The Aluratek - Universal Bluetooth Audio Receiver and Transmitter is amazing ! It provides incredible flexibility in its input and output selection for audio. I have an older high end Alesis THX certified speaker system in my office that was made for use with computers. Because it's older, it presented some challenges with respect to connectivity problems with my iPad or iPhone. With this unit I can get a high-quality input signal transfer via Bluetooth and then send it to my system via a digital optical out and I get an incredible sound reproduction through the Alesis system. Wow, it's amazing and easy to hook up and like I said it sounds great !

Aluratek - Bluetooth Wireless Audio Extender – Black ---HIGHLIGHTS--- Long Range and Reliable Signal, Bluetooth 5.0 (apt x, apt x HD, apt x low latency), Easy to Operate, Capability to Connect Two Devices Simultaneously, Bluetooth Transmitter and Receiver ---DESIGN and CONTROLS--- I found using this device to be very easy to figure out. The first step is to plug it in using the included 9-foot micro USB cable. Then connect the desired audio cable (optical or 3.5 mm). There are two main modes: Transmission (TX) and Receiver (RX). Once you decide what mode you want to use, you set the selector switch to the desired mode. Illuminated lights indicate the mode, input, and signal being received. I am mostly going to be using this device in transmission mode to stream sound to my Sony WH-1000XM3 wireless headphones from an older Denon receiver that sounds great but lacks Bluetooth capability. I am using a 1/4 to 3.55 mm audio adapter and was relieved that it worked because not all devices are compatible with adapters. There is a third bypass mode that allows this device to function as an audio converter without using the Bluetooth function. Included Accessories: Optical Cable, 3.5 mm Audio Cable, 9 Foot Micro USB Charging Cable, RCA to 3.5 mm Y Cable ---USE AND PERFORMANCE--- Once I put this device and my wireless headphones in pairing mode they connected instantaneously. Once paired, they both connected immediately every subsequent time that I used them. Once connected the pairing was rock solid and reliable. Two pair a second set of headphones was as simple as pairing the first. The sound quality was not only excellent, but also completely lag free. I could not tell the difference between listening wirelessly as opposed to listening wired on my Sony Headphones. The advanced apt x codecs will really make a difference if your headphones are apt x compatible. I immediately noticed the impressive signal strength and range of this Bluetooth transmitter. It is advertised as up 100 feet, and very impressively I had no problem receiving a signal anywhere in my two-story house. I am not going to use the Receiver mode at this time, but appreciate that it has the capability. ---BOTTOM LINE--- Get this device if you want the very best Bluetooth performance that is out there. Yes it is expensive, but it has the premium performance, range, and versatility to match the price. The transmitter in this device has at least double (maybe triple) the range of any other Bluetooth device that I have used. The superb sound quality and capability to use two pairs of wireless headphones at the same time, makes this my new favorite device!

5 stars because it works great I'm using it right now on an old stereo that had no Bluetooth

Tested on an older TV and a newer smart tv. This device works better than I anticipated. Easy to use and understand. It works great with two headsets paired. It has long range, I can walk from the living room to the back room and still hear the tv. There is no latency! The audio runs perfectly in sync with the screen. I did my research when looking for a good Bluetooth transmitter and it lead me to this device. In my opinion, Best bang for your buck.

Long distance Bluetooth communication. Set up fairly simple. I use mine to transmit to my headphones, but a second pair can receive the signal as well. I performed a range test by going outside to the farthest point in my yard. I concur it can transmit the 100-feet listed in the specs. The Aluratek Bluetooth has inputs say from your TV or computer that can be used to add a Bluetooth transmitter to a device that doesn't have one built in. But it can also receive Bluetooth audio. Say from your phone or laptop to an amplifier in the garage with attached speakers. Dual purpose. Okay, the only bad thing I have to say is why not supply a power brick? You are forced to find a USB power source, be it your laptop or another power brick or charger that the USB cable can be plugged into. The cord they supply is plenty long. For what it is designed to do, the Aluratek xmitter/receiver will do the job, clearly and without any latency in the video to audio sync.
