What to know before buying

Listing details to confirm

The listing is inconsistent about stereo presentation: it calls this one speaker 360° stereo, while its dual-speaker pairing claim describes a 120W stereo setup with a second unit. The title and feature text cite IPX8, but the listing provides no test conditions. Battery life and charging time are unconfirmed. Check the selected listing for these details before relying on them.

Customer feedback reports favorable impressions of sound clarity, ease of use, portability, connectivity and volume. Battery-life experiences are mixed, with some finding it long-lasting and others less satisfied. For portable use, the compact listed size is relevant, but the listing gives no runtime, so feedback does not resolve whether it will last through a particular outing.

Mixed feedback

Frequently asked questions

Can the S620 pair with another speaker?

The listing says two speakers can pair for a claimed 120W stereo setup. That claim requires a second unit and does not establish the single speaker's stereo performance.

What is the stated waterproof rating?

The title and feature copy state IPX8. The listing does not give test conditions, so do not assume a particular depth or duration of water exposure.

How long does the battery last?

The supplied details do not state a battery runtime or charging time. Check the selected listing if either is important for your use.

Does it support playback without Bluetooth?

The feature copy claims a TF card input in addition to Bluetooth. Confirm the selected listing if card playback is essential.
