Anker Soundcore Motion Boom
Built Around Being Carried
It has a moulded handle across the top, which sounds trivial and changes how a speaker of this size is actually used. A speaker with a handle gets picked up and taken to the garden, the beach or a campsite; one without gets carried awkwardly under an arm or left where it is.
It also floats, which along with its water rating means the usual outdoor hazards — rain, spray, being knocked into water — are covered rather than survived.
The combination of handle, buoyancy and water resistance is what defines it as outdoor equipment rather than a shelf speaker that tolerates a garden.
Battery Life And Power Output
Battery life is long, comfortably covering a day outdoors at reasonable volume, and there is a USB output for charging a phone from the speaker's battery.
As with any speaker offering this, charging a phone consumes playback time, and it is best thought of as an emergency top-up rather than a substitute for a power bank on a long day.
Charging is over USB-C, and the port cover needs to be closed properly for the water rating to mean anything — an open flap is the commonest way a waterproof speaker is no longer waterproof.
Sound At The Price
The tuning is bass-forward, which is the right choice for outdoors where there are no walls to reinforce low frequencies, and it can sound heavy indoors in a small room.
Volume is good for the size and sufficient for a garden gathering, and at maximum it compresses rather than distorting badly.
It is not a refined speaker and it does not need to be. At this price and for this use, loud, bass-forward and robust is the correct set of priorities, and detail and neutrality are reasonable things to trade away.
App And Titanium Drivers
There is an app with equalisation and a bass-boost mode, which is worth using to tame the low end when the speaker is indoors.
The drivers are described as titanium, which in practice means a stiff diaphragm material that helps the top end stay clear at volume. It is a real material choice rather than marketing, and its effect is modest.
App dependency is light here — the speaker functions fully without it and the app adds equalisation rather than core function, which is the right balance.
Against The Alternatives
Against a JBL Charge 5, the Motion Boom is cheaper, has a handle and floats; the JBL is more refined and better built.
Against a UE WONDERBOOM, this is much larger and louder with a handle and a power output; the UE fits anywhere.
Against premium portables, the gap is finish and refinement rather than function, and the price difference is substantial.
The Verdict
Well-judged outdoor equipment: a handle that means it actually gets carried, buoyancy and water resistance that cover real hazards, long battery and a useful power output, at a sensible price.
It is bass-heavy indoors, not a refined speaker, and the port cover must be closed for the water rating to apply.
Close the charging port flap properly — an open cover is the commonest reason a waterproof speaker stops being waterproof.
At a glance

- Floats and is water resistant; covers real outdoor hazards
- Long battery life with a USB output for phones
- Considerably cheaper than premium rivals
Cons
- Bass-heavy and boomy indoors
- Not a refined speaker; detail and neutrality traded away
- Water rating depends on the port cover being closed
- Build and finish below premium alternatives
Frequently asked questions
Why does a handle matter?
Because a speaker of this size without one gets carried awkwardly under an arm and therefore often stays where it is. A handle means it goes to the garden, the beach and the campsite, which is the entire point of an outdoor speaker.
Is it still waterproof if I forget the flap?
No, and that is the commonest way a waterproof speaker stops being waterproof. The rating assumes the charging port cover is properly closed and seated, and checking it before taking the speaker near water is a habit worth forming.
How does it compare with pricier rivals?
The gap is finish and refinement rather than function — it is loud, floats, lasts a day and charges your phone. For outdoor use where speakers get knocked about, spending less on something you worry about less is a reasonable argument.
