TRAUSI i27 Wireless Earbuds Bluetooth 5.4

TRAUSI i27 wireless earbuds are lightweight Bluetooth 5.4 earphones with up to 54 hours total playtime, IPX7 splash resistance, noise‑reducing microphone, and fast charging for workouts and travel.

These compact earbuds combine stable wireless connectivity, comfortable sport-focused design, and a charging case that extends single-charge listening into multiple days. They pair automatically, support common Bluetooth profiles for low-latency audio, and include touch controls so you can manage music and calls without reaching for your phone. The i27 aims to balance long battery life with a secure fit for active use.

How clear is the sound and will calls come through reliably?

The i27 uses Bluetooth 5.4 with true wireless stereo to deliver clear, balanced audio and consistent pairing between left and right buds. A built-in noise‑cancelling microphone reduces ambient noise, improving voice clarity for calls in busy environments. You won’t get studio-level isolation, but voice and media playback are tuned for everyday use.

• Bluetooth 5.4 for stable transmission and reduced dropouts
• True wireless stereo for synchronized left/right channels
• Noise‑cancelling mic for clearer phone conversations
• Compatible with iOS, Android, and Windows devices

Will they stay comfortable and secure during exercise?

The earbuds weigh about 7 g each and include soft earhooks plus three silicone tip sizes to fit different ear shapes. An IPX7 water resistance rating protects them from sweat, rain, and splashes—suitable for running, gym sessions, and outdoor workouts. Note that IPX7 resists immersion-related damage but isn’t intended for swimming.

• Ultra-light earhook design for a snug, stable fit
• S/M/L silicone ear tips for custom comfort
• IPX7 rating for sweat and rain protection
• Slim profile that stays put during movement

How long does the battery last and how fast does it charge?

A single charge provides about 6 hours of playback per earbud; the compact 400 mAh case boosts total playtime to roughly 54 hours. The case recharges via USB-C in about 1.5 hours, and a 10-minute quick charge gives approximately 2 hours of listening—handy before a short trip or workout. An LED percentage display on the case helps you track remaining power at a glance.

• 6 hours per charge, 54 hours total with charging case
• 400 mAh charging case with USB-C fast recharge
• 10-minute quick charge ≈ 2 hours playback
• LED percentage display for accurate battery status

How easy is it to connect and control the earbuds?

Take the earbuds out of the case and they automatically power on and attempt pairing, making setup almost effortless. Touch controls allow play/pause, track skip, volume adjustments, and voice assistant activation—so you can stay hands‑free while on the move. The buds support HSP, HFP, A2DP and AVRCP profiles for broad device compatibility.

• Auto power-on and instant pairing on removal from case
• Smart touch controls for music, calls, and voice assistants
• Dual-channel transmission for stable left/right audio
• Up to 15 m (50 ft) wireless range in open space
