The U2 supports OTG and comes with an OTG-compatible USB cable for direct connection to OTG-enabled phones. For iPhones or iPads with a Lightning port, a high-current camera kit is required. Newer models with a Type-C port can use the included cable directly. 2. The U2 only supports 2.0 channel stereo audio. Multichannel formats such as 5.1, 7.1, or Dolby formats are not supported. 3. Please install the required driver and files from the included USB drive, and follow the instructions or video guide to set up your player properly.

It offers a super clear signal. No power source is needed, just plug it into your device. It's nice to get lossless audio straight into your speakers. It seems well built. Functionally, it's pretty basic, just a straight connection for your device. There's no volume control nor eq. One thing, though, it seems to cut out when my iPad is bumped occasionally. I can't definitively say that is due to my iPad or the device, but that could be a concern if you're trying to use your iPad while listening to music.

Awesome laminated instruction manual. Easy install on Mac Mini Tahoe. Easy setup in Sound settings. Sound output is excellent on my VMAI sound bar. I would buy again.

High quality sound, but whats the point if your receiving end doesn't support above 192. Just get the simpler USB SPDIF Adapter for 1/3 of the price. --- ## 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.ae/products/766961481-douk-audio-u2-usb-to-spdif-converter-digital-interface-optical](https://www.desertcart.ae/products/766961481-douk-audio-u2-usb-to-spdif-converter-digital-interface-optical) --- *Product available on Desertcart United Arab Emirates* *Store origin: AE* *Last updated: 2026-06-12*
