UGREEN has introduced the HiTune S6 Pro in China, and the standout detail is not just the open-ear design. At 199 yuan, the new wireless earphone pairs spatial audio with a clip-on fit that is usually seen in more expensive products.
The model is aimed at users who want longer listening sessions without fully blocking outside sound. That approach makes it suitable for work, workouts, and daily travel, where staying aware of the environment can matter as much as the audio itself.
Open-ear design built for comfort
The HiTune S6 Pro uses an open-ear clip-on structure with an ergonomic C-bridge design. UGREEN also fits it with a 0.6 mm memory titanium wire to help keep the earphone stable while remaining light on the ear.
Because it does not sit fully inside the ear canal, this type of design is often chosen to reduce fatigue during extended use. UGREEN positions that comfort advantage as one of the product’s main selling points, along with everyday practicality.
Audio features go beyond the price tag
On the sound side, the earphone comes with a 12 mm dynamic driver. It supports AAC and SBC codecs, while spatial audio is included to create a more immersive listening experience.
UGREEN has also added a directional sound transmission mode. The feature is meant to reduce sound leakage and improve privacy when the earphones are used in public spaces.
Bluetooth 6.0 and built-in AI support
For wireless connectivity, the HiTune S6 Pro uses Bluetooth 6.0 and is rated for up to 10 meters in open, unobstructed areas. The earphones also include a free lifelong AI assistant, giving users access to voice-based interaction through the device.
The combination of Bluetooth 6.0, voice control, and an open-ear form factor shows how UGREEN is targeting more than comfort alone. It is also aiming at users who increasingly rely on always-connected devices and quick voice commands.
Durability is covered by an IPX5 rating, which makes the earphones suitable for exercise, outdoor use, and routine commuting. That makes the HiTune S6 Pro more practical for users who need a lightweight audio device that can handle everyday movement.
Battery life is another major advantage
Battery performance is another highlight. UGREEN says the HiTune S6 Pro can play audio for up to 9.5 hours on a single charge.
With the charging case included, total battery life reaches around 48 hours. That figure places the model in a competitive position for users who prefer not to recharge their wireless audio gear too often.
Each earbud carries a 50 mAh battery, while the charging case includes a 580 mAh battery and uses a USB Type-C port. A full charge reportedly takes about 1.5 hours, which supports a mobile lifestyle with frequent use throughout the day.
The charging case measures 77.5 × 66.3 × 26.8 mm, and the product weight is about 55 grams. The full retail package weighs around 128 grams, with packaging dimensions listed at 118 × 92 × 36 mm.
Price and availability
The full product name is UGREEN HiTune S6 Pro True Wireless Bluetooth Earphones, and the model number is WS221. It is currently available in China in a single color option, Starlight Silver.
UGREEN also includes a one-year warranty with the product. At 199 yuan, the HiTune S6 Pro is clearly positioned as an affordable option for buyers who want open-ear earphones with spatial audio, Bluetooth 6.0, IPX5 protection, and long battery life in one package.
