Bose - SoundLink Flex (2nd Gen)

Why only 3 options? I'm a fan of the bose flex 2 currently. Its very portable, its durable, has good bass, gets loud and you can link two of them to run in stereo which sounds way better and louder than a single speaker.

Uboom X, it now on sale for only 92 dolar. Its a great speaker. Especially for this price. If you like deep bass, good mids and highs this is a great pick. Fast charging trough ucb c. Powerbank for your phone. Great eq possibilities. Loud sound with deep bass. Ip67. Pair it till 50 speakers. Aux in. The bose soundlink flex 2 is a great speaker. Portable, good deep sound. It will sound a lot bigger than it is. Ip67. Usb c charging. Great build quality. 3 band eq trough the bose app. Durable rock solid design. Fantastic color options.

Bose soundlink flex 2 has great bass for on the go. Especially for it's size. If you play with the eq in the bose app and put it in the corner. It sounds way bigger that it's size. Earfun Uboom X is also great. Its larger but almost the same price as the bose. The bass on it is fantastic. Devialet Mania is an wonderful sounding speaker. Big bass, great highs, and a big price haha 😉 Jbl flip 7 or charge 6 are great for outdoor usage.

I love my bose SoundLink flex 2

Bose Soundlink Max... I have the little Soundlink Flex 2 and it already sounds serious for its size... I can't imagine the Max...

Xiaomi Sound Pocket is a bit amazing (for my scooter 🛴) Bose SoundLink Flex 2 also, for a small house 🏠 I'm happy with both, excellent sound 🙀🤗👍

Very happy with the UE Boom 2 for 10 years but replaced by the Bose SoundLink Flex 2 which delivers very pleasant sound (if you lower the bass a notch with the 3-band equalizer) and a small Xiaomi Sound Pocket 5w for less than €20, very satisfactory for my electric scooter 🛴

I find it hard to say bad things about one or the other. I've always liked the neutrality, spaciousness and lack of distortion of the UE Boom 2. The Bose SoundLink Flex is characterized by a very rich sound, including the bass (which in my opinion should be lowered a notch in the equalizer as already mentioned in a previous comment). Still, listening to Pink Floyd's "The Wall" on it for example is pure joy, even at high volume...It almost feels like you have hi-fi speakers in the room, it's very impressive compared to the size of the speaker. Its main fault is its very weak autonomy, we end up using it almost always plugged in but what a sound! Very pleasant (but the EU was far from unpleasant but only more neutral, therefore less flattering) That's basically my opinion 🤗

The Chinese speaker has strong bass, but it becomes annoying over long listening sessions. Overall, the JBL Flip 6 is worth a try. If I were to recommend one, go for the Bose Flex 2 – its bass sounds more authentic.

Bro motion 300 doesn't come close to Flip 6 in the terms of clarity, instrument separation and bass, but still jbl is a little bit harsh. My first Bluetooth speaker was tribit stormbox micro 2, a bit smaller than average portable speakers and I love it's sound profile it was best to my ears. Later on I tried tribit sound plus, JBL flip 6, motion 300, and currently I'm having Bose SoundLink flex Gen 2. Bose is not everyone it doesn't have a bright sound. And the soundstage is narrow but still somehow it's favorite to Many. I didn't try tribit stormbox flow but I heard it has same sound profile as tribit stormbox micro 2. Tribit sound plus is also called audiophile level speaker so you can try sound plus 2. Motion 300 bass some time so bad that unbearable.

Bose soundlink Flex 2 or the Marshall Emberton 2 I guess! Amazing sound, and experience!

The box flex is the model I’ve been eyeing hard. I really like the Bose tuning and own a pair of QC. If and when the UE kick the bucket, I’ll probably the flex 💪  How would you describe the sound profile between the boom 2 and flex 2 ? 

Newer version actually does sound better. It has better midrange and treble. Plus you the new one has EQ

If you would trust the frequency response graph so much, what about the +6dB crest at 150Hz and -6dB troughs at 100 and 80Hz, and the bass roll-off below 62Hz? I'm measuring from the brighter sloped blue line btw, to minimize the deltas, but +-6dB is a huge range, and that's before you accommodate the THD+N. +3dB is double the loudness, +6dB is quadruple, and all these are very sudden changes thus quite perceivable to the human ear. This is definitely not THE best Bluetooth speaker by any stretch of the imagination.

You never specify a size, you only say Bluetooth speaker. Along these lines, JBL Boombox 3 should be in the comparison, and if you really mean THE BEST, an actual HiFi system that coincidentally has Bluetooth support is definitely better than the SoundLink Flex. Also, you seemed to be disregarding the role DSP plays in modern portable speakers. I've been making a few DIY speakers myself with the BP1048B2 DSP chip and it's ACP Workbench tool, and when you get this kind of control over signal processing, you can nearly compensate for all peaks and troughs on the frequency response graph digitally, but you can't make the drivers perform better on transient response or improve directionality performance for a specific use case. That's some of what's missing from you claiming about how good these speakers are by just referring to a frequency response graph. Again, I understand that you really like their performance from 500Hz and above, and I don't disagree with you, but we don't buy a portable Bluetooth speaker to use it just as the satellite speakers of a 2.1 system, not that you can do that with Bose anyway.
