Review on 🎒 Budweiser Soft Cooler Bag with Built-in Rechargeable Wireless Bluetooth Speakers: Foldable, Portable, and Durable for Smartphones, Tablets & MP3 Players by Johnny Nguyen

How the cooler works well but the speakers are terrible. You're better off just using your phone's speakers. There's Bluetooth and a 3.5mm option. Both use a small black box that plugs into speakers but no amplifier, so it's just a low-pitched headache with a tinny sound. It would be great if they put a few more dollars into the amp. You can just try a cheap headphone amp and see how it works.
