Nothing Ear (a) and CMF by Nothing Buds I am selling these items because I am not using them. Nothing Ear (a) → Purchased used, the battery drains about 15% in 30 minutes. CMF by Nothing Buds → Purchased new, used for commuting for 30 minutes, 4 or 5 times. These are used items, so please refrain from bidding if you are looking for perfection or are overly concerned about details. Please be aware that there may be overlooked scratches or stains as these are used items. Accessories: None ~From the sales site~ 【Advanced Design】 Ear (a) further evolves the transparency that is characteristic of Nothing, adopting a slim and compact design. It fits comfortably in your hand and is easy to carry in your pocket or bag. Furthermore, by reviewing the placement of the earbuds, it is now easier to intuitively understand the left and right designations, and the alignment with the case opening has been improved, making it easier to use. 【Active Noise Cancellation (ANC)】 Compared to the adaptive ANC equipped on Ear (2), Ear (a) achieves noise cancellation optimized for specific scenes. By selecting the "Adaptive" mode in the Nothing X app, Ear (a) automatically adjusts the noise cancellation level (high, medium, low) according to the surrounding noise. 【Up to 45dB Noise Cancellation】 With up to 45dB of noise cancellation, the feeling of escapism is further enhanced. The most powerful noise cancellation yet provides an even more immersive experience with sound. It is now possible to respond not only to the magnitude of external noise but also to the type of noise. It covers a bandwidth of up to 5000Hz, effectively detecting and reducing annoying sounds. 【11mm Dynamic Driver】 The new 11mm dynamic driver, while more compact than the previous driver, provides 2.5 times the transient output. In addition, the innovative dual-chamber design, with the addition of two vents, improves airflow and enhances sound quality. ★Free Shipping★ #Nothing #CMF #Earphones #Wireless #apple #SONY
