Things to consider…
>>> Weatherproofing If you plan to play music away from home or at the pool, a degree of weatherproofing is advisable — maybe even essential.
>>> AirPlay AirPlay has a greater range than Bluetooth and uses lossless audio compression for higher quality. Both devices need to be on the same Wi–Fi network.
>>> Smart features Higher–end portable speakers often include “smart” features that let you do things like set timers or stream online from services like Spotify, Apple Music, and radio stations. These require a Wi–Fi internet connection .
>>> Battery life Periods of extended play will benefit from a longer–lasting battery and the ability to recharge quickly over USB.
