Bose SoundLink Flex (2nd Gen) Review: Rugged, Loud & Worth It?















If you’re on the hunt for a compact yet powerful portable speaker, the Bose SoundLink Flex (2nd Gen) might just be the audio companion you’ve been waiting for. Known for their industry-leading sound engineering, Bose has refined its portable offering with impressive durability, sound performance, and smart features—perfect for those who want to bring bold sound on every adventure. But is it the right speaker for your lifestyle? Let’s break it down.

Bose SoundLink Flex (2nd Gen) Speaker Features

Hi-Fi Sound with Deep Bass in a Compact Body

Don’t be fooled by its size—the SoundLink Flex (2nd Gen) delivers high-fidelity audio with deep, room-filling bass that’s bold and clear. The speaker uses Bose’s proprietary technology to produce a balanced sound profile, delivering crisp vocals and punchy lows even when used outdoors. Whether it’s your playlist at the beach or a podcast at home, the audio experience remains immersive and rich.

Durable and Adventure-Ready Design

Built for real life, the speaker has been rigorously tested to meet an IP67 rating, making it both waterproof and dustproof. Wrapped in a silicone-coated body, the SoundLink Flex can handle drops, shocks, rust, and even crushing pressure, making it ideal for travel, hikes, or beach parties. It’s small enough to fit in your hand, and the nylon utility loop lets you clip it to your bag with ease.

Up to 12 Hours of Battery Life

With a 3200mAh battery, this speaker offers up to 12 hours of playtime on a single charge. That’s more than enough for a full day of music without having to stop and recharge. The speaker takes about 4 hours to fully charge, giving you more time to focus on fun rather than power management.

PositionIQ Technology for Optimized Sound

Wherever and however you place the SoundLink Flex—standing, lying flat, or hanging upside down—Bose’s PositionIQ technology detects its orientation and automatically adjusts the audio output to deliver the best possible sound for that position.

Advanced Bluetooth 5.3 with Multipoint Connectivity

Connectivity is strong and seamless thanks to Bluetooth 5.3, offering stable playback from up to 30 feet away. You can even pair multiple devices simultaneously and switch between them without re-pairing, thanks to multipoint connectivity.

Party and Stereo Modes for Bigger Sound

For those who want even more sound, the speaker supports Party Mode and Stereo Mode when linked with another compatible Bose speaker. Use Stereo Mode for true left/right channel separation or Party Mode to fill a larger space with sound.

Smart App Integration

Using the Bose app, you can adjust the EQ, manage connected devices, monitor battery life, and even customize shortcuts. This brings more control to your fingertips for a personalized experience.
