Design & Build Quality
If you follow my reviews, you know I really like all-metal devices and the FD1 is one of those. It is simply beautiful and it does not look like it is a $59 usd device. There are gold rings around the balanced and single-ended outputs and those add richness to the visual package. Buttons and sockets feel solid, durable. No wiggle-wobble. It is quite small too, it is just 61.5*61.5*9.5 mm and 71 grams. It is the perfect companion of the R2. It does not have a power button, it automatically powers up when you plug it into a source. That’s convenient.
It supports every audio file type and it can offer native DSD decoding up to 128. You can use bit-perfect mode with Android via USB Audio Player or HiBy Player app. Both offer bit-perfect USB audio playback. HiBy included a USB mode switch, if you run into compatibility issues with the devices, just go ahead and try USB 1.0 instead of 2.0. I mentioned that it is mostly driverless however, DSD playback requires drivers to be installed on your preferred device. As for drivability, the balanced output is rated at 75mw whereas the single-ended one is only 25mw. A balanced output would be enough for most of the IEMs in the industry so that’s good.
FD1 – Sound
The HiBy FD1 has this slightly warm sound signature. Bass extension and impact is great. Bass is quite powerful out of the balanced output and it is controlled. Midbass is similar to R2. No bleeding to midrange at all. As for the midrange, it sounds slightly thicker than the R2 and vocals are more meaty. Instruments have enough air between them just like R2 but the width and depth is slightly better. Midrange is clear and precise.
Upper midrange is controlled, no sibilance issue here, either. Treble is detailed but smooth. Resolution is really good for a $59 USD device. It feels resolving when combined with an IEM like Earsonics Velvet v2. Dynamics and PRaT are really good for the price as well, congestion handling is tad better than R2 so sandwiching them together will be quite interesting.
