I tried the F8 "Colorful Rhythm" bone conduction Bluetooth speaker, a tiny black disc with a 24-bar RGB light ring. A normal Bluetooth speaker pushes sound through the air. This one is meant to stick to a surface, like a table or a metal sheet, and make that surface the speaker. I unbox it, go through the buttons and the USB-C charging port, cycle through the RGB light patterns, pair it with my phone and test what happens when I hold it in the air versus stick it on different surfaces. Held in my hand it sounds like a small speaker, but on a good surface (steel worked best) the sound changes a lot. There's no volume control on the speaker itself and no Bluetooth version is listed in the box. It's cheap, small and light, and I think it's a good idea.

This video features a review of the F8 Colorful Rhythm Bone Conduction Bluetooth Speaker. The reviewer explores the device's unique ability to transform various surfaces into speakers through vibration, while also testing its RGB lighting effects and overall build quality.
Oh! So if I check it out, the sound changes.
What's up guys! So they call this colorful
rhythm bone conduction bluetooth speaker.
I mean how can it be bone conduction when there is no
bone attached to it. I mean it's a bluetooth speaker
so it's not like I'm going to put it on
my hand or head. I mean usually bone conduction is used in that term.
So how is it bone conduction then?
But what they mean is that whatever surface you attach it to, it starts
conducting through it and it changes its sound or something like that.
Well, let's find out if that is true or not.
And it has RGB lights on it.
That's why it's called Rhythm I think they would use.
Yes, colourful rhythm.
That simply means RGB.
And you have some, not some, bunch of dots.
What is this? A type A to type cable.
good one for a good speaker
and what the heck are these is it double tape like a 3mm tape
so that you can paste it somewhere probably right
and there is also one already applied here so it's
nice of them to send two extra even
though they already did apply it so nice of them it's called
f8 by the way guys and let's quickly see what they have
to offer so paste what language is this
And what language is this? Where is English?
English, English, English, English, English, English.
And then someone is sending print.
I mean was this the time when right when I started
recording video someone in my home thought
that oh they have to send the
printer. Printer is in my home. Anyway we have light mode.
then you have white color switch key
so this there are two buttons here they are giving you this
mod and color this will change probably color then this is
mod we'll figure out there is another on off button
this is on off button guys this what is this
mic because it's rhythm then type c to charge
and this is what they call resonant contact surface of
Resonant horn washable reusable nano glue. So this one is
Resonant contact surface and that's it. And it's a Bluetooth speaker
which Bluetooth generation by the way it uses
If I can if they are kind enough to mention it.
Not really. Did you mention it here somewhere?
Not really. Okay
Alright, let's turn it on.
This is the on button. Bluetooth mode.
There is another mode as well
No, I think I need to turn off the lights for you guys to see it.

See, let's try changing
the pattern.
Hello, hello, hello, hello, hello.
Hey, hey. Okay,
let's change the pattern. This is color.
Let's change the color. Hello, hello, hello, hello.
Hello!
We're changing the color combination of the light.
Hello, hello, hello, hello.
Hello, see, change. Hello, hello, hello, hello,
hello, hello, hello, hello, hello, hello, hello.
I'm sorry for your ears, guys.
Due to my sound, let's change mode.
What? What? What, what, what, what, what?
What, what, what, what, what?
Hello. Now pattern changed. Hello. Hello. Hello.
Hello. Hello. I like the patterns by the way.
I don't know how the sound would be and what bone conduction even means
but the sound itself is really. Oh sorry. The pattern.
I mean they have given you plenty. Hello. Hello. Hello. Hello.
Hello. Hello. Hello. Hello. Hello. Hello. Hello. Hello. Hello.
Hello. Hello. Hello. I think they have started to circle back.
Hello. Hello. Yeah. Circle back.
Okay, that's connected. I think this is the maximum by the way,
and it's plenty actually.
There are still two studio bulbs on and this is the light.
Let me turn on those bulbs as well.
So now this light is not in pitch dark by the way.
This light is actually in the room light
and my room has a bunch of lights.
Just so you guys know.
So I think it looks really cute and there are good lights on it.
uh good brightness lights i would say
hello hello hello hello hello hello
hello hello hello hello hello hello
hello hello hello okay hello oh there
is a light one as well okay let's pair it
with the phone i got my phone and then
Let's try it.
What do I try it?
I need to pair it with my Bluetooth,
Bluetooth.
Is it this one?
Hello?
Hello?
Hello?
Is it this one?
Safely demo.
Oh, this is it.
There's that one.
After
that.
Let's connect.
Muffled sound.
How?
There is no volume control here or what?
Let's find some audio to play on it.
Okay.
Okay.
Okay.
Okay.
Okay.
Files audio.
Let's check it
out, the sound
changes, put it
down, the sound
changes and it
increases.
The vibration rhythm at the back.
This is by the way the maximum sound.
Change
the
surface,
not
sure
if it
is
good
thing
or
bad.
I just feel the vibration.
So
let's
try
it on
some
other
surface.
Before that let me show you how it charges.
It charges through this.
These LEDs actually.
I want you to start charging the knife.
Let me turn it off.
That's how it shows the charging.
It's already full so but it
will start from one two and three. Three is the full.
Let's end the video trying it on some other surface.
Let's go. One, two, three, four.
Alright.
Oh, it's completely changed.
When you're holding
without touching any
surface it feels like.
This is a useless speaker
but when you touch it to surface it becomes like this.
There is a rhythm to it.
Feel it now and now let me do it.
The depth that goes out comes back
when you touch it to a good surface.
Let's try it
with the wall.
See, feel it now. Everything goes.
Even down.
It doesn't work well on grass.
Where? On the wall?
What's on this one?
What about metal?
This is
metal
actually.
I think the song's on now if I watch.
This was
the bone
conduction
speaker
and how do
I pause
it from
there?
I can't
pause it
apparently from the device.
Let me pause it for a moment. So this was
the bone conduction speaker
and I think it's a nice idea by the way.
I like it. It's not that expensive.
It's cheap as it is, and even this light and make it worth it.
This very tiny lightweight.
So I think it's a good buy. I liked it.
Let me know about your thoughts as well. Take care. Bye.
