Biyoso Bluetooth 5.4 True Wireless Earbuds

The Biyoso 5.4 Earbuds are true wireless, semi-in-ear stereo earphones with Bluetooth 5.4, touch controls, IPX5 protection and a USB-C charging case for up to 20 hours total playtime.

Designed for everyday listening, commuting and hands-free calls, these compact earbuds pair automatically, offer stable connection thanks to the TWS Bluetooth 5.4 chipset, and deliver clear stereo sound in a lightweight semi-in-ear fit. The included USB-C charging case replenishes the earbuds several times, and intuitive touch gestures control music and calls without reaching for your phone.

How reliable is the wireless connection and audio quality?

The Biyoso 5.4 uses a TWS Bluetooth 5.4 chip for faster transmission, lower latency and fewer dropouts than older Bluetooth versions. You’ll get consistent left/right stereo separation and clear voice pickup for calls.

• Dual-channel TWS 5.4 chipset for stable pairing and reduced interference
• HiFi stereo tuning for balanced mids and highs with defined vocals
• Built-in microphone for hands-free calling and clearer voice quality

How long will the battery last during everyday use?

Each earbud provides about 4.5 hours of music playback at typical listening levels, and the compact charging case adds up to three full recharges—around 20 hours total. Fast top-ups are convenient thanks to USB-C charging, and the case fully recharges in roughly 1.2 hours.

• Earbud playtime: ~4.5 hours (80% volume)
• Call time: ~3 hours (80% volume)
• Charging case capacity: up to three recharges for ~20 hours combined use
• Standby time: approximately 60 hours

Are these earbuds comfortable and rugged enough for daily life?

The semi-in-ear design keeps the buds light and non-intrusive while delivering high-definition sound without deep in-ear tips. IPX5 splash and sweat resistance protects both the earbuds and the charging case from moisture during workouts and light rain.

• Semi-in-ear shape for a secure, natural fit without silicone tips
• IPX5 rating: resistant to sweat and light water exposure
• Durable charging case provides repeated top-ups and on-the-go protection

How do the controls and pairing work in day-to-day use?

Touch-sensitive stems let you manage playback, calls and volume with gestures—no buttons required. The earbuds auto-pair on first use and reconnect automatically to the last device, simplifying transitions between phone, tablet or laptop.

• Tap to play/pause, answer or end calls; double-press and long-press for additional functions
• Swipe up/down on stems to adjust volume quickly
• Auto pairing for instant connection after initial setup

Who is this for? The Biyoso 5.4 Earbuds suit commuters, students and active listeners who want reliable wireless sound with simple touch controls and portable battery life—without the deep seal of in-ear tips. They’re good for hands-free calls, casual workouts and all-day listening when you need a lightweight, splash-resistant solution with USB-C convenience.
