Design and Build Quality
Charging Case
Overall, the Edifier wireless in-ear earphones have a simple design inspired by the AirPods Pro. As for the charging case, it features a familiar rounded rectangular design with corners, small and lightweight, weighing no more than 50g, made of glossy black or white plastic, with the Edifier logo printed on the back.
In the middle of the front, there is a long groove for opening the case, surrounded by magnets to facilitate easy opening and closing. Inside the charging case, there is a place for the earphones with automatic charging feature. And underneath, there is a slot with LED indicators, indicating the battery status. To operate, there is a multi-function physical button on the back.
Unfortunately, the bottom part of the charging case is circular, so you won't be able to stand it up. The presence of the Type-C charging port is crucial, although it would be better if it were placed elsewhere, especially on wireless charging cases.
Headphones
The Edifier TWS330NB wireless headphones are sleek with a small design, short body, glossy black color, and most importantly, a lightweight form of only about 4g for comfort on the ears and stability while moving. This is aided by soft silicone ear tips with a round hole to reduce pressure inside the ear, able to balance air pressure indoors and outdoors while providing ventilation.
Additionally, the 'L' and 'R' logos are printed on the earbud ends to distinguish left and right ears. Nearby are the magnetic charging contacts and micro-receiving slot to capture clear sound in calls with the support of external noise reduction slots on the headphones, working in tandem with the microphone to accurately distinguish between human voices and noise.
Control Mechanism
And for control, their touch-sensitive control panel is placed at the top of the headphone stem with an LED indicator light, achieving precise control with highly sensitive touch sensitivity.
- Double tap on the right earbud: Answer/End Call Pause/Play
- Double tap on L to switch between ANC on, Transparency mode, and ANC off
- Triple tap on R to skip to the next track
