KODAK SOUNDBRIX Bluetooth Stackable Speaker - Portable 5W RMS

In this review the KODAK SOUNDBRIX is presented as a compact, stackable Bluetooth speaker aimed at casual listeners who want flexible volume scaling for parties or outdoor use. The single biggest reason to consider it is the magnetic stackable design combined with wireless multi-unit sync, which lets a user scale from a solo portable speaker to a multi-speaker setup without bulky wiring. The review looks at battery life, connectivity, water resistance and how it performs in real-world portable audio tasks.

Key Features

• Magnetic stackable design: The speakers magnetically connect so multiple units sit securely together for neat storage and combined audio output.
• 5W RMS per unit: Each SOUNDBRIX delivers a clear 5W RMS that is suitable for small rooms and outdoor gatherings when a few units are combined.
• Connect up to 100 speakers: Bluetooth 5.4 supports linking many units within a 50-meter range, which is useful for large events or synchronized outdoor setups.
• 5-hour playtime and USB-C charging: The 1200mAh battery supports up to 5 hours at full volume and the speaker recharges quickly via USB-C in about 2 hours.
• IPX4 water resistance: The IPX4 rating and a covered USB-C port provide splash protection so the speaker can be used at the beach or next to a pool with reasonable care.

Who It's For

The SOUNDBRIX suits people who need a lightweight, portable speaker that can grow with their needs: commuters, small-household owners, or anyone throwing casual parties who may want to stack two to four units for louder, fuller sound. Its magnetic stacking and one-cable charging also appeal to users who value tidy setups and easy transport.

It is less suited to audiophiles seeking high-fidelity sound at low distortion or users who need multi-day battery life for extended remote trips. Also, those who require full waterproofing for submersion should look for a higher IP rating.

Pros & Cons

Pros

• Clear advantage in scalability thanks to the magnetic stack and multi-speaker sync for louder output.
• Convenient USB-C single-cable charging that can recharge stacked units together reduces cable clutter.
• IPX4 splash resistance and a snug port cover make it practical for outdoor use in light conditions.

Cons

• Five-hour playtime at 100% volume is adequate but short for long events without recharging.
