Bluetooth speakers are very popular in China, and there is a big selection of different models. Whereas the high-end area is mostly dominated by brands such as Bose and JBL, Chinese brands dominate the low budget and middle-class range (20-50$) with a great price-performance-ratio. Aukey and Anker are two of the well-known names. Sometimes you can get a really nice sound already from 30$ onwards. For the more eccentric users there are also speakers with integrated LED lights available.
