Review on FiiO FD3 Earphones Hi-Res 1DD In-Ear Monitors MMCX Connector Flagship-Level DLC Diamond Diaphragm 4 Strands Of High-Purity Monocrystalline Copper Wires (Silver) by Lisa Holland

I have been using FH3 as my daily IEM for about 6 months and FD3 is totally superior to it.1. Single DD means you don't have to rely on different driver technologies to work together, no sometimes odd BA timbre. Fast and punchy bass, I like to use them with many bass-heavy EDM subgenres. I was expecting that using DLC on the diaphragm instead of beryllium would be a downside, but honestly I'd say it's on par, if not slightly better than the FH3.3 in terms of bass quality. The mids can be a bit sunken in places, which I noticed especially when the bass is heavily influenced by female vocals, although they still sound full and not too "distanced".4. The highs are a bit softer, but without loss of detail, very high notes on the FH3 very often sounded strange, up to the point of stinging, depending on the song. I've looked through most if not all of my music library (Hardstyle, DnB, Happy Hardcore, House, etc.) and haven't heard it on the FD3. All in all, this is a great IEM for listening to music at a pretty reasonable price. . There's some decent competition at this price point, but you really can't go wrong for the sound and quality of these headphones. * I chose the FD3 Pro because of the interchangeable cable, but if you don't use 2.5/4.4MM Balanced, just select the standard, you won't miss anything except the interchangeable cable, which you won't use anyway use. ** FiiO support is also among the best in the US when it comes to "Chi-Fi” companies. , my first pair of FH3s actually had a dynamic driver error on one ear and I contacted them and provided my Amazon account, got a reply the same day with a California address to ship to and it took the round trip 6 days (2 to them and 4 back to me) to replace me. A little more peace of mind, which is always nice.
