We want to create an audio product that can enjoy a variety of high-quality audio content simply by turning it on. There is no need to connect a mobile phone or perform any other operations while playing, and there is an independent network source to start listening immediately. At present, many audio products on the market take simple aesthetics as the first, often at the expense of functionality. But all functions of this product are controlled by mechanical buttons and knobs, and equipped with tactile mechanical feedback, which is very convenient to use.
