AceFast T9 Crystal Air true wireless earbuds deliver rich, detailed audio with 9 mm composite drivers, dual speakers, and support for SBC/AAC decoding over a 20 Hz–20 kHz range. They produce clear treble, bright mids, and deep bass, while sound isolation and SVE AI call noise reduction keep your music and conversations focused and immersive.
Bluetooth 5.3 with the Bestechnic BES2600IHC chip provides a stable, low-latency connection to smartphones, tablets, and laptops, and touch controls let you manage tracks, volume, calls, and Siri voice commands directly from the earbuds. The low-profile in-ear design, four sizes of silicone eartips (SS, S, M, L), and IPX4 splash resistance make them comfortable and secure for everyday use.
A compact 480 mAh LED digital display charging case with gradient coloring shows real-time battery status and charges via USB-C. Each 40 mAh earbud delivers up to 6.5 hours of music playback (4 hours of calls), with up to 30 hours total from the case, and fast charging gives around 2 hours of listening from just 10 minutes in the case. A silicone protective case, lanyard pendant, and modern true wireless connectivity complete the package.
