I'm over the moon with this thing. Over the past year I have used: JBL Flip 4, UE Boom 3, Sonos Roam, and the Bose Soundlink Revolve. Everything else is a pretender compared to the Revolve as far as sound quality goes, but the Revolve is not quite as porable as I want and still is stuck with micro usb. I bought the Soundlink Flex on the day it was released because I needed something that I could tote around but I still wanted to have good sound at all volumes.

This is the BEST speaker EVER! Great sound quality even when you have it at max volume~battery life is also amazing! I haven’t actually checked the battery life per my listening but it lasts forever..all day of cleaning and working out into the nite sitting outside by the fire. I LOVE it and highly recommend!

Excellent little speaker for the price. Sounds great. My favorite feature is Party Mode. Using the Bose Connect app, I’m able to connect multiple Bose speakers. This allows me to stream a podcast in multiple rooms, which comes in handy when working around the house. I especially like to set one of these speakers on opposite sides of the kitchen when I’m batch cooking. I’m literally surrounded by music, making the chore go faster.

They claim up to 12 hours battery life. Maybe if you have it turned all the way down. At a loud volume, not even close. I can’t make it through an 8 hour day at full volume. Bose needs to claim real world battery life’s on all their products none of this “up to a certain amount”

Incredible sound from such a small speaker! I use in my large shop daily and it fills the room. I a So have an older sound link; it's good but this one is much better.
