LG’s latest duo of TWS earbuds arrive with model numbers HBS-FN4 and HBS-FN6. The latter features an industry-first self-cleaning charging case that uses LG’s UVnano to kill bacteria as the earbuds recharge.

The UVnano works by emitting UV light onto the silicone tip and inner mesh. LG claims this is kills 99.9% of E. coli and S. aureus 2. These earbuds feature an improved design over the company’s first-generation of TWS earbuds called TONE+ Free.


The new earbuds are powered by Meridian Audio for what LG claims will offer realistic-sounding audio straight into your ear canals thanks to Meridian’s HPS (Headphone Spatial Processing) technology for immersive sound. These earbuds will use a new in-canal design for a more comfortable fit and the seal offers better noise isolation.

Both models have four EQ presets: Natural, Immersive, Bass Boost, and Treble Boost. There’s also an Ambient Sound Mode that feeds external audio into your ears so you can hear your surroundings.



The earbuds will last 6 hours on a charge and offer fast charging with a claim of 1 hour of listening with a short 5-minute charge. With the charging case, the earbuds offer a total of 18 hours of listening time.

The new TONE Free model will arrive in matte “Stylish Black” and glossy “Modern White” and begin rolling out in EU and US markets starting in July. We can expect more markets to be announced.
