- Open-Ear First “Open-Ear Noise Reduction”: OpenFit Pro identifies ambient noise with 3 microphones and AI algorithms, and reproduces anti-phase sound waves through speakers to partially cancel indoor noise, implementing the world's first open-type noise reduction mode[101][102]. It is not as quiet as fully sealed ANC, but it greatly reduces air conditioning/people's murmuring in a cafe, increasing music immersion while allowing people's voices to be heard to some extent, maintaining situational awareness[103].
- Dolby Atmos Support with Dual Speakers: Equipped with a total of 4 speaker units, 2 per earbud, it plays Dolby Atmos 3D audio for the first time in open-type earphones[104]. Compared to the general OpenFit 2+, the speaker unit is larger and separated into 2-way, producing rich sound without distortion from low to high frequencies[105]. It is said that it overcomes the limitations of the open form factor because you can fully enjoy the immersive sound effects when watching movies or playing games.
- User Manual Adjustment Available: The noise reduction level can be manually set through the app, allowing the user to decide the degree of noise cancellation depending on the situation[102]. For example, set the level to maximum at home for quietness, or turn off the function and use full open mode when running outdoors. With this flexible control, a single pair of earphones can respond to various environments.
- Improved Battery and Water Resistance: Despite the noise reduction function, the battery has been increased by 1 hour to 11 hours (28 hours including the case) compared to OpenFit 2[101], and it is resistant to sweat and rain with IPX5 water resistance. This is made possible by high component integration and improved power efficiency, making it a perfect premium exercise earbud.
