Review: Works perfectly - I have found the sound quality of this DAC to be first class. It plays flac files (and others) with crystal clear quality and mp3 files are a treat to listen to. It's solidly made and small enough to be unobtrusive. The two main advantages for me are firstly the fact that it has two headphone outputs, a 3.5mm and a 4.4mm one allowing for the use of balanced cables, and secondly that it has an independent volume control that allows fine adjustment of the level. This is a massive bonus as the steps on my smartphone are either too quite or too loud with no happy medium. The buttons on the device have a nice feel to them and give the impression that they will have some longevity. There is a small led light that changes colour to display the quality of the file you are playing (a nice touch!) Lastly it is sold at a very competitive price, in my opinion you get an awful lot of value for your money. Music sounds fantastic through this little device, I for one can thoroughly recommend it, it's an easy five stars. Review: Awaken your ears - Works well. Awakens my ears to lossless music on Tidal.

Awakens my ears to lossless music on Tidal. A must for anyone with access to lossless streams and decent headphones ### ⭐⭐⭐⭐ This will not work properly with every phone *by G***G on 30 September 2025* This dac has an excellent sound and is well worth the cost. When paired with a good pair of I.E.M's the sound can be astounding , there is however one caveat, not all phones have the ability to interface to this leading to stuttering sound and playing slow. This is no fault of the dac and is a problem with the Android system and phone software, I have found no problems when used on two different tablets and I can recommend this as a very good purchase. ## Frequently Bought Together - HiBy FC4 Headphone Amplifier Portable DAC with 4.4mm and 3.5mm Headphones Outputs Support MQA16X PCM768K DSD256 High Driving Power for Android/iOS/Mac/Windows - GUCraftsman OTG Cable iOS to Type C/USB C Headphone Amplifier Cable 6N Single Crystal Silver for FiiO BTR5 Q1 Q3 Q3s Qudelix 5K xDuoo Link2 XD-05PLUS E1DA 9038G3 9038S 9038D for iPhone iPad iPod Touch - okcsc DAC/OTG Cable - High-End DAC/Amplifier Adapter for Type C Headphones, Compatible with FiiO K3, Khadas Tone 2 Pro to USB C Mobile --- ## 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.vu/products/470265506-fc4-headphone-amplifier-portable-dac-with-4-4mm-and-3](https://www.desertcart.vu/products/470265506-fc4-headphone-amplifier-portable-dac-with-4-4mm-and-3) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-06*
