LISTENING EQUIPMENT USED IMPARTED HUGE INFLUENCE TO SOUND IMPRESSIONS & RATING


💚PROS

  • Clear crisp neutral flat timbre with uncolored tonality
  • Well controlled dynamics, full bodied with smooth airy presentation
  • Great well nuanced Micro and Macro details
  • Balanced Mids with smooth textures and definition, natural toned Male/Female vocals
  • Smooth Treble with crisp decays, great extensions
  • Smooth Mid-Bass, tight, fast with crisp decays
  • Sub-Bass exhibited audible seismic response with mild decays.
  • Crisp and vivid guitars, piano, percussions (chimes, bells) and drums and taps
  • Decently wide soundstage width with good depth and placement
  • Great holographic spatial imaging with proper placement/layers
  • Amazing speed and dexterity on complex passages and transients
  • Super clean background, zero floor noises
  • Clean layers and well-defined separation lines
  • Drives Magnetic Planars and BA at 75/100 volume for normal listening level.
  • Excellent synergy with DD and BA (below 50Ω)
  • Great for marathon listening sessions, as it would not induce fatigue.

💔CONS

  • Driving power is just about enough for demanding IEMs/Headphones.
  • Spatial imaging not razor sharp enough compared to the top contenders.
  • Being analogue sounding, transparency sacrificed a tiny bit.
  • Less likely to synergize well with magnetic planars.
  • No volume adjuster
  • Cable a bit too long (the longest unit so far)

VERDICT

JSAUX Type-C. This thing sounds great for the money. It offers balanced neutral timbre with solid dynamics and healthy amount of airy presentation with refined smoothness. A bit less edgy because it is tilted towards organic and analogue sound, in fact I am liking it a lot because it sounded this way. This JSAUX pairs perfectly with an already technically competent IEMs/Headphones and will NOT sound the best with an already warm or slow types. If you have an Etymotic ER series, Etymotic EVO, Shure KSE1500, Heart Mirror, KBEAR NEON, TRN-MT1, QKZ VK4, BLON BL-Mini or anything within that nature, this JSAUX will sound great and satisfying. However, may not sound the best with Magnetic Planars or DT990 – and this can totally be forgiven considering that no sane person should expect a $6 USB DAC/Amp to drive those beasts any which way you look at it. Nonetheless, my Tin HiFi P1 and Monolith M565c still sounded decent enough for casual entertainment at volume 75/100. I am giving this one a very high rating over 90 purely because it synergizes insanely great with my ER4SR and ER2XR…..and not forgetting it cost just $6, cheaper than a pair of our IEM tips.

PS: Also available in Lightning version for iOS

⭐⭐⭐⭐ ($6.00)

Best Pairing: Technically competent IEMs between 8 to 75Ω
