Three inputs (RCA, 1/4", 1/8") and two physical outputs (1/4" & 1/8" per output), mute on inputs, and stereo/mono switch offer a high flexibility of configuration. The bundled power adapter is a USB power adapter, so you can use the power cable to power it using a power bank also. ### ⭐⭐⭐⭐ Godd gear to have *by A***E on 4 November 2022* Good for singers and musicians live performances ### ⭐⭐⭐⭐⭐ Excellent sound but loud pop when powering on *by B***J on 15 March 2023* I use it on my PC to split signal among earphones and Amp+Speakers. Sound is excellent! I was using the Fifine N6 which is also very good but does not have a power button. This one comes with a power button which is nice. Also this has both quarter inch and 3.5mm output sockets for each channel so no need for adaptors to connect any earphone. But the only complaint I have is that it makes a rather loud popping sound when switching on. --- ## 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/378626356-hayden-hy-i4ii-4-channel-headphone-amplifier](https://www.desertcart.vu/products/378626356-hayden-hy-i4ii-4-channel-headphone-amplifier) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-08*
