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
