What to know before buying

Listing details to confirm

Listing details are inconsistent on Bluetooth version: the title says Bluetooth 5.0, while a feature claim says Bluetooth 5.3. The two-S1-Pro pairing feature is claimed, but the package contents do not confirm a second speaker. The runtime claim is conditional on volume, lighting and music type, and the product description's immersion claim does not specify a duration.

Who is it for?

A good fit for

Listeners wanting a portable speaker with listed stereo output and selectable EQ modes.
Buyers looking for a speaker described for poolside, shower or outdoor use who will observe the stated water-resistance conditions.
People who want RGB lighting and the option to pair two S1 Pro speakers.

Less suited to

Buyers who need a confirmed Bluetooth version before ordering.
Anyone relying on 30 hours of playtime regardless of volume, lighting or music choice.

Customer feedback highlights loud, powerful sound, battery life, Bluetooth connectivity, ease of use and colour-changing lights. Some feedback also reports that the speaker stops working, so functionality is not uniformly positive. These are reported perceptions, not confirmation of the listing's 40W output or stated battery runtime. For outdoor listening, the stated IPX7 claim and the conditional runtime are relevant features to weigh alongside the mixed functionality feedback.

Positive themes

Customers praise sound quality and volume, and report positive experiences with battery life, Bluetooth connectivity and ease of use.
Customers also appreciate the colour-changing lights.

Negative themes

Some customers report that the speaker stops working.

Mixed feedback

Functionality receives mixed feedback.

Frequently asked questions

How long does the RIENOK S1 Pro battery last?

The listing states 30 hours, but its feature text qualifies this as up to 30 hours and says runtime varies with volume, lighting and music type.

Which Bluetooth version does this speaker use?

The listing conflicts: its title says Bluetooth 5.0 and a feature claim says Bluetooth 5.3. Confirm the version with the selected listing before buying if it matters to you.

Can two speakers be paired together?

The description claims two S1 Pro speakers can be paired. It does not confirm that a second speaker is included in this product's package.

Is the speaker waterproof?

The listing claims IPX7 and says it can be immersed in 1 metre of water. It does not state an immersion duration, so follow the manufacturer's instructions.
