[Review] Syllable D700 Bluetooth headphones for 20$

Hey,
some days ago Syllable sent me a pair of their D700 bluetooth in-ear headphones for review so here it is now
Let me first clarify that I am neither paid by them nor related to them in any other way.
Let's start :highfive:
General information​
The headphones ship in a small box with them printed onto it:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
After opening it up one can see the headphones, a charging connector that is rather short but long enough if you ask me and ear plugs in different sizes:
The medium ear plugs are already attached to the speakers, a smaller and a bigger pair ships with them. I had to go for the smaller onces as my ears are quite small. This was definitely a big plus for me!
The headphones have three buttons as you can see here:
The key mapping is
Volume+/Next Song
Pause/Shutdown or switch on
Volume-/Previous Song
The first element in the list corresponds to a short press whereas the second element is a long press.
The buttons have a good haptic feedback in my point of view! There is also a microphone built in which really surprised me keeping in mind that these things cost just 20$! If you receive a call while wearing them a single press on the middle button answers it. If you then press again the call is hung it.
I collected the following results while running a 15km run:
Pairing​I used an Elephone Trunk and an Elephone P8000 as a pairing device and both worked fine with the headphones. To pair you simply have to press and hold the middle button until the speakers turn themselves on. A built in LED then starts to blink blue and the "D700" can be found in your BT smartphone menu. Only one device can be paired at a time so if you switch devices, you have to turn off bluetooth on the first device in order to pair the second one. I think that's reasonable as also only one person can listen to the music coming out of these headphones so there is no need to pair more than one device at a time.
Sound Quality​The sound quality is okay for me. I usually wear on ear headphones which have a lot of bass - obviously the D700 have less bass and more mids and highs. When I pushed a bit onto the earphones the bass became more present but that is nothing I want to do while running. I still like the sound quality given the low price and the fact that these things have tiny speakers compared to my big headphones. These highs help to understand a calling partner though if making a call. Also I have to note that the built in microphone seems to be good as well because my partner did not have any problems understanding me.
Battery Life​The D700 came pre-charged and without further ado I literally hit the ground running and tested them. Surprisingly the battery lasted the whole 1.5 hours run! The box states 5 hours music time and I ran another two 1.5 hour runs after charging the device's battery via micro USB, so I'd say that's more than enough if you go running. If you want to use these things for daily music I am pretty sure that you won't make it through the whole day if you listen to music all the time. But I wouldn't recommend that anyways because of the...
Design​The design of the D700 is not exactly subtle. My pair came in a neon yellow color and I am pretty sure the designers aimed rather at runners than at businessmen. The headphones are not exactly ugly but I personally would not wear them other than for running or sports in general.
Conclusion​After all I am rather impressed by these inexpensive headphones! You basically get a full functional bluetooth headphone pair with built in microphone, calling feature, music adjustment buttons and a decent battery life for just 20$! Also the bluetooth range is really great! After running I walked into a different room while having my phone lying on the desk and there were no connection problems at all.
The only downside I can on the D700 spot is the extroverted color.
Pro:
Cheap - 20$!
Good sound quality!
Good battery life!
Calling feature!
Great BT range!
Comes with three pairs of earplugs!
Good fit!
Con:
Color
If you're looking for a cheap pair of wireless headphones for doings sports, go for these guys! You won't be disappointed. :highfive:

[Review] Syllable D900s cableless Bluetooth headphones

Hey,
some days ago Syllable sent me a pair of their D900s bluetooth in-ear headphones for review so here it is now
Let me clarify that I am neither paid by them nor related to them in any other way.
So let's start :highfive:
General information​
The headphones ship in a box:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
On the backside there is a lot of information printed onto it:
After opening the box you can see the headphones, which sit in another small box:
Going further along the unpacking, you get several goodies:
a micro usb charging cable
earplugs in different sizes
a band which you can use to hold the headphones together (I like the idea a lot!)
Here are the headphones unpacked:
Each of them has a button and clicking it will pause the music or end the current call. Pressing twice will call the last person you called. Unfortunately there is no way to skip tracks like it was possible on the D700.
Review:
Pairing​I used an Elephone P8000 as a pairing device and it worked fine with the headphones. To pair you have to press and hold the button on the right headphone until it starts to blink. Then "SYLLABLE TIP" can be found in your BT smartphone menu. Once it is paired you can switch on the left headphone and they will automatically pair. The next time you want to use them just hold and press the button for a short time and your phone will pair with them automatically because it already knows them. So basically you have two modes:
discovery mode (long press on startup) which lets you pair new devices
normal mode (short press on startup) which lets you pair devices already known to the speakers
Note: Only one device can be paired at a time so if you switch devices, you have to turn off bluetooth on the first device in order to pair the second one. I think that's reasonable as also only one person can listen to the music coming out of these headphones so there is no need to pair more than one device at a time.
Sound Quality​The sound quality is surprisingly good for the size! I usually wear on-ear headphones which have a lot of bass - obviously the D900s cannot compete with these. They have more highs and mids. When I pushed a bit onto the earphones the bass became more present but that is nothing I want to do while running. I still like the sound quality given these things have tiny speakers compared to my big headphones.
Calling​I made some test calls while in a silent room and my partner could hardly understand me. That is now big surprise to me though because the microphone is basically in your ear. If you call people a lot via BT, go for different headphones.
Battery Life​The D900s came pre-charged but I charged them nevertheless. The battery lasts surprisingly long (nearly 4 hours!). If you want to use these things for daily music I am pretty sure that you won't make it through the whole day if you listen to music all the time. But that is still not a problem, because the tiny plastic box in which the speakers can rest has a dedicated battery built in. Here you can see how they are charged:
. Once they are full you have 4 blue LEDs in the box which indicates the external battery capacity. So even if you are on the go you can charge them by simply putting them in the box!
Design​The design of the D900s is subtle but it still looks a bit odd to have these things in your ear My pair came in decent black so you won't notice them immediately. I will still wear them in my daily life I guess.
Conclusion​After all I am rather impressed by these headphones! You basically get a full functional bluetooth headphone pair with built in microphone, calling feature, and a decent battery life! And they are really tiny! Also the bluetooth range is really great! The only downside I can on the D900s spot is the low bass.
Pro:
Tiny!
Good battery life!
External battery!
Calling feature!
Great BT range!
Comes with two pairs of earplugs!
Good fit!
Con:
Little bass
Call partners will hardly understand you.
If you're looking for a pair of wireless headphones and you want them to be as tiny as possible, go for these guys! :highfive:

[Review] Syllable D300 Bluetooth headphones for 12$!

Hey,
some days ago Syllable sent me a pair of their D300 bluetooth in-ear headphones for review so here it is now
Let me first clarify that I am neither paid by them nor related to them in any other way.
Let's start :highfive:
General information​
The headphones ship in a small box with a long charging connector and ear plugs in different sizes:

}
The medium ear plugs are already attached to the speakers, a smaller and a bigger pair ships with them (bigger is not in picture). I really like the little clamp that comes with them so I can attach them to my shirt. Big plus!
The headphones have three buttons as you can see here:
The key mapping is
Volume+/Next Song
Shutdown or switch on/Pause
Volume-/Previous Song
The first element in the list corresponds to a long press whereas the second element is a normal/short press. This is quite counterintuitive given that the buttons have + and - printed on itself. Once you figure that out it is easy to use though The buttons are also a bit sluggish to press but they are still usable. There is also a microphone built in which really surprised me keeping in mind that these things cost just 12$! The call quality is mediocre though. If you receive a call while wearing them a single press on the middle button answers it. If you then press again the call is hung it.
Pairing​I used a Blackview Alife P1 Pro and an Elephone P8000 as a pairing device and both worked fine with the headphones. To pair you simply have to press and hold the middle button until the speakers turn themselves on. Then keep holding the button until the built in LED starts to alter between blue and red. The "D300" can then be found in your BT smartphone menu. Only one device can be paired at a time so if you switch devices, you have to turn off bluetooth on the first device in order to pair the second one. I think that's reasonable as also only one person can listen to the music coming out of these headphones so there is no need to pair more than one device at a time. If you wanna use it after pairing again a short power button press is sufficient so you don't have to hold the button longer than 1 second when starting the phones the next time.
Sound Quality​The sound quality is good! I usually wear on ear headphones which have a lot of bass - obviously the D300 have less bass and more mids and highs. When I pushed a bit onto the earphones the bass became more present but that is nothing I want to do while running. I still like the sound quality given the low price and the fact that these things have tiny speakers compared to my big headphones. They also have better bass compared to D700 which I reviewed here.
Battery Life​The D300 came pre-charged and I tested them immediately. The box states 4 hours music time which is a realistic value. After charging the device's battery via micro USB, you get 3.5-4 hours out of them.
Design​The design of the D300 is rather extroverted. My pair came in a neon blue color and I am pretty sure the designers aimed rather at runners than at businessmen. The headphones are not ugly but I personally would not wear them other than for sports or when being at home.
Conclusion​After all I am rather impressed by these inexpensive headphones! You basically get a full functional bluetooth headphone pair with built in microphone, calling feature, music adjustment buttons and a decent battery life for just 12$! Also the bluetooth range is good! The only downside I can on the D300 spot is the extreme color.
Pro:
Cheap - 12$!
Good sound quality!
Decent battery life!
Calling feature!
Great BT range!
Comes with three pairs of earplugs!
Good fit!
Con:
Color
If you're looking for a cheap pair of wireless headphones for doings sports, go for these guys! You won't be disappointed. :highfive: I definitely recommend to buy them because of the low price and good features! I would also prefer them over the D700 but that is my personal opinion.

Unboxing
First of all, ignore the package's conditions since, well, this is how i got the package from the courier. Luckily everything was fine inside. Anyway, just like the previous A320 i reviewed last year, this one comes with the same amount of accessories: 1x Micro-USB Cable, 1x 3.5mm Audio Cable, 1x Kit of Rubber Pads, 1x Protective Pouch and the Speaker (of course).
Also as regards the design and materials, everything looks exactly the same, with a nice bamboo-style front, some sort of fabric all around the device. Everything is well-made, with no imperfections (even better than the A320) and a great attention to details.
The whole back side features the same bamboo-style look with an air output (for the Subwoofer) on the bottom and the I/O Zone in the middle.
In the I/O Zone, completely rubberized so a bit easy to scratch, there is an AUX/Audio Input 3.5mm connector (just like a standard headphone jack) required to use the device in wired mode, a Reset Button, a Red LED that turns on while the built-in battery is charging and a Micro-USB port (for charging).
On the lower side instead there isn't anything at all, with just a sticker (that can be removed) with some data about the device.
As regards the Speakers, just like on the A320, there is a Subwoofer in the center and one speaker/tweeters for each side. It is said that, compared to the predecessor, the quality has been improved slightly. Is it true? Well, follow my next paragraph to know more.
On the upper side instead there are all Keys (Volume Up/Down, Play/Pause, Power), and an Activity/Connection LED with a Microphone just below.
Sound Quality
Compared to the A320, what Archeer says is slightly true, i notice an higher amount of high frequencies while keeping low frequencies reasonably high. But, it doesn't mean that it is perfect since it isn't at all. This is still a speaker made for bass-lovers, with the most punchy sound you can probably get from a bluetooth speaker and terribly high sound pressure.
Of course this means that there is a lot of output power there, and this is true, as you can see from this photo taken while running my classical Dolby Sound test.
Still, i would have preferred to get a switchable equalizer in order to switch from a full-bass to a more balanced mode in order to satisfy all kinds of users.
But, the main reason why i choose to get this new A320S model instead of keeping my old A320 is the TWS (True Wireless Stereo) mode, with the possibility to pair to speakers together in order to get the best sound experiece. Does it work properly? Yes, super-fast to configure and, together, the output power gets even higher. Technically, you get 25W x 2, with a total of 50W! My sound meter isn't even able to record the difference, but some decibels extra are here.
Controls and Connectivity
Unlike the A320, on this model there seems to be a Microphone, and my smartphone confirms it since Phone Calls are supported too. This is an huge improvement even though the result is not the best, but still better than nothing.
Unfortunately there is no Bluetooth Version upgrade or APT-X support addition with this new model, thus it still works on Bluetooth V4.0. It isn't bad, but you will never be able to get the same audio quality you can get using the wired connection instead.
Let's say that an small Bluetooth Version upgrade plus the addition of an Optical Audio Input would have made this device almost perfect.
Conclusions
After many days of testing, i might say that this isn't a product for everyone and, most important, if you already have the A320 model and don't need, or can't afford, to get two A320s for the Stereo Feature, then it would be useless to get it.
I am partially happy of this new model, and i say partially because i would have expected an higher amount of upgrades, especially considering that this is still a pretty expensive piece of technology.
This is a product, or better a niche product, that i can recommend to those audiophiles with super-high bass "in the blood", but for those who prefer a more clear and high-pitched sound that can't use an equalizer to reduce the amount of low frequencies, then this might not be the right product.
Pros:
- Built-in Microphone
- Good Battery Life
- Outstanding Power Output
- Supported Dual Speaker pairing (TWS)
Cons:
- High frequencies are still limited
- No Optical Input
- Outdated Bluetooth Version with no APT-X support
Rating: 8.7
Packaging and Accessories: 9.5
Design and Materials: 10
Sound Quality: 9.1
Connectivity: 7
Price: 8 (based on Amazon price)

[Review] UGREEN Bluetooth 4.1 Audio Receiver

So I've just received a Bluetooth adapter from UGREEN for review purposes. No strings attached no nothing - 'just write something about it' kind of a deal - which I dig.
Being a huge nerd has its perks. I enjoy surrounding myself with tech that makes my everyday life a bit more enjoyable.
For bluetooth streaming, my everyday driver are the MDR-100ABN h.ear on headphones from Sony.
Once I go running or at the gym or in any environment that involves faster-than-walking pace, I switch to my all time darling, the Elecom LBT-PAR500 receiver which securely stays attached on clothes.

So where does the UGREEN Bluetooth Audio Receiver fit in?​Well that's easy - It's made to nicely sit on your desk or in your car and hook on to your sound system or dashboard. It's designed that way.​
The nicest feature it has is the user experience. The reason I'm not using my sound system with my bluetooth receiver is because it's a hassle to plug it in, turn it on first and so on.
The UGREEN receiver turns on the moment it's plugged into an USB port - but not due to the lack of battery - it has one which lasts around 7 hours of playback - 8 advertised and the playback time also depends on the output volume, used codec, etc. I find this extremely useful while sitting hooked in the car. As soon as you turn the key, it will flash it's light and be ready for paring/connecting.
Design wise, it's bulky yet modern - nothing too fancy. One big button on top, a light, and the I/O in the back. It has no microphone tho - so no calls can be made/received on it - it does not utilize hands-free profiles so an incoming/outgoing call will be heard only the phone. It's probably for the best since I personally can't stand loudspeaker calls.
Again, it's a device that should be plugged in and forgotten. The auto-pairing mode once on and the auto-power on when fed to a powered usb port makes it excellent for a car. Once you disconnect from it, it automatically powers off after 5 minutes of inactivity. Personally I like to have it hooked to the sound system with power supplied from the PC - so when I turn on the PC, it'll automatically be ready.
The audio quality and transmission range are as good as you'd expect them to be in 2018 so there isn't any obvious difference. The advertised bluetooth class is 4.1 with EDR (enhanced data rate) should have a transfer rate of 24 Mbps or higher - wish I knew the available bluetooth codecs. It uses AVRCP and A2DP profiles. But it's 2018 - most of the bluetooth adapters sound pretty CD/Studio quality like.
As my impressions have been presented, I'll be switching to a Pro / Con list as it follows.
PROs:
Great price/value ratio - 16$ on Amazon;
Solid build quality - there's also a rubber ring on the back to keep it from slipping;
Easy to pair and connect - great for car installments;
Long battery life and one button for ease of use;
Whilst it is no amplifier, it's louder than the average phone 3.5 jack output;
RCA and 3.5mm connectivity is a plus - they can be used simultaneously;
Lightweight and portable - if need arises.
CONs
It's a bit too light - hence the rubber ring on the bottom;
The package usb micro-usb arresting hooks are a bit too tightly clawed in the device - exercise care when removing the cable - not really a con, more of a caution;
I wish the status light was on the button ring instead of on the side of the device;
Lack of loudspeaker capabilities - I don't need it but it's nice to have;
Lack of player controls.
To conclude, it's a great device for its price. Perfect for a car or for adding bluetooth connectivity to home sound systems. As I said in the beginning - it makes connected life a bit easier.
I'd like to thank UGREEN for this device :silly:. You can find more about them and their products on https://www.ugreen.com/ and you can learn more about the device here or see their listing on Amazon here
Have a good one,
Sebastian

Hi Sebastian,
I was feeling curious if I could change some config settings of this bluetooth device. I read that Ugreen 3044 works using a CSR chip from Qualcomm, so can be "easily" configured via an UART connection to the chip. The reconfiguration work is undergoing, so until I will get some results I will post here my updates.
Anyway, if you want to open the case, I wish you good luck, because I partially broken some small tightening "things", I think they made this either unbreakable or unrepairable. Here are some photos from inside the box, featuring the CSR8635 chip.
Stefan,
