A Casual's Review of the Binary Audio Dynaquattro IEMs

Disclaimer: Please note that I am not an audiophile, and this review does not delve into the technical aspects of the IEMs. My impressions are based on my personal preferences, and others may have different experiences with this product. I also have a very limited experience with audio products so please take this review with a grain of salt.

The Binary Audio Dynaquattro was lent to me as part of a review tour in the Philippines.

Pros

  • Build quality is superb
  • The cable is of good quality
  • Soundstage is considerably big, holographic imaging is AMAZING

  • Bass is perfect!

Cons

  • Bulky carrying case
  • Nozzles are on the larger side, can be uncomfortable for those with narrow ear canals.

General Product Details

Package Inclusions

  • IEM shells & cable
  • Carry case
  • 6 pairs of eartips in 2 separate baggies inside a small plastic case
The IEM Shells
  • The shell body is made of a translucent black plastic that when hit by light in a certain way will let you see a bit of the inner workings of the IEMS. The faceplate is made of CNC-ed aluminum, with some debossed gear designs, the inner recesses seem to be painted black.
  • The earpieces weigh ~6.6g. You will definitely feel the weight on your ears after some time.
The Cable
  • Nicely wound and braided, the cables feel premium! It doesn’t tangle at all, but it definitely has “memory” - meaning if you leave it coiled in a certain way for some time, it will want to keep that form.
  • The chin clinch and splitter are also made of metal and feel heavy.
  • The jack can be switched between the included 3.5mm and 4.4mm! There’s a peg-and-hole to guide the insertion of the jack to the cable so you won’t get the orientation wrong.
The Carrying Case
  • The carrying case is a clamshell made of thick abs plastic. The cover is transparent while the bottom is black. Inside is a
  • The carrying case is made of a matte plastic covering material that is prone to marks, so you have to be careful or you might scratch it easily.
  • It is also very bulky as a carrying case, weighing at 76g and has a dimensions of 8cm x 8cm x 3.5cm. I think it would be better called a storage case.
Subjective Review
General Usage Impressions
  • I originally used small sized wide bore Divinus Velvet eartips. They were definitely comfortable eartips, but I found the nozzles were just too wide and it felt like it was directly scratching my ear canal, so I switched to my small CP100. The fit and seal were better but I would have really liked the softness of the velvet eartips.
  • The shell’s shape is great! It gave me a great seal that my wife had to shout at me a few times before I could hear her. 😆
  • Due to the weight of the shells as well as the splitter and chin clinch, I am unable to wear these for an extended period of time. 😔
Sound Impressions
  • Right off the bat, I noticed just how VAST the soundstage is, it’s so good! It’s very immersive, and I enjoyed using these IEMs for watching movies as well as competitive gaming.
  • Speaking of competitive, I felt like I had wallhacks while using these! I caught enemies trying to sneak behind me in multiple games of Overwatch
  • I love how balanced the sound profile of these IEMs are, they don’t fatigue me at all.
  • Listening to music has also been quite enjoyable!

Final Thoughts
The Dynaquattro is now one of my favorite IEMs! The sound, comfort, and build quality is perfect! If only it were a tad bit lighter, I would say these would be the most perfect IEMs for me! If I owned these, I would look into aftermarket cables to get rid of that weight.

The price isn’t for everybody, that’s for sure. But if you have a 250 USD budget and are looking for a premium-feeling and sounding IEM, these might be just for you!
