Outstanding build quality ; Beefy, well-balanced sound ; Supports a wide range of streaming services and hi-res formats ; Portable with optional battery

No DLNA/uPnP support ; Clunky network sharing ; Lacks the muscle and width of larger models

Flex’s luxurious design, versatile operation and sweet sound quality live up to Bluesound’s high standards, but the lack of DLNA/uPnP makes network setup clunky

Big, open soundstage ; Solid, punchy bass ; Expressive and enthusiastic character ; Hi-res music support ; Flexible connectivity

A price increase and fresh rivals mean the Flex has lost a little ground

The Pulse Flex remains a talented member of the Bluesound family, but newer speakers have overhauled it somewhat

The Bluesound Pulse Flex offers a wealth of features and high-quality sound in a compact package. The shortcut buttons enable you to play music if you've misplaced your phone. The optional battery adds much needed, and still relatively unique, mobility.

It's more expensive than some competitors, the speaker isn't able to go very loud and sound quality is worse than the competitive Sonos product. The optional battery runs out whether playing music or not. No support for Pandora.

The Bluesound Pulse Flex is a slice of streaming hi-fi in an affordable package with an optional battery, but Sonos is better at a cheaper price.
