Works perfectly and delivers great sound.All included items worked and the fiber cable is of good quality. Amazing value. ### ⭐ Converter Not Working *by G***S on August 29, 2017* I connected the power cord to an outlet...connected the optical cable to my TV and to the converter...connected analog audio outs to receiver...no signal to receiver. ### ⭐⭐⭐ Excellent seller, a bit of a problem with the converter(s) *by V***F on November 13, 2017* This is a nicely packaged unit, and it has all the requisite inputs (coax and toslink), a pilot light to show (what else?) power, and RCA jack outputs. It installed quickly using the supplied (standard) USB supply (5v, 1a), and it sounds pretty good. So why only 3 stars? Because, to me, it only sounds pretty good. I'm not talking "golden ear, oxygen-free cable" pretty good - I'm talking about a low-level buzz in the background. Only really audible on the quietest passages (or when the source is paused) and the system volume is pretty high while in a quiet room. But the buzz was measured at around 60mv P-P, with a whole slew of harmonics. I seem to be the only reviewer who has found fault with this unit, but I have tried 3 separate units (Dinger was SUPER nice, and did everything they could to try to help), using 3 different digital sources on 2 separate sound systems. I finally disconnected it from any output except an oscilloscope, and the result is the picture I'm enclosing; this is hooked to a CD player coax output with the player in pause. I tried alternate power supplies in hope that might have been contributing, to no effect. If anyone else can confirm or tell me I'm wrong, I'd appreciate it - as I said, the seller is perfect, and the price of these is certainly excellent.Just a quick update - I ordered another manufacturer's unit; similar specs, almost 3x the price. It worked perfectly - virtually silent when silence was called for. --- ## 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.jp/products/44956163-headphone-amplifier-portable-3-5mm-audio-rechargeble-hifi-earphone-headphone](https://www.desertcart.jp/products/44956163-headphone-amplifier-portable-3-5mm-audio-rechargeble-hifi-earphone-headphone) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-11-04*
