Personally, I think it is ok to send 2.0 or 2. 1 speakers. There is no need to bring players, such as traditional CDs and DVDs, which are gradually being eliminated. If your friend's mobile phone has Bluetooth function like Apple or Android, then you can consider buying a Bluetooth speaker like Mai Bo H2 1 for six or seven hundred yuan. It looks very fashionable and high-end, suitable for home display, and can also turn the mobile phone into a wireless remote control for playing.
