Design

The charging case of the earbuds is quite boxy and thick to be fitted in a pocket. The shiny Dark Grey does pick up some fingerprint and as well as swirl scratch marks easily.

There’s a 4 LED battery indicator on the front and a modern USB Type-C charging port on the back.

Opening the cover are the earbuds that hold securely with magnet. The fitting of the earbuds on the charging case and built is impressively good for their first TWS earbuds. The magnet is strong and the opening closing of the lids cover is solid.

The earbuds are considered lightweight as it’s made out of plastic. It has touch-capacitive on both earbuds. It comes with three different sizes of rubber ear tip for different ear canal shape.

Coming to touch-control, the KINGMAX JoyBuds 511 deserves praise. It has most of the controls that you need without taking out your smartphone. It does Play/Pause, Next/Previous, Answer/Reject calls, summon Voice Assistant and as well as the volume control.

Do take note, the volume adjustment is on the earbuds itself not your phone’s volume which still good to have rather than taking out the phone to change the volume levels manually.

Sound Quality

My expectation wasn’t that high as their are not an audiophile to begin with. However with the reliable audio chipset like the Qualcomm 3020 that features aptX and CVC 8.0, it’s consider good for everyday earbuds.

The 6mm audio driver is pretty decent with clear vocals, wide sound stage but slightly lack low frequency. This earbud brings great sound clarity but not for those who are looking for heavy bass.

The microphone quality were just average as it doesn’t have a stem design for better voice capturing. Still, the surrounding noise were manage to reduced by half thanks to the CVC 8.0.

Battery

Tech specs offered more than a day of use with the charging case. So far, I have used the earbuds for 4 days now with an average 2 hours of listening and the battery level still have half to go.
