UGREEN HiTune S5 True Wireless Earbuds

 UGREEN HiTune S5

The UGREEN HiTune S5 (WS210) are open-ear clip-on style true wireless earbuds designed for users who prioritize comfort, stability, and awareness of their surroundings. Unlike traditional in-ear earbuds that seal the ear canal, the S5 rests around the outer ear using a flexible ear-clip design, making them ideal for long listening sessions and active lifestyles such as running, gym workouts, commuting, or office use.

 Sound Performance

Each earbud is equipped with 12mm dynamic drivers, delivering a balanced sound profile. The audio is generally tuned toward clear vocals and mids, with slightly boosted bass, though not as deep or punchy as in-ear sealed earbuds. Because of the open design, you get a more natural, airy listening experience, but at the cost of reduced noise isolation. In noisy environments, external sounds will still be noticeable.

Support for AAC and SBC codecs helps maintain decent audio quality across Android and iOS devices, ensuring stable wireless sound transmission.

 Connectivity & Gaming Mode

The HiTune S5 uses Bluetooth 5.4, offering faster pairing, improved stability, and lower power consumption compared to older versions. It supports a low-latency gaming mode (~80ms delay), which improves sync between audio and visuals for gaming and video streaming. It also supports dual-device connection in some configurations, allowing switching between phone and laptop more easily.

 Battery Life

Battery performance is one of its strengths:

• Around 6–8 hours per charge (earbuds)
• Up to 24–32 hours total with charging case
• Fast charging support gives a few hours of playback from a short charge

The case contains a 400mAh battery, while each earbud has a 40mAh cell, which is typical for this category.

 Calls & Controls

The earbuds include dual microphones with AI noise reduction, improving voice clarity during calls by filtering background noise like wind or traffic. Touch controls allow you to manage music, calls, voice assistant, and gaming mode directly from the earbuds.

 Build & Comfort

They feature an IPX5 water-resistance rating, making them safe for sweat and light rain. Each earbud is lightweight (~4g), and the ear-clip design ensures a secure fit without pressure inside the ear canal—great for users who dislike in-ear discomfort.
