When you already have the BOSE S1 PRO+, this thing, along with the version for musical instruments, is absolutely great. Battery life is 5+ hours, very easy to operate, and it pairs instantly in any slot. The build quality feels a bit cheaper – for the price – but I think it will last. The only thing I would appreciate – even if it meant connecting to power via a power bank – is phantom power, which is simply missing on the BOSE speaker itself. But otherwise, I highly recommend it.
