About Me: Andy.EF

This rabbit hole of portable audio obsession of mine started back in 2006. Since then, I have been active in the scene, trying out this and that. What remained consistent until today, I am firmly rooted to portability and will use my portable rig almost all the time even at home. After 2010 things slowed down and I wasn’t as active until recently when Covid brought humanity to a standstill. So began the lifestyle of confinement that we all endured and for me it gave me the excuse I needed to delve back again into this addictive rabbit hole. So here I am, not being able to do vacations and stuffs like that. To fill the void, I find myself gradually and steadily piling up interesting portable audio gears in the pursuit of that Endgame sound. I am based in Malaysia, and this is my impressions on some of the gears that I have acquired recently.



  • These are my own items purchased with my own money. No sponsorship, However I would like to clarify that HifiGo has been kind to ease my burden by offering good discounts on my subsequent purchases (because I can’t stop buying) and I will continue to do this as an independent entity. Free to write my impressions and thoughts from the perspective as a user. I do this because it is fun, and I love trying out gadgets. I have also agreed to keep a copy of this #donglemadness on HifiGo site as a mean to help fellow audio enthusiasts in getting better perspective of the dongles that caught their attention.
  • Dongles usage on my tests are for IEMs and Headphones NOT exceeding 250 Ohm, minimum sensitivity of 96db.
  • The results and rating done are heavily influenced by the nature of the IEMs/Headphones used. A dongle will score high if they exhibit great technical ability while remaining smooth sounding at the same time - the most technically competent ones does not necessarily mean they will be superior in my POV. I will rate a dongle more points if they exhibit great flexibility with different type of IEMs/Headphones – meaning they are easier to establish synergy.
  • My preferred sound and timbre signature classified as Neutral, Natural Flat - Analogue and Organic tonality.
  • I describe what I hear, no more no less. No techie measurements involved. There will be no FR measurements or anything like that as I have no access to such tool, nor do I know how to operate them even if I have one in front of me.
  • Please excuse my haphazard format, I am not a professional reviewer, and I wrote things as I heard them. Also, I will use non-conventional analogies to describe what I hear, sometimes I describe them as if I am savoring some food
  • Agree to disagree, what is beautiful to my senses could be utter shit to you.
  • I NEVER use software EQ. So don’t expect my writings to include FR range because I am not proficient in pinpointing those numbers.
  • My tests do not include anything above 44.1/16bit. I am an Oldschool FLAC Junkie.
  • I don’t use UAPP to bypass Android SRC since I have no need for Bit Perfect beyond Android stock 48Khz limit.
  • I am 46, so my senses are a bit denser than it was 10 years ago. My tolerance level to sibilance is as trained as it is forgiving. Younger folks may be less similar.
