The long screws are used as pillars. Support beams to help in rigidity.

Usually things lose their IP rating after you open them up. It's nice to be able to see a video of it instead of having to open my own.

[@dannylewandowski2822]

For its size, sound quality, and price: this has to be the best speaker on the market right now. Great job Bose.

[@petervdveenmuis]

I do agree.

[@joelf5565]

I’ve owned for a long time a large Paradigm sound system and I do agree. This speaker sounds quite amazing in sound quality.

[@Sergei__v]

it is very impressive engineering by Bose. To make a mono speaker sound so pleasing is quite challenging. They made a magical speaker with this one.

[@xirtus]

yes but perhaps they could have used a much smaller footprint looking inside I see ways this could have been slightly larger than the speaker and not much more.

[@Sergei__v]

@@xirtus I am sure the size of the driver and cabinet are matched to get the tuning right.

[@nickjonas3704]

Trust me, this is the bang for buck 🤑

[@joelf5565]

Indeed. I’ve compared to other similar sized BT speakers that are supposed to be stereo and they don’t sound as good as this one. I also have a second Flex and do stereo pairing. When I go back to just the one speaker it still sounds quite nice and spacious.

[@alexmanojlovic768]

​@@Sergei__vthat's where Bose excel. Tiny speakers, perfectly tuned to get a sound frequency/volume level closely matched to much larger enclosures. Not always the best sound, but for compact speakers in (cheap) plastic bodyshells, which they sadly, then charge a lot of $$$ for. I auditioned a surround sound system with 3" cube satellites & the soundspace was unbelievable for tiny boxes, little larger than engagement ring boxes. Almost invisible. But oh boy the $$$ I passed...

[@djijspeakerguy4628]

One of my favorite things to do with these little Bluetooth speakers: set the driver on the table upside down and see how much it jumps around. Unlike a large driver, the lightweight and powerful neodymium magnet on these seems to actually provide some thrust! They’re also extremely overbuilt drivers that are quite hard to damage this way. I remember doing this on my original 1st generation JBL charge back in the day and laughing. This seems engineered way better than that one was. Same with the modern JBL Charge 5. Both are way better than most speakers were back then. Honestly with the Flex, Bose is finally back to the standards they set with the original Bose Soundlink mini. Flex really is the only Bose product that’s worth the price IMO. Really makes you realize how far ahead of its time the original mini from a decade ago was.

[@troykm]

At 7:18 you can clearly make out the model number TPA313602 this is a Texas Instruments digital amplifier. Wouldn't surprise me if the dac was TI too. Can't quite see the numbers on it.

[@rm25088]

i love this thing. I only got it last night but I am absolutely stunned by how good it sounds.The cool thing is is that bose is located a couple towns over from me. So maybe my speaker was made there. That Bosch screwdriver is pretty cool.

[@rm25088]

@@ITCHYtriggafinga0 Nah massachusetts. Maybe thats just offices.

[@ronch550]

Those screws are so long because the case is plastic. All the vibrations will eventually wear out the plastic that holds the speaker in place, and the screws help make sure it'll be a long time before things start resonating.

[@djijspeakerguy4628]

More likely for waterproofing, but I agree. The screws holding the driver into the box are actually 4 of 10 screws holding the entire front of the box onto the speaker. Some would say it’s overbuilt (JBL doesn’t do this) but I actually think it’s a sign that they want their speaker to last a while and hold up to heavy use including outdoors. JBL gets around this by using rounded boxes instead, and I do think their product is well built too. I’ve not handled the new Beats Pill or Sony ULT Field 1 in real life yet, but it would be interesting to see how well built they are. Not fond of Beats’ continued use of thin metal grills: they are a thing of the past, from the time of JBL’s Flip/Charge 1 and 2, both generations of Bose Soundlink Mini, the Sony SRS-X2/3/XB2/3/XB20/30/40, and other era specific speakers like the Jambox. At that Time, UE pioneered the fabric design most companies use today. Beats should either be using the woven fabric that JBL, Sony, UE use, or the durable thick metal grills of the current Bose stuff.

[@kevincelebrado5311]

Awesome video! Brought mine to the beach, dropped out of my hand and fell into the sand, got some sand in the holes of the grill, got most of it out, but couldn’t figure why the sand didn’t come out of the holes in the lower part of the front grill. Now I know why, the double sided glue strip holding the grill to the housing continues about 2-3 rows of holes up, and sand will definitely stick to that. Not sure if it’s worth opening it up, it’s a small eye sore, but doesn’t have any effect of the sound itself (that I know of). Thanks for the tear down video !

[@m0rthaus]

It won't affect sound quality - your speaker just took some souvenirs home from its beach trip 🏖

[@RobinRobin-kz7qw]

Leave it as it is! Furrows in a face show character!

[@rishabhchander9677]

Clarity and bass is mindblowing 🔥🔥🔥🔥

[@127Foxtrot]

Thanks for the tear-down, the rest of us would be highly reluctant to do this... 😱 Despite being mono, from everything I've researched, the Flex sounds even better than my Bose Soundlink mini 1, so Bose have done a superb job for also keeping the size, form factor and cost in a comparable range. That full range driver in the Flex must have some real engineering chops in it.

[@127Foxtrot]

Can someone answer for me - can you extend the Flex's runtime by connecting it to an external USB battery bank (ie. a typical 5,000 or 10,000mAh power pack?)

[@Audiohobbytojestto]

​@@127FoxtrotYes ofc any powerbank can easy handle IT ❤

[@nickjonas3704]

It is really impressive of Bose to make a mono speaker which as both clarity and punchy upper Bass that sounds deep. Even JBL couldn't do something like that with the Charge 4 and flip 5.

It’s funny how people share their opinions like they know something we don’t… I’m an Audiophile and in this category of Bluetooth speakers JBL makes speakers that at first impression, sound appealing to the inexperienced masses… but when you’ve been around for a while and have listened to all kinds of high quality music through high quality speaker systems… you know what to expect, even as small as this Bluetooth speaker is… it’s made by an audio electronics and research company like Bose. They know their stuff… and they know their target…

[@grindfi]

the csr chip is the bluetooth chip, the other big chip on the left seems to be the amplifier, and the chip next to the battery seems to be a charging/bms chip

[@grindfi]

interesting placement of the 2 passive radiators, i designed my newest speaker with the same concept, nice to see that im headed the right way

[@zpeter5880]

Thanks for the teardown !I was looking at this as I wanted to see how Bose managed to get that base from a pill, I suppose it is down mostly to those vibrating plates . It’s also known that Bose was passionate about acoustics from a young age and this shows it . Great job!

[@RennieAsh]

Bose has been quite decent at these little speakers and headphones for a while now. They combined their active EQ and small speaker devices from as far back as the 70's lol They also seem to hate using tweeters; it's full range drivers or paper cone tweeters. If you have a Bose product with a dome tweeter then it's a rarity lol

[@paulmayer4836]

My dropped then stopped working. Good video, now I can take it apart and try to find what may have detached. It doesn't seem to be that fragile in the inside.

[@greatvedas]

excellent tear down and very well explained. Thanks Shak.

[@shaktastik]

Thank you my friend ☺️

[@jordanyayala]

Mine started to rust on the grill. Probably because I left it for a while on the backpack after a beach trip. Keep an eye on leaving the speaker inside for long periods of time

[@dannylewandowski2822]

I love the rear opening on this speaker that has the rubber grill and slots. It’s like a ported passive radiator.

[@krispykorn3237]

I believe soldering is good choice for durability against dropping, shock, vibration. It is not regular that someone will replace those soldering parts. unless it's on professional with tools. At the end I finally understand how passive radiator works. AHA, as soon as the screw runs tight, the passive radiator works again. Impressive!

[@second2mouse]

Excellent teardown - every minute step covered in an easy to understand tutorial. However, I have no intension in tearing down my Flexes, very interesting video though. By the way, 2 of these speakers, linked in stereo sound even more awesome. Great product.

[@shaktastik]

Thank you very much ☺️ I haven't had the pleasure to pair both of them. But I can imagine the sound will be awesome. Why did you get 2 btw?

[@second2mouse]

@@shaktastik Yes, when 2 flexes are paired in stereo mode the result is a very noticeable upgrade. I used to have a pair of Soundcore Motion+ which, on paper, could be linked to perform in stereo. It worked but had a regular tendency to lose the link for about 1 second between speakers, which made them unacceptable for my intended usage. So I sold those and bought the flexes. Only bought them a few weeks ago. Not disappointed so far.

[@shaktastik]

Cool I've reviewed the motion+ too but you should get better bass with the flexes, enjoy and take care 👍

[@yujishinohara1uponatime]

Listening to the youtube via Soundlink Flex, impressive sound from an elegant design

[@josephbesra6348]

Is it worth buying buying two Bose speakers for party mode

[@JudgingKitty]

it depends how portable your setup must be. I would recommend the teufel boomster (similar price to 2x Bose flex.) minirig also has some interesting combinations, where you can buy 2 speakers and 1 subwoofer for example and have a portable system. I think the bose flex is one of the best really small bluetooth speakers! (I didn`t test 2 Bose Flex)

[@mikemeengs5720]

Long screws and soldered connections just ensure that nothing will ever come loose and vibrate. The thing is built like a tank. Something about its mono sound sounds off to me though. Sometimes, I'm not convinced I'm hearing the audio information from both combined recorded channels. People say they hear things in their music they never heard before...but if you take half of the music away, of course you'll notice what remains easier. Other than that though, I love my Flex! Very clean and thick sound! Fun video...thanks for showing us!

[@leimleim]

1:24 How much temperature would you recommend for that kind of plastic?

[@edoardofacciotto7261]

The sound quality difference when you reassembled everything was quite stunning. When playing with the passive radiator on it sounded amazing. Could you tell why it is so important?

[@tristanjacquel]

Double passive radiators work as bass reflex vent but in a small cabinet. They reproduce low frequencies main driver can not deliver with much level. Besides that, main driver is prevented from playing on passive radiators frequency range. Main driver excursion is lowered and thus its behavior is vastly improved. The only downside is delay at low end. But for such small speakers, it is not a concern.

[@dwdrum11]

When the enclosure screws were tightened along with the driver screws the whole cabinet becomes sealed. The fart noise you heard prior is air escaping (air created by the speaker movement) so once sealed the passive radiators then begin to absorb the sound pressure waves, this causes them to radiate sound (ie etc like a speaker cone).

[@liviualexandrubodirnea7860]

[@verynick]

People complaining about how simple and only one speaker it has without using it lol I bought and tested Flex, JBL Flip 6 and Sonos Roam. I returned them all except for Bose. Something about the well round full range speaker sound that others speakers are missing. At the end of the day, it is all about sounds, right? Haha

[@brettb8825]

Very interesting video. I've just ordered my first Flex and wanted to know if the battery was replaceable down the road. I like your screwdrivers.

[@juanfigueroa4305]

Abrir este altavoz es igual de complicado que abrir el Soundlink Micro? Se maltrata mucho?

[@krisskuli]

16:16 this is the moment where I start to wonder how these passive radiators work. I mean yes, the generell concept is clear. But in my understanding, front facing passive radiators swing out of phase with the speaker. They extend once the speaker retracts. So they show the opposite movement to the drivers membrane which should eliminate the impulse created by the driver. But instead, they inrease volume and sound... That doesn't add up.. Anyone who has more understanding of this and could explain what I don't see here?

[@bsbarber73]

Think of the way a port works. The back of the speaker pushes air through the port. The port amplifies the bass when balanced properly. In a closed scenario the speaker is pushing pressure in to a closed space. Add 2 radiators opposing one another and weighted properly it is just moving more air to exaggerate the low end. I don’t know if there is really any phasing per say because there is no polarity just low frequency energy be exaggerated. Just my observation.

[@krisskuli]

@@bsbarber73 Ah yea adding different masses to the chassis might do the trick. Anyways, very interesting concept

[@Roelypopper]

the system of the active driver and the passive radiator is damped by the mass of the air in the speaker and the mass of the passive radiator. This causes some 'lag' in the movement of the passive side, kind of how a mass on a spring doesnt react instantly when u pull on the end of the spring. This behaviour causes most of the important bass frequencies to become constructively added to the sound by the passive radiator, i.e. they move in and out in the SAME direction!

[@doorguru168888]

My sound link is less than a year old. Now, when you turn the volume too high. the unit shuts off. Maybe from vibration, maybe there's a bad solder joint.
