Very useful. Sound quality also good. 4.5k price shall be reasonable. 5k and Above not justified. ### ⭐⭐⭐⭐⭐ Sound Quality and call *by A***N on 2 August 2025* Very good bluetooth audio transmeter ### ⭐⭐⭐⭐⭐ Reasonably priced, good sound, and works well for watching Apple TV with wired headphones *by C***R on 3 August 2026* I decided to switch back to wired headphones and earbuds after using my AirPods Pro for the last couple years. I got tired of having to deal with 3 separate batteries beside my phone’s. However one of my favorite uses for my AirPods Pros was their ease at connecting to Apple TV for watching content without disturbing anyone else. There’s not really any easy way to connect wired headphones to a modern HDTV or Apple TV, so I decided to look into Bluetooth receivers I could plug my wired headphones into that can then connect to the Apple TV wirelessly. This FiiO BTR11 model seemed to be the best reviewed one for the most reasonable price. It works really well! It’s really intuitive to connect to the Apple TV. I connected it once through the Bluetooth settings and now whenever I turn it on it automatically connects. That’s actually more intuitive than the AirPods because you have to press the home button on the remote to confirm you’d like to connect them. Since I really only plan to use this thing to watch my Apple TV exclusively connection should continue to be effortless. It’s got volume controls which is nice, and a multi-function button that can play, pause, turn the unit on and off, and I assume re-enter pairing mode but I haven’t tried that yet. The DAC and amp have plenty of power, they have little trouble driving my HyperX Cloud 3 gaming headset which are surprisingly high impedance hard to drive for a gaming headset. They of course drive my JBL Tone 110 earbuds effortlessly to my usual listening level at only half volume. There is also no latency on video content which is handled by the Apple TV automatically adding a few tens of milliseconds delay to compensate. There is a slight delay on the browsing sounds in the menu that I don’t think the AirPods have but that doesn’t matter. They also have much more range than the AirPods, I can move around to almost any room in the house and it doesn’t glitch or drop connection from the Apple TV. Battery life seems to be solid, and of course it’s easily rechargeable by USB C. The spring clip on the back is nice too, I can clip it to my shirt pocket and it stays out of the way while I’m watching TV. There’s also a built-in mic for phone calls but I probably won’t really use that feature. Overall very happy with it, especially for the price. I got the green “Snowsky” branded version and I like the color, it’s brighter than pictured, a sort of avacado and I like it because it’s unique among electronic devices these days. ## Frequently Bought Together - FiiO BTR11 Bluetooth 5.3 Receiver LDAC 3.5mm Wireless Audio Headphone Amplifier Adapter (Black) - Moondrop CHU II High Performance Dynamic Driver IEMs Interchangeable Cable in-Ear Headphone - Anker USB C to 3.5mm Audio Adapter, Male to Female Nylon Cable for Samsung S20/S20+/S20 Ultra, Pixel 4/+ 4XL, and More Type C Devices --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/729636504-btr11-bluetooth-5-3-receiver-ldac-3-5mm-wireless-audio](https://www.desertcart.at/products/729636504-btr11-bluetooth-5-3-receiver-ldac-3-5mm-wireless-audio) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-09-25*
