LIBRATONE AIR+3 Brand: LIBRATONE Color: Mint Green Ear Placement: In-Ear Headphone Type: Earbuds Impedance: 32 ohms Noise Control: Active Noise Cancellation [The brand's highest-level noise canceling function] With an ultra-wide bandwidth and remarkable depth, the ANC function is three times better than the previous generation model. Effectively removes noise with a design specialized for "crackling" sounds that occur when subjected to strong vibrations and "rustling" noise floors in quiet environments. Three noise-canceling modes allow you to handle various situations in everyday life. [Immersive sound & clear calls] The 11mm large-diameter dynamic driver and a radiation area four times larger than the previous generation model realize low-distortion, natural, and powerful sound. Based on classic Nordic tuning, you can enjoy sound tailored to your preferences. Dual-conduction voice enhancement technology allows for clear, uninterrupted calls wherever you are. [Premium design and comfortable fit] The AIR+3 incorporates the Scandinavian design tradition, featuring a refined triangular earbud stem and a streamlined body. Designed with ergonomics in mind, it is lightweight and fits snugly in the ear, with less pressure even when worn for long periods. The charging case adopts an open-wing design that can be opened and closed with one hand, making it easy to take out the ear tips. The integrated indicator light makes it easy to see the battery level and connected devices at a glance. [Multi-device switching] Up to 5 devices such as Android/iPhone/PC can be paired. You can smoothly switch between connected devices by touching the button on the back of the charging case or through the settings in the dedicated app. The color of the indicator light changes, allowing you to confirm the connected device. [Convenient functionality for everyday use] 6 hours of playback with the earbuds alone, up to 24 hours with the charging case / Supports USB Type-C fast charging and wireless charging / IP54 dustproof and waterproof specifications, so you can use it with confidence in sudden rain or sweat during sports / Certified with the Technical Regulations Compliance Mark. I bought it in May of this year, but it didn't fit my ears, so I used it about 3-4 times and put it away. I think the condition is good. System updates have not been performed.
