It takes minutes to set up and ready to go in no time. The sound quality is really amazing and we are all very happy with it. It works well with multiple iPhones controlling it. To add a new device, just disconnect from the current one, then connect from the new one. Once it's setup, any device can jump in any time, just pause the music then connect... I will recommend this product! ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Perfect Bluetooth option if USB and AUX close together *by M***I on Reviewed in the United Kingdom on 10 May 2018* Got this today as I upgraded to iPhone X this weekend. Car has AUX and charging port close together so paired this with a USB charger for the cigarette lighter port and was in business in less than 60 seconds with a crisp Bluetooth connection. Can't beat this for something that is unobtrusive and gets the job done. The end glows when it's powered on and connected. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Great little piece of hardware, proper innovation *by A***S on Reviewed in the United Kingdom on 19 December 2016* Great little piece of hardware, quick connection to the phone was made, my only issue is that a wire has a slightly better sound quality (given the radio / radiation disturbances of other appliances in the vicinity. --- ## 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.co.uk/products/132971272-tunai-firefly-bluetooth-receiver-world-s-smallest-usb-wireless-audio](https://www.desertcart.co.uk/products/132971272-tunai-firefly-bluetooth-receiver-world-s-smallest-usb-wireless-audio) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-06*
