Now with 2 SoundLink Flex speakers, the loudness is similar with a better sound signature. Most importantly, with 2 units you get nice immersive wide stereo sound separation . This is a whole new level of added listening experience. On top of that you will not need to push the speaker to near max when you have 2 units, they can produce a pleasant sound with decent bass, mids and highs.

The Bose Soundlink Flex (2nd Gen) is a compact portable speaker that can be used inside and outside the house. It was released in late 2024, three years after the original Soundlink Flex , which was a fantastic piece of kit at the time. I’ve tried both devices – and while there’s not much difference between them, the latest model is undeniably more refined.

The Bose SoundLink Flex (2nd Gen) takes up a bit more space than most shower speakers, but it rewards you with excellent sound right out of the box. It’s IP67 rated, making it safe around water and steam. The built-in utility loop also makes it easy to hang from a shower hook or caddy.

And if you're looking at the Flex, it steps it up because it's coming with a custom transducer and it's coming with dual passive radiators on the back, front and back. So that's going to give a clearer sound and deeper bass. It comes to something like charging. This is where you'll notice the difference between the older models and the newer models. So the Micro had come out in 2020.

And for the star of the show, we got the Bose SoundLink Flex in this blue color, and this thing looks amazing. As you guys can see, this is really well built. The front speaker grill is massive. And at the back, we also have an additional speaker grill, which is good for bass. And if we take a look at the top, we have a few buttons.

No matter where you place it, flat, upright, hanging from a hook, the sound stays balanced. That's thanks to Bose's Position IQ Tech, and it actually works.

Despite its small size, it produces rich, balanced, high fidelity audio with clear vocals, detailed mids, and surprisingly deep bass. The sound is full and immersive, allowing you to enjoy music the way it was intended to be heard. Whether you're listening to pop, hip hop, rock, or podcasts, the audio remains crisp and well-defined.

The Bose SoundLink Flex (2nd gen) is a classy-looking speaker with solid enough performance to be a strong contender to the Flip 7, UE Boom 4 and others. However, it's a little larger than the Flip 7 while being not as tough and with fewer EQ options.

I was really hoping for more meaningful upgrades after the speaker since it is Gen II.

Just be aware, you are taking an added risk buying blind, and JBL 's current offerings are a tried and tested factor we recommend for a reason.

Now, the only thing I would mention though is that because this exposed grill is metal, it will mark quite easily if you drop it face down. So, it will show signs of wear and tear a little bit easier than other options on the market, which is just something to bear in mind. Okay. So, not much has changed from a design perspective then.

Maybe bose flex is better but its damn ugly - coming strait from the 80s - will choose the marshall because its elegant!

I'll say the Bose is warmer, the JBL is brighter. Uh I think both have the same amount of bass. I think in particular, just in this track I felt the JBL had a little bit more bass. Uh let me know if you all feel something different. But yeah, from me that is about it.

If you’re after deep, full sound, I’d say Bose is your pick. Otherwise, go for Marshall. Just my personal opinion.
