YMOO DAC Bluetooth 5.1 Receiver,LDAC Aptx 30ms Low Latency,Optical Coax RCA 3.5mm Jack Hi-Res Input, Lossless Wireless Audio Adapter for Subwoofer,Soundbar,Speaker from Phone/Tablet/PC/TV,96Khz/24bit

This nifty little BT receiver/transmitter is perfect and it's small enough to setup just about anywhere! Another huge selling point for me is that is also has a built in DAC along with aptX-HD and aptX-LL (low latency), which allows for up to 96kHz/24-bit transmission over BT which is incredible and everything that I've ever listened to with it, sounds incredible and full, absolutely Zero tinny, computer artifacts that sound metallic and like a cheesy robot from an old B/W Flash Gordon serial! Great BT device, highly recommended!

Good quality!!!

This unit was a huge disappointment. The plan was to transmit the music to my home stereo receiver. The unit does not come with the plug-in adaptor, and there is no USB port on or around my receiver, so no way to power this up without buying an adaptor for it. At this price point, it should have been a no-brainer for the manufacturer to include that with the device.I just ordered an adaptor, so after it comes in, I’ll come back and update this. Maybe I’ll be in a better mood by then.

The YMOO DS221 HiFi LDAC Bluetooth Audio Receiver is a great way of connecting your phone (or any Bluetooth source) to a pair of powered studio monitor speakers. I have a pair of PreSonus Eris E3.5 studio monitors (https://www.amazon.com/PreSonus-Eris-E3-5-Professional-Multimedia/dp/B075QVMBT9) with the Eris 8 Subwoofer (https://www.amazon.com/PreSonus-Eris-E3-5-Professional-Multimedia/dp/B08MJ1CCMF?th=1) and I wanted a way of streaming music from my phone. I had been keeping an eye out for one that could handle the Hi-Res and Lossless codecs while looking good with the studio monitors.The shape (rounded and not boxy looking) and size work great for my use. Even though I knew it was small, I was surprised how small it really is (that is not a bad thing at all)! It looks great and the housing is all metal with a sharp OLED screen. The sound is amazing especially when paired with the PreSonus studio monitors/Sub and a Hi-Res source (Amazon Music). It has a built in 7 mode EQ for those who like to tweak the sound, or you can leave it flat for those of us who want to hear it the way it was recorded (hence my using studio monitors that do not color or modify the sound).Depending on what use you are planning on, there is only one con that I have found so far, and it may not matter to some or most people. You can connect via Bluetooth, or you can hook it up to a computer through the USB-C connection, but you cannot do both. If you connect it to a computer, it disables the ability to connect via Bluetooth, you have to disconnect the USB-C cable in order to use Bluetooth. Like I said, it may not matter if you only plan on connecting to it one way or the other. If you are looking to be able to switch between a computer and Bluetooth connection easily, you may want to look elsewhere.If you are looking for a way to stream Hi-Res music via Bluetooth to an older, non-smart receiver or a set of powered studio monitors or speakers, the YMOO DS221 HiFi LDAC Bluetooth Audio Receiver is a great way of doing so! I highly recommend it!

This review is for the YMOO DS221 HiFi Bluetooth Receiver. This device effortlessly adds high-fidelity Bluetooth audio support to powered speakers, stereo or A/V receivers, or basically anything with a line-in input. The stand-out feature of the YMOO DS221 is its use of relatively high-end hardware and support for updated Bluetooth codecs that work together to deliver higher fidelity Bluetooth audio compared to more conventional implementations. The common denominator for essentially all Bluetooth audio products is the SBC codec, but due partly to its flexibility and open-standard nature, manufacturers don't necessarily implement all of SBC's capabilities, thus sometimes unfairly giving Bluetooth a bad reputation for having poor audio quality.The YMOO DS221 HiFi Bluetooth Receiver addresses this problem by supporting AAC, aptX, aptX HD, and aptX Adaptive codecs that enable higher-bitrate playback with less compression versus SBC, and its "Hi-Res Audio" credentials come from support for LDAC which enables up to 96kHz/24-bit playback. The catch, of course, is that support for these improved codecs requires compatible hardware and software, so you should pay attention to what your Bluetooth audio source's capabilities are if you want to take full advantage of this product. Unfortunately, this isn't always a straight-forward process, but this is more of an ecosystem problem.The aptX family of codecs offer a good combination of sound quality and reliable connection, but since it belongs to Qualcomm, it's mainly supported by Android and Windows 10. Apple devices including phones and computers use AAC if it's available and will otherwise fall back to SBC. LDAC was originally a proprietary Sony codec that's since found its way into Android (version 8+), and it offers the highest quality and bitrates but it's also more prone to connection issues. My Samsung Galaxy S21 Ultra defaults to aptX but there's a toggle to enable LDAC in the Bluetooth menu for 96kHz/24-bit operation.Overall, the YMOO DS221 is a awesome product that comes with a very impressive bundle of audio cables including TOS Link, RCA to RCA, and RCA to 3.5mm. It also comes with a USB-A to barrel connector for 5V power input, and a USB-A to USB-C cable for use as a USB DAC. The USB DAC mode isn't particularly impressive since it's limited to 48kHz/16-bit and thus isn't considered "Hi-Res Audio", but it at least the ESS DAC is better than what's used by most computers and phones for their headphone out.Notes:1) The DS221 needs the USB to 5V power connection in both Bluetooth and USB DAC mode. Power consumption is very modest (<1 watt) and basically any USB power source should work.2) It features the Qualcomm QCC5125 Bluetooth SoC and ESS Sabre 32 ES9018K2M DAC3) The spectrum bars in the lower right corner of the built-in display are just for decoration. It's just a repeated pattern.

I bought a stereo when I was stationed in Europe many many years ago and I still love listening to it…but now with this device I am able to stream music from my iPhone! The sound clarity is nearly on par with high end CDs and it connects with my iPhone as soon as I am in range, you can use the device for volume control as well, but I just use the iPhone’s volume.

Super cool addition to my home stereo that's a bit older I've got the new school Bluetooth setup as well with my phone and laptop Etc but with the old receiver and my record player now I've got Bluetooth High Fidelity capabilities it's got a decent reach like only into the other room but it's still pretty good to have the options and the sound quality is better than average there is a definite difference between with it and without it.
