When riding a mountain bike, how to listen to music is convenient. It is really inconvenient to plug headphones into a mobile phone, especially the earphone cable. Is there a better tool? Please ask God for advice. It's not easy. Directly, the last Bluetooth portable speaker can be bought with a bose and a carrying bag. It's flashy, safer than headphones, and it won't look old-fashioned when using bose. If it doesn't work, use Bluetooth headphones, but all Bluetooth headphones that listen to music better are worn. Be careful that the headphones will fall off when riding bumps. You can consider B&; O h8 has a higher face value than betas, after all, B&; O Design Kung Fu Niu X, Bluetooth version of Shantou, Sony 1abt, Senhai mm55, akg84, and some introductory Bluetooth headsets of JBL.
