Ultimate Ears MEGABLAST Portable Wi-Fi / Bluetooth Speaker with hands-free Amazon Alexa voice control (waterproof) – Graphite $125

Best price i have seen for this big boy. I have this and sounds great. You can’t pair it with other speakers though.
I am guessing this won’t last long as it is a very solid price.
