UGREEN LightBuds True Wireless Earbuds

The UGREEN LightBuds (model WS217, SKU 65876) are true wireless in-ear earbuds built around a 13mm dynamic driver with N48 Neo magnet and UGREEN Golden Sound tuning, connecting via Bluetooth 6.0 for improved stability and power efficiency over earlier Bluetooth generations. They deliver up to 6.5 hours of playback per charge and 35 hours combined with the charging case, pair to two devices simultaneously, and adapt their audio output to the wearer’s ear shape and environment through Smart Sound Boost technology. A four-microphone ENC system with a directional call algorithm maintains call clarity in noisy surroundings, and a low-latency gaming mode reduces audio delay to 80ms for improved synchronisation during video and gaming use. IPX5 water resistance covers everyday sweat and light rain, making them practical for commuting and light fitness use.

Bluetooth 6.0 — What the Upgrade Means

Bluetooth 6.0 is the most recent generation of the Bluetooth standard. Compared to Bluetooth 5.4 used in the HiTune T3 Pro, version 6.0 introduces Channel Sounding — a distance and positioning feature — as well as further improvements to co-existence with Wi-Fi 6 and 6GHz spectrum bands, reduced transmission overhead, and enhanced connection management for multi-device scenarios. In practical terms, Bluetooth 6.0 earbuds benefit from a more stable connection in environments with dense wireless traffic — offices, airports, and urban commutes where Bluetooth and Wi-Fi interference is high — and from marginally improved power efficiency that contributes to the 35-hour total battery runtime.

Smart Sound Boost: Adaptive Audio Compensation

Most earbuds deliver the same equalisation profile regardless of how they sit in the ear, what ear tip size is used, or whether the wearer is in a quiet room or a crowded street. Smart Sound Boost addresses this by analysing three variables in real time: the fit of the earbud in the ear (detecting the seal quality of the ear tip), the wearing orientation, and the external acoustic environment. The algorithm then adjusts the audio output to compensate, maintaining consistent perceived sound quality regardless of these variables. Furthermore, Spatial Audio processing runs at 48,000 detections per second to maintain 3D positional balance, creating a wider soundstage than standard stereo earbuds of equivalent driver size produce.

Use Cases & Applications

Daily Commuting and All-Day Listening

At 35 hours combined, the LightBuds cover a full working week of commuting and desk listening on a single case charge — charging the earbuds back up each time they return to the case overnight. The 10-minute fast charge contingency handles the common scenario of discovering a flat earbud before leaving home, providing 90 minutes of playback from a brief morning charge. Bluetooth 6.0’s improved co-existence with dense wireless environments is particularly relevant on public transport and in urban areas where Bluetooth interference is highest.

Calls in Noisy Environments

The 4-mic ENC system with directional algorithm targets the primary weakness of standard 2-mic earbuds: their inability to distinguish the speaker’s voice from ambient noise at angles other than directly in front of the microphone. By combining two microphones per earbud with a directional processing algorithm, the LightBuds maintain clear call pickup from multiple sound source angles — useful for calls taken while walking, in transit, or in open-plan offices where noise arrives from multiple directions simultaneously.

Gaming and Video Streaming

The 80ms gaming mode latency reduces the audio-visual desynchronisation that standard Bluetooth introduces during video playback and gaming. For mobile gaming and video streaming on a phone or tablet, the gap between an on-screen event and its audio counterpart at 80ms is at or near the threshold of perception — providing a noticeably more natural viewing and gaming experience compared to standard Bluetooth AAC latency of 150–200ms. The mode is accessible via touch control on the right earbud.

Personalised Listening via App

The 8 preset EQ modes through the UGREEN Home app allow the LightBuds to adapt to different listening scenarios without requiring manual EQ adjustment: Bass Up for workout playlists, Classic for orchestral listening, Jazz for vocal-heavy content, and Electronic for synthesised music. The Find My Earbuds feature provides a practical safeguard against misplaced earbuds, triggering an audible tone through the app when the earbuds are within Bluetooth range.
