The SoundLink Flex (2nd Gen) Bluetooth speaker promises big sound in a small, durable package. After weeks of testing in various environments, from backyard barbecues to hiking trails, I’m ready to share my comprehensive review of this portable audio powerhouse. The model number, 887612-0300, is prominently featured in the marketing, so that’s what I’ll refer to throughout this review.

The SoundLink Flex boasts several key features designed for on-the-go listening. Its compact size and included utility loop make it incredibly portable, easily attaching to backpacks or bags. The IP67 rating ensures it’s waterproof and dustproof, surviving splashes, rain, and even accidental drops. The advertised 12-hour battery life is a significant selling point for extended outdoor use, and the integration of Bluetooth 5.3 technology provides a stable and reliable connection. Multipoint pairing allows for seamless switching between multiple devices.

The sound quality is surprisingly impressive for such a small speaker. The bass response is surprisingly deep and rich without overpowering the mids and highs. I tested it with various genres of music, and it handled everything from acoustic tracks to electronic dance music with relative ease. The volume is more than sufficient for small to medium-sized gatherings. Battery life lived up to its claim of 12 hours during moderate usage. The Bluetooth connection remained stable even at distances up to 25 feet with minimal interference. There is a slight loss of volume at the upper limits. The speaker can be a little muddy at its maximum volume.

Pros:

• Compact and portable design
• Excellent sound quality for its size
• IP67 waterproof and dustproof rating
• Long battery life (approximately 12 hours)
• Stable Bluetooth 5.3 connection
• Durable construction

Cons:

• Maximum volume lacks clarity.
• Slightly pricey compared to some competitors.

The SoundLink Flex (887612-0300, 2nd Gen) is a fantastic portable Bluetooth speaker. Its exceptional sound quality, rugged build, and long battery life make it ideal for outdoor adventures and everyday use. While the price point might be a consideration for some, the overall performance and reliability justify the cost for those seeking a top-tier portable audio solution. I wholeheartedly recommend the SoundLink Flex (2nd Gen) to anyone looking for a versatile and durable speaker that delivers excellent sound.
