"I recently took a 14-hour flight to Japan, and the Twelve South AirFly Pro was a game-changer. It allowed me to use my wireless headphones with the in-flight entertainment system. Setup was incredibly easy—just plug it in, pair my headphones, and I was good to go. The sound quality was excellent, with no lag or issues, even when using two pairs of AirPods. The battery life was impressive, lasting the whole flight with charge to spare."

"I bought the AirFly SE primarily for long flights to connect my AirPods to in-flight entertainment, and it worked perfectly. The audio was clear, with no noticeable lag or interruptions. It’s super simple to use—just plug it into any 3.5mm audio jack. My only minor concern is the battery life could be a bit longer for extended trips, but it's a small price to pay for such a useful device."

"I love my AirPods Pro but could never use them on long international flights until I got the AirFly Pro. It allowed me to pair two headphones and stream music from my phone to the unit.

"Using this in TX/Transmitter mode with my TV and soundbar has been relatively easy, but I've noticed some issues. The latency is minor in SBC mode, but there’s an annoying volume reset when reconnecting my soundbar. If these problems aren't deal-breakers for you, it could work well."

"I was pleasantly surprised by the compact size of this UGREEN Bluetooth transmitter/receiver. It's about the size of a small thumb drive but feels quite hefty.

"I bought this device for my old stereo receiver and it works perfectly. I connected it using an adapter, paired my Sony headphones, and it was seamless. I also streamed music from my phone, which was a delight. Plus, it's small enough to fit in my headphones' case, making it perfect for travel!"

"This gadget is a game changer for my flights! In Tx mode, I plugged it into the airplane screen and paired it with my AirPods, allowing my friend and me to enjoy a movie together. The Rx mode let me connect it to speakers, enhancing my Peloton experience. I'm extremely pleased with this dongle's performance!"

"I received my transmitter but it was missing a cable. After returning it, the replacement arrived complete. Setting it up was a breeze after skimming the instructions.

"Using the SOOMFON Bluetooth 5.3 Audio Adapter with my vintage receiver has been great. It took me just two minutes to set up, and I started streaming music immediately.

The sound quality is fantastic and the Bluetooth signal is strong! I bet it would work well with AirPods or headphones too!"

"I bought this transmitter for its 5.2 Bluetooth version and Qualcomm aptX HD codec to avoid lip-sync issues while watching TV. It paired seamlessly with my AirPods and Soundpeats Q30. The volume control works only for one channel, but I managed to get full range control through my TV remote. The sound quality is excellent, and I appreciate that it hides neatly behind the TV!"

"Using two Bose Mini II speakers for our TV has been great. After switching to this transmitter, both speakers connected immediately without any issues. The latency is barely noticeable, and the LCD screen lets me easily choose my connection. It solved our sound issues in minutes, and I highly recommend it for anyone struggling with sound in larger spaces!"

"I purchased the UGreen Bluetooth Audio Receiver & Transmitter for my Zune HD. After using my Zune almost daily since 2010, I wanted to upgrade it to Bluetooth to prevent further damage. The setup was tricky at first, but I figured out the settings. The sound quality is excellent, and it doesn't add weight to my Zune. Unfortunately, the controls didn’t work with my JBL speaker, and it wouldn't connect to my XO Beach 3D headphones."

"I chose this device for my stereo that lacks Bluetooth. It's been a lifesaver while working from home, allowing me to enjoy music without disturbing my spouse. Initially, it had trouble connecting to my earbud, but after resetting it and clearing the area of other Bluetooth devices, it worked perfectly. Now I can enjoy music at a comfortable volume without worrying about bothering anyone."

"I bought the UGREEN Bluetooth Transmitter and Receiver to connect my ThinkLabs One Stethoscope to my Bluetooth hearing aids. It works like a charm! The setup was simple, and it reconnects effortlessly. While the sound isn't as loud as with headphones, increasing the volume on both the stethoscope and my hearing aids makes it a great alternative. I highly recommend this product!"

"I found it easy to hook up and learned how to use it quickly. Every Bluetooth device I connect works seamlessly, and the range is impressive. As someone who is hearing impaired, I appreciate being able to use earbuds, a Bluetooth speaker, and headphones without disturbing my family. I’ve already purchased a second one!"

"I have this Bluetooth transmitter connected to my stereo amp for late-night TV watching. It has great range, and I can use my Bluetooth headphones throughout my house. However, I've noticed a slight delay in dialogue matching the lip movements, which I think is common with Bluetooth."

"After trying several devices that didn't work, I finally found this one. It's simple to use and connects easily to my TV with an optical cable. The sound is clear with no interruptions, and I appreciate the screen display showing detected devices. I highly endorse this product!"

"I am absolutely thrilled with the Swiitech Bluetooth Transmitter! This little device has transformed my audio experience. The setup was incredibly simple—just plug it in, pair my device, and I'm good to go! The Bluetooth connection is stable and fast, allowing me to enjoy music and podcasts wirelessly without interruptions. The sound quality is impressive, with clear audio and no lag, even while streaming videos. I'm particularly enjoying using it with my stereo setup for late-night record listening. The compact design is a huge plus too; it fits easily into my bag, making it perfect for travel!"

"I recently bought the Swiitech 2-in-1 Bluetooth Transmitter and Receiver, and it has far exceeded my expectations.

Watching movies or gaming with Bluetooth headphones is smooth and lag-free, which is fantastic. The ability to connect two devices simultaneously is extremely convenient, especially for sharing audio. Its compact and sleek design makes it perfect for travel, and the impressive battery life allows for hours of use without needing a recharge!"

"We purchased the Swiitech Bluetooth Audio Transmitter for our bookshelf Yamaha stereo system, which lacked Bluetooth functionality. I was about to list my beloved pink stereo for sale because it only played CDs and radio. Thankfully, my husband found this Bluetooth device online, and we couldn't be happier! It connects seamlessly to our cell phone, allowing us to play music from Amazon Prime or YouTube. The compact size and long charge hold make it a joy to use, saving our cherished sound system!"

"I have an ancient iPod mini that I cherish for running. It’s compact and fits perfectly, but lacks Bluetooth. This affordable gizmo connects to the earpod port and transmits Bluetooth to my Samsung earbuds. The cord is sturdy, allowing it to stay stable while I run. I sometimes tuck it into my waistband, and reception remains strong. The volume control works, but pause and stop functionalities don't, which is fine since I manage that on the iPod. As a casual runner, I haven't tested the battery life extensively, but it hasn't posed a problem for me. Just a heads up, now I have three devices to charge!"

"I really appreciate how straightforward the setup process was. The user manual was clear and made everything easy to understand. Once I started using it, I was genuinely impressed by its performance and reliability."

"I bought this to use my wireless headphones with old tape decks, and it works like a charm! The Bluetooth transmitter is fantastic, allowing me to connect my older devices to my Bluetooth earbuds effortlessly."

"I didn't expect much from this product, but it surprised me. Using it as a Bluetooth receiver, it has modernized my vintage stereo amp. Pairing was seamless, and the sound quality is perfect. It's also portable with good battery life. I did find some conflicting information in the manual, and the voice during pairing is quite loud."

"This device is perfect for my 2011 Jeep with a CD player. It allows me to enjoy Bluetooth music, although it doesn't work for phone calls."

"I use it with my room TV to connect a speaker by my bedside since I don't hear well anymore. It's perfect for my needs."
