Nobody is perfect. I loved the look; it came on time etc. However, the plug in was not flush enough to allow full sound from both sides to come through the headphones. After trying all the troubleshooting the manufacturer had me do, it was clear it needed repairs. I returned it. ### ⭐⭐⭐⭐⭐ Five Stars *by O***U on April 27, 2017* Superlative dac amp combo. using it on a daily basis with my iMac --- ## 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.sc/products/74016213-2nd-gen-wa7-fireflies-headphone-amplifier-dac-in-silver](https://www.desertcart.sc/products/74016213-2nd-gen-wa7-fireflies-headphone-amplifier-dac-in-silver) --- *Product available on Desertcart Seychelles* *Store origin: SC* *Last updated: 2026-04-23*
