctive, nonetheless. The planar dynamic mix works nicely and, frankly, has a better value to implement. The 2 inclusion of not one however two wonderful cables helps mitigate the excessive worth, too. 

The purpose right here is that it is a reserved advice. These earphones have rather a lot going for them, however they’re value actually contemplating earlier than pulling the set off at this worth.

The product described on this article was offered by the producer for analysis functions.
