It uses Bluetooth 5.3 for wireless connections and also supports a 3.5 mm auxiliary input and TF memory cards. The speaker provides 15 watts of continuous output, with a stated peak output of 20 watts.
An IPX5 water-resistance rating provides protection against water jets and common splashes, allowing the speaker to be used in many indoor and outdoor environments. Integrated LED lighting can operate while music is playing, and two compatible PulseSound speakers can be linked through True Wireless Stereo pairing. A built-in microphone supports hands-free voice calls when connected to a compatible device.

Maintenance and Care
Clean the exterior with a soft, lightly dampened cloth. Abrasive materials and aggressive chemical cleaners should be avoided because they can damage the enclosure or controls.
Keep the protective port area properly closed when the speaker may be exposed to water. Store the speaker in a dry location away from prolonged direct sunlight and extreme temperatures. Recharge the internal battery periodically during extended storage rather than leaving it fully discharged for long periods.
Safety Information
The speaker carries an IPX5 water-resistance rating. IPX5 protection is intended for water jets and splashes and does not indicate protection for continuous underwater use or submersion.
- Do not intentionally submerge the speaker in water.
- Keep charging connections dry before connecting a charging cable.
- Use suitable USB charging equipment with the supplied charging cable.
- Avoid exposing the rechargeable battery to excessive heat, fire, or extreme temperatures.
- Do not attempt to open, puncture, or modify the internal battery.

Frequently Asked Questions
What model name should appear when identifying this speaker?
The verified model name is PulseSound. This name can be useful when checking Bluetooth connections, documentation, or product support information.
Can the speaker be used around a pool or outdoors?
Its IPX5 rating provides resistance to splashing and water jets. The rating does not mean the speaker can be safely submerged in water.
Can two PulseSound speakers operate together?
Yes. True Wireless Stereo functionality allows two compatible units to be linked for separate left and right audio channels.
Does the speaker require Bluetooth for all audio playback?
No. It also provides auxiliary input and TF card playback, allowing audio to be used without an active Bluetooth connection.
Can the LED lighting be controlled separately from playback?
The speaker provides selectable lighting operation through its physical controls, including the ability to change lighting modes or turn the lighting off.
Does it work with a laptop or desktop computer?
It can work with computers that provide compatible Bluetooth audio output. A compatible wired audio connection may also be used where supported.
How should the speaker be cleaned?
Use a soft cloth that is dry or lightly dampened. Avoid abrasive cleaners, solvents, or other chemicals that could damage the housing.
Does the speaker include a replaceable battery?
The product uses an internal rechargeable battery. Public documentation does not identify the battery as a routine user-replaceable component.
What warranty is supplied with the product?
Public product information identifies a limited warranty. Warranty coverage and service procedures can depend on the specific distribution channel and region.
Buying Considerations
Users comparing portable speakers may want to consider the PulseSound’s compact format, output level, available input methods, water-resistance classification, lighting functions, and rechargeable battery design. TWS functionality requires a second compatible speaker if stereo pairing is desired.
The IPX5 rating should also be distinguished from higher water-resistance classifications intended for temporary submersion. Battery runtime figures represent rated maximum operation and can vary with volume level, lighting use, wireless conditions, battery age, and other operating factors.
Customer Feedback Summary
This section summarizes recurring themes found in publicly available customer feedback. These observations are subjective reports and are not verified technical specifications.
Common positive themes include the speaker’s sound output relative to its compact enclosure, simple Bluetooth pairing, portability, and integrated lighting. Users also frequently mention the rechargeable battery, carrying strap, and multiple playback methods as useful practical features.
Reported limitations include expectations around bass depth and maximum-volume performance compared with physically larger speakers. Battery runtime can also vary according to listening volume and lighting use. Some users may prefer stronger water protection when equipment will be used in situations where full immersion is possible.
