Product Overview
The Soundcore Select 4 Go is a compact, battery-powered Bluetooth speaker in Soundcore’s portable audio range. It uses a single full-range driver with a passive radiator and produces mono audio when operated as one speaker. Two compatible Select 4 Go units can be linked through True Wireless Stereo mode to create separate left and right audio channels.
The enclosure carries an IP67 ingress-protection rating for resistance to dust and temporary water immersion. Its floating design, built-in attachment point, and carrying strap support use around pools, showers, campsites, and other locations where a compact portable speaker may be useful. Wireless playback is provided through Bluetooth, with a stated operating range of up to 30 meters under suitable conditions.
The internal rechargeable battery provides up to 20 hours of playback under the manufacturer’s specified test conditions. Sound settings, firmware functions, and battery information can also be accessed through the Soundcore mobile app. The speaker supports customizable equalizer settings and physical controls for common playback functions.

Common Uses
The Select 4 Go is designed for portable wireless audio from Bluetooth-equipped phones, tablets, computers, and similar playback devices. Its compact enclosure and carrying strap allow it to be moved between rooms or transported in a backpack or travel bag.
- Listening to music, podcasts, and other audio from a mobile device
- Audio playback in bathrooms and showers
- Poolside and beach use within the limits of its water-resistance rating
- Camping, hiking, picnics, and other outdoor activities
- Temporary audio playback in bedrooms, offices, hotel rooms, and similar spaces
Maintenance and Care
Keep the charging-port cover fully closed before exposing the speaker to water or dusty environments. If the speaker becomes wet, remove surface moisture and allow it to dry before opening the charging cover or connecting a cable.
Clean the exterior with a soft cloth and avoid abrasive cleaners or solvents. Store the speaker in a dry, ventilated location when it will not be used for an extended period. Periodic charging helps prevent prolonged storage with a completely discharged battery.
Safety Information
The speaker carries an IP67 ingress-protection rating. This rating covers dust protection and temporary freshwater immersion under standardized test conditions; it does not make the device resistant to every liquid, pressure level, or environmental condition.
- Close the charging-port cover securely before water exposure.
- Do not charge the speaker while the charging connector or port is wet.
- Keep charging equipment away from water.
- Avoid exposing the internal rechargeable battery to excessive heat, fire, puncture, or crushing.
- Use charging equipment that provides the electrical input specified for the speaker.

Product History
The Soundcore Select 4 Go was introduced in 2024 as a compact model within Soundcore’s portable Bluetooth speaker range. It was positioned below larger portable speakers while retaining features such as water and dust resistance, app-based equalization, and stereo pairing.
Soundcore later documented a hardware revision of the Select 4 Go. The newer hardware uses Bluetooth 6.0, while earlier production units use an earlier Bluetooth implementation. Soundcore states that True Wireless Stereo pairing requires two speakers from the same hardware version, so older and newer revisions cannot form a TWS pair with each other.
Key Features
- Compact enclosure with integrated attachment point and carrying strap
- IP67-rated resistance to dust and temporary water immersion
- Floating enclosure for use around water
- Soundcore app support for sound adjustment and device functions
- Customizable equalizer settings
- True Wireless Stereo capability using two compatible units
- Physical buttons for Bluetooth and playback controls
- Rechargeable internal battery for cordless operation
Package Contents

A wall charging adapter is not included with the documented package configuration.
Compatibility
The speaker connects to devices capable of standard Bluetooth audio output, including compatible smartphones, tablets, laptops, and desktop computers. The Soundcore mobile app provides access to additional device controls and equalizer settings on supported mobile platforms.
True Wireless Stereo requires a second compatible Select 4 Go speaker. Hardware revisions must match for TWS pairing. Users trying to pair two units should check the Bluetooth version stated in each speaker’s documentation when determining whether the revisions are compatible.
Frequently Asked Questions
How do I identify the Soundcore Select 4 Go model?
Check the product label, packaging, or user documentation for the model designation. This information is useful when locating the correct support documentation or checking hardware compatibility.
Can the Select 4 Go be used in a shower?
Its IP67 enclosure is designed to resist dust and temporary water immersion when the protective charging-port cover is properly closed. Charging connections should remain dry.
Can two Select 4 Go speakers play in stereo?
Yes. Two compatible units can use True Wireless Stereo to operate as separate left and right channels. Speakers from different hardware revisions may not pair with each other in TWS mode.
How can I determine which hardware revision I have?
Soundcore advises checking the Bluetooth version listed in the supplied quick-start guide or user guide. Documentation showing Bluetooth 6.0 identifies the newer hardware revision.
Does the speaker require an application for normal playback?
No. Standard Bluetooth pairing and playback can be performed without the mobile application. The app adds functions such as equalizer adjustment and device management.
How should the speaker be dried after water exposure?
Remove visible moisture and allow the exterior and charging area to dry before opening the protective port cover or connecting a charging cable.
Can the speaker remain permanently submerged?
No. An IP67 rating covers temporary immersion under defined test conditions. It is not a rating for continuous underwater operation.
Does it have a replaceable battery?
The product is designed around an internal rechargeable battery rather than a routine user-replaceable battery system.
What warranty is documented for this model?
A 24-month warranty is documented for the product. Warranty coverage can depend on region, seller, purchase documentation, and applicable warranty terms.
Buying Considerations
The Select 4 Go is a small single-driver speaker, so its acoustic output and low-frequency extension differ from larger multi-driver portable speakers. A single unit produces mono sound; stereo reproduction requires a second compatible speaker.
Users planning to pair two units should verify that both speakers belong to the same hardware revision. Battery runtime also varies with playback volume, equalizer settings, audio content, connection conditions, and battery age, so the maximum stated runtime should not be interpreted as a fixed result under every use condition.
The speaker relies primarily on Bluetooth for source audio. Users requiring specialized wired inputs or larger multi-speaker synchronization systems should compare connection requirements with the features supported by this model.
Customer Feedback Summary
This section summarizes recurring themes found in publicly available customer and independent user feedback. These observations are generalized reports and are not verified product specifications or results from personal testing.
Frequently positive themes include the speaker’s compact size, low carrying weight, straightforward Bluetooth pairing, water-resistant construction, and battery endurance during moderate-volume listening. Users also commonly mention that the Soundcore app and adjustable equalizer provide more sound control than expected from a small portable speaker.
Reported limitations generally relate to the physical constraints of a compact single-driver design. Some listeners describe limited deep bass, reduced fullness compared with larger speakers, and less even sound when listening from certain angles. Independent testing has also noted that one unit remains a mono speaker and that perceived battery duration can differ significantly with volume and equalizer settings. Occasional connection issues have also been reported in some public user accounts.
