Lenovo E310 True Wireless Stereo Earbuds Black (4XD1T85469) – 13mm Drivers, Bluetooth 5.3, ENC Mic, 25H Battery, Type-C

The Lenovo E310 True Wireless Stereo Earbuds (Part Number: 4XD1T85469) are engineered to deliver premium wireless audio in an ultra-portable, ergonomic design. Whether you are taking business calls on your laptop, commuting, working out, or relaxing with your favorite music playlist, the Lenovo E310 delivers crystalline sound clarity, reliable wireless stability, and long-lasting endurance.

Next-Generation Bluetooth 5.3 Connectivity

At the heart of the Lenovo E310 earbuds lies advanced Bluetooth 5.3 chipset technology. Compared to older Bluetooth generations, Bluetooth 5.3 offers significantly faster pairing speeds, higher data bandwidth, lower latency, and superior energy efficiency. Enjoy a rock-solid wireless connection with an operational range of up to 10 meters (33 feet) from your paired mobile phone, tablet, or Windows PC. Say goodbye to annoying signal dropouts during calls or lag when streaming online videos.

Powerful Sound via 13mm Hyperdynamic Drivers

Don't let the compact size fool you—the Lenovo E310 is equipped with custom-tuned 13mm hyperdynamic speaker drivers designed to deliver punchy bass, clear mid-range vocals, and crisp treble highlights. Featuring a broad frequency response range of 50 Hz to 20,000 Hz and 32-ohm impedance, these drivers ensure accurate sound reproduction across all music genres, podcasts, and video conferencing channels.

Environmental Noise Cancellation (ENC) for Crystal-Clear Calls

Communicate clearly no matter where you are. The Lenovo E310 earbuds integrate dual onboard microphones featuring Environmental Noise Cancellation (ENC) technology. ENC actively isolates your voice from ambient background sounds—such as traffic noise, office chatter, or wind—ensuring that the person on the other end hears you loud and clear during phone calls, Zoom meetings, or Microsoft Teams sessions.

Extended Playtime for All-Day Listening

Keep your soundtrack playing all day without worrying about constant recharging. The earbuds feature built-in 30 mAh batteries providing up to 5 hours of continuous audio playback or talk time on a single charge. When paired with the sleek, lightweight 280 mAh charging case, you gain an additional 20 hours of backup power, bringing total battery life to an impressive 25 hours. Recharging the case is quick and convenient via the included USB-C cable, taking just 2 hours to reach full power.

Featherweight Comfort and Intuitive Touch Controls

Weighing only 33.6 grams (case and earbuds combined), the Lenovo E310 is crafted for lightweight comfort during prolonged wear. The ergonomic in-ear contour fits securely in your ear canal without causing fatigue. Integrated smart touch controls allow you to easily manage volume, play/pause music, answer or reject calls, and trigger voice assistants with simple taps—eliminating the need to reach for your device.

Built to Lenovo’s Rigorous Quality Standards

As an authentic Lenovo product carrying commercial part number 4XD1T85469, the E310 undergoes strict testing to meet international safety and regulatory standards including CE, CB, FCC, and UN38.3. Designed to operate smoothly across temperature extremes from -20°C up to 60°C, these earbuds offer high durability and reliable performance for users across Uganda and worldwide.
