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: IEMs and easy-to-drive headphones, wired or wireless, with serious EQ control.

A pocket DAC/amp with a balanced output, LDAC, and a 20-band parametric EQ that applies to every source on the phone.

What we like

+ 20-band parametric EQ runs on the device, so it corrects every app on the phone, not just the music player
+ EQ profiles are stored on the 5K itself and travel with it between phone and laptop
+ Balanced 2.5mm output rated to 4VRMS, which is unusual in something this size
+ Works wired over USB and wireless over LDAC and aptX Adaptive, so it covers both use cases

Watch outs

- Almost no physical controls, so everything runs through a dense app with a real learning curve
- Battery falls to around six hours on LDAC, which does not cover a full day of use
- Not enough authority for 250 to 300 ohm headphones, so it is an IEM device in practice
- The clip and body are small enough to lose in a bag, and replacements are not commodity items
