HMD is preparing to expand its DUB series of TWS earphones just weeks after launching six models. The company shared a teaser image on X that suggests the new earbuds will mirror the design of the DUB X50 Pro, which debuted last month with an in-ear form factor and IPX4 water resistance.

The DUB X50 Pro features active noise cancellation and Hi-fi DSP for audio processing. Each earbud contains a 70 mAh battery, while the charging case holds 600 mAh, delivering up to 60 hours of total playback at 50% volume. HMD's rapid expansion into affordable audio follows its recent push into feature phones and rugged enterprise devices.

HMD has not confirmed the new model's name or launch date, but the teaser indicates another addition to its growing portfolio. With the TWS market crowded, HMD's strategy focuses on value-oriented features like ANC and long battery life. Watch for an official announcement in the coming weeks as the company battles established audio brands.
