Review of Anker Bluetooth Transmitter/Receiver with lots of pics!!!

This is a review of Anker Bluetooth wireless Transmitter and Receiver. http://www.ianker.com/product/99ANRECV-02BA
How many times you wished to "cut" the wires and use your headphones or speakers without "strings" attached? How about listen to your laptop or TV wirelessly with an existing set of bt headphones or wireless speakers? For sure there are a lot of scenarios, but often it involves 2 separate bluetooth devices, a receiver and a transmitter. If you combine both of these functionalities into one super compact package - you get Anker BT Tx/Rx module I'm going to review next.
You never know what to expect when you see a picture on vendors website in terms of the product size. So when I received this device from Anker for review, I thought it was very small to begin with according to box size. Packaged inside of recyclable box without any hint of plastic, just like other Anker products, the actual surprise came when I opened it up to find a matchbox size device. We are talking about 2" x 1.4" x 0.3" and at 48g - this is tiny, even so it had a metal body with some touches of plastic. Along with a unit, there was also usb to micro-usb cable and 3.5mm male to male audio cable. The device is rechargeable, and supposed to last almost 12 hours in transmitter mode and 7 hours in receiver mode. Controls and ports are very minimalistic. You have micro-usb charging port, 3.5mm audio jack, a small led to indicate power/pair/status activity - on one end side of the device. You have Tx/Rx switch along the edge, and Power/multifunction button at the top. That's it.
Operation is very simple. You flip the switch to Rx (receive), and plug your headphones in. Press and hold multi-function button until blue led starts to flash continuously, and go to your smartphone or tablet to scan for available devices. Select and done! For Tx (transmit) mode, flip the switch to Tx, connect Anker device through 3.5mm cable to your source (I had it connected to my ThinkPad laptop), put your wireless device (I was using wireless speaker) in pairing mode, hold multi-function button down on Anker device and it will get paired up automatically. Anker included very detailed instructions so there is no guessing. Typically different blue led flashing patterns on the device will indicate when its pairing up and when its connected. If you mess up, turn power off, and start again. There is also auto shut-off mode if no devices are connected after power turned on.
I do have to note, this is Bluetooth 2.1 with support of A2DP and AVRCP protocols. As a result you will have a reduced sound quality, not significantly but for sure your audiophile quality headphones will not sound the same as connected wired. I was able to test wireless range to be within 30-33 feet as mentioned by the spec. Another thing to keep in mind, if you wired headphones have in-line remote/mic - it will not work connected through this wireless bluetooth device where only audio going to come through.
Overall, I actually found this device to be very useful and convenient where it combines 2 separate devices into one attractive small package. Factor in 18 months warranty and support you get from Anker - this is one great value for under $30.
Here are the pictures.

YCCTEAM 34 inch Wireless Soundbar

This soundbar is great. Originally i had planned to use this in my kitchen to complement a small tv there. When the soundbar arrived and I unboxed it I was pleasantly surprised by how much volume I got out of the thing when playing music from phone via bluetooth. There was zero distortion. I've had cheaper units before where pieces felt like they could fall off right out of the box but I can tell you this is NOT the case with this one. It feels solidly built. The mounting hardware it arrives with is sufficient to handle this thing with zero issues.
At this point in time I have changed my plans for this soundbar and will be using it on my screened in back porch. I have one of those LED TVs that has the small tinny speakers. Not a problem anymore! I've tested using my Nexus Player to broadcast audio via bluetooth to the soundbar without a hitch. Even works great playing live TV in KODI using my HDHomeRun (see video). In fact, it so loud and so clear that not only will this cover my porch but will cover my pool with clear sound as well .
YCCTEAM does seem to be one of the companies out there who listen to what consumers want. The original version of this soundbar did not come with optical or coaxial digital inputs. They have now added these two inputs for the 2016 model which only adds more value for the money.

[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,
