Lightweight Open-Ear Design

Ugreen HiTune S3 open-ear earbuds weigh 5.3 grams each and use a C-shape clip that secures to the ear edge. The fit leaves the ear canal free so cyclists, runners and commuters stay aware of traffic and conversation. They suit anyone who finds in-ear tips uncomfortable during long sessions.

Bluetooth 5.4 Range And Latency

Bluetooth 5.4 provides a stable link up to 10 meters with 0.08 second latency in Game Mode. The standard does not support multipoint pairing or high-bitrate codecs such as LDAC. Buyers who need simultaneous laptop and phone connection or lossless streaming should consider other models.

IPX5 Build And Touch Controls

An IPX5 rating protects the housings against sweat and rain during workouts. Touch panels on each bud handle playback, calls and mode switching without a companion app. The case charges via USB-C and delivers 7.5 hours per bud with 30 hours total; a 15-minute top-up adds 120 minutes.
