Soundcore 3
A straightforward stereo Bluetooth speaker with USB-C charging and app-based sound adjustment. It remains a sensible option if you do not need a Wi-Fi audio system.
Benefits & things to consider
Consider it for
Simple portable Bluetooth listening
Main compromise
PartyCast linking is not the same as a true left-and-right stereo pair.
Before buying
The USB-C connection charges the speaker; it does not turn the speaker into a phone power bank.

Sonos Move 2
A home-and-garden speaker for people who want Sonos integration and can accommodate its weight. The replaceable battery and charging base suit regular use around the house.
Benefits & things to consider
Consider it for
Moving music between rooms and the garden
Main compromise
At 3kg it is less convenient for a day bag, and wired audio needs an extra adapter.
Before buying
Allow for the Sonos Line-in Adapter and audio cable if you want a wired source; these are sold separately.

We checked the exact model descriptions and published specifications, compared each choice’s practical role and reviewed relevant alternatives. We retained products where a newer name alone did not justify a change.
Our recommendations are editorial judgements based on those published differences. We have not measured performance, comfort or long-term durability. A manufacturer listing confirms a reference model, not current Amazon stock.

How to choose bluetooth speakers
Portable speaker or a room-to-garden speaker?
Picture the most common journey. Carrying a speaker in a bag is a different requirement from moving it from kitchen to patio. Compare physical dimensions and the charging setup with that journey. Sonos is particularly relevant if you also want its home Wi-Fi role.
Can you compare 12-hour and 24-hour claims directly?
Only with matching test conditions, which we have not independently established here. Volume, settings and use affect battery life. Treat the published maxima as manufacturer claims and leave a margin for your own listening instead of planning a trip to the last advertised hour.
Connectivity and weather checks
Decide whether Bluetooth alone is enough or whether home Wi-Fi features justify the extra setup. Follow each product’s water-exposure and charging instructions; a protection rating does not make every outdoor use appropriate. We have not measured loudness, bass, clarity or weather durability.
Buying check 1
Choose by where the speaker will live. Flex is the compact outdoor option; Soundcore 3 is a straightforward Bluetooth speaker; Move 2 adds Wi-Fi and Sonos integration but weighs 3kg. Manufacturer battery claims depend on volume and settings, so they are not like-for-like listening tests.
Buying check 2
Check the water-protection rating: Bose Flex is IP67, Soundcore 3 is IPX7, and Sonos Move 2 is IP56. Move 2 is not intended for immersion. Its wired audio input also needs the separately sold Sonos Line-in Adapter and an audio cable.
