Qudelix-5K Bluetooth USB DAC AMP with LDAC

Qudelix-5K Bluetooth USB DAC AMP with LDAC, aptX Adaptive, aptX HD, AAC (Dual ES9219 3.5mm Unbalanced & 2.5mm Balanced Output)

A tiny DAC and amp that does almost everything. The Qudelix-5K pairs dual ES9219 chips with a deep app-driven equalizer in a clip-on body.

  • Dual ES9219 DAC with 2.5mm balanced (4V RMS) and 3.5mm (2V RMS)
  • Qualcomm QCC5124 supporting LDAC, aptX Adaptive, aptX HD, and AAC
  • 96kHz/24bit with an embedded double-precision equalizer
  • 500mA battery rated for 6 to 20 hours of streaming

Best for headphone fans who want both Bluetooth and USB in one.

Editor's note

The parametric EQ in the app is the real reason to buy this. It is a serious tuning tool hiding in a pocket-sized clip.

Why we picked it

Best for: The traveler or commuter who wants one tiny device to power IEMs wired or wireless with serious EQ control.

A pocket Swiss Army knife that does balanced output, killer EQ, and wireless all in one tiny clip.

What we like

  • + Balanced and single-ended output in a pocket-sized clip
  • + Pro-grade 20-band parametric EQ for every source
  • + Excellent codec support including LDAC and aptX Adaptive
  • + Works both wired (USB) and wireless
  • + Outstanding measured performance for the price

Watch outs

  • - The app has a real learning curve and few onboard controls
  • - Battery life tanks to about 6 hours on LDAC
  • - Not a desktop powerhouse for hungry 300 ohm headphones
