The speaker is suitable for everyday listening, including:
🎵 Music

The larger driver helps the compact speaker deliver an engaging sound experience while maintaining its portable form factor.
🔊 360° Surround Sound
One of the key features of the Thinkplus K3 Plus is its 360° full-frequency sound field.
Instead of directing sound primarily toward one side, the speaker is designed to provide a more spacious listening experience around the unit.
This makes it useful when multiple people are listening from different positions around a room or table.
🌈 7 Colorful RGB Light Modes
Make your music setup more attractive with the built-in 7-color RGB lighting.
The K3 Plus offers multiple colorful lighting effects that can add a vibrant atmosphere to your:
Gaming desk
Bedroom

The RGB lighting is one of the main visual features of the K3 Plus and makes it different from conventional portable Bluetooth speakers.
📡 Wireless Bluetooth Connectivity
Connect your smartphone, tablet, laptop or other compatible device wirelessly.
The K3 Plus supports Bluetooth connectivity with a commonly listed operating range of around 8–10 meters, depending on the environment and obstacles.
The user manual identifies the K3 Plus Bluetooth version as 5.2 and states a transmission distance of at least approximately 10 meters under suitable conditions.

Some current specifications list support for TF cards up to 32GB.
🔋 500mAh Rechargeable Battery
The speaker is powered by a built-in 500mAh rechargeable battery.
This makes the K3 Plus suitable for portable everyday use without needing a continuous power connection.
Published specifications vary on exact playback time depending on the version/source, with some listings reporting approximately 6–8 hours and the K3 Plus manual specifying a shorter figure under its test conditions.
Actual battery performance depends on:
Volume level
RGB lighting usage
Bluetooth connection
Music type
Battery condition
Usage environment
🔌 Convenient Type-C Charging

🪶 Compact & Portable Design
The K3 Plus is designed to be compact and easy to carry.
A current Bangladesh listing gives approximate product dimensions of 8 × 8 × 7.4 cm, making it convenient for desks, shelves and portable use.
Its compact size means you can easily move it between:
Bedroom → Office → Desk → Living Room → Travel
🔗 Connect Two Speakers for Stereo Sound
The K3 Plus supports pairing two compatible speakers for a wider stereo/surround experience according to current product documentation and listings.
If you have two compatible units, this feature can help create a more immersive listening setup.
💧 Water-Resistance Information
Some Bangladesh seller listings describe the K3 Plus as splash-resistant or life waterproof, but the available user manual specifically warns that the product should not be exposed to liquid.
Therefore, for your Rosen Mart product page, I recommend not claiming “waterproof” or an IP rating unless your actual product packaging confirms it.
This is important because inaccurate waterproof claims can create customer complaints and return issues.
