Thank you very much for viewing! This is a brand new, unused item. Please let me know if you have any questions or requests in the comments section. Returns are not accepted to prevent issues such as product switching. [Evolved from customer feedback! The latest version is highly recommended for open-ear headphones] [Improvement ①: Even more comfortable fit!] The ear hooks of the previous model were thick and hard, which often caused ear pain after long periods of use. The latest version uses soft silicone material, which is gentle on the ears and less tiring even after long periods of use. [Improvement ②: Significantly enhanced sound quality!] The previous model had weak three-dimensionality and resolution. The latest version features Hi-Fi class clear sound, making it possible to accurately reproduce even the sound of footsteps in games. [Improvement ③: Clearer calls!] The conventional normal microphone tends to pick up ambient noise. The latest version features an AI-equipped ENC (Environmental Noise Cancellation) microphone that suppresses wind and noise, conveying only your voice clearly. [You'll understand once you use it! Refreshing wearing comfort] Because they are open-ear and do not block the ears, there is no discomfort from listening fatigue or stuffiness in the ears, and they can be used lightly and comfortably for long periods of time. The air conduction method causes less discomfort than bone conduction, and is recommended for those who are not used to bone conduction. [Perfect for listening while doing other things! Headphones that don't block your ears] Peace of mind knowing you can hear your surroundings. Because you can still hear the sounds around you even while wearing the headphones, you don't have to worry about missing calls while doing housework or working, and you can quickly notice approaching cars, train announcements, and emergency alarms when you're out and about. Also, you can have a smooth conversation without taking off your headphones! [Stable fit and difficult to fall off! Ear-hook headphones] The lightweight design fits snugly on the ears, providing a stable fit even during running or exercise. The ear hook shape is also well-designed and does not interfere with glasses or masks. [Ultra-lightweight model with zero "wearing feel"] The ultra-lightweight type weighs only 9g for both ears, reducing the burden on the ears and allowing for comfortable use even for long periods of time. [The appeal of "ready to use" wired headphones] No pairing required, no Bluetooth settings required, no charging required. Just plug in the cable and you can use it anytime, anywhere. [Highly versatile 3.5mm stereo mini plug] Widely compatible with laptops, smartphones, tablets, radios, etc. Cord length 1.2m. It is useful in various situations such as music, programs, live streaming, audiobooks, classes, commuting to school, etc. [Convenient remote control included] Volume adjustment, play/pause, track forward/backward, call answer/reject, voice assistant activation, etc., all can be easily operated with the remote control!
