The inclusion of the MMCX tool is extremely welcome, and in my opinion other manufacturers should take a page from FiiO’s book here as it makes life significantly easier when changing cables. The faceplate of the monitor shell is one for sure one of the eye-catching highlights that the FiiO FD3 offers to the consumers. FiiO is a high-end company designing products in China, and their offer is wide, ranging from Bluetooth receivers, DAPs, IEMs, Headphones and more. FiiO has always been concerning about exceptional high quality craftsmanship, and the FD3 Pro is no exception to this rule. Bass is more extended and linear with the Aria, less punchy but with cleaner rumble and more natural resonance as well as less mids bleed.

It comes with two sets of tuning nozzles, one with a thin diameter and the other with a wide diameter.

You can hear some of the magic that was present in FD5 with FD3, especially in the way FD3 is quite holographic and dynamic, engaging and punchy. They have a hint of warmth and that’s the only positive thing I can say about the mids performance of the FD3/Pro. All in all, it seem to me that BQEYZ Autumn is superior in both technical performance ,like attack speed and control and harmonic distortion, as well as tonal balance which is more cohesive, relaxed and natural. The change in height of the notes is well felt too but the notes height differences is rather more transparent now than the red filter . After the commercial success they had with FD5, FiiO decided to try and bring some of that magic to those who are more budget oriented, and this is how FD3 took place.

If you are tired of too lean, cold, clinical or thin sounding IEM, the lush and energic bassy tonality of the FD3 will surely charm you with it’s musical immediacy that is everything but boring, yet cohesive in it’s balance.The included tips are all more than usable and have a noticeable impact on the sound, thus providing the ability the fine-tune the sound even beyond the options provided by the two sets of nozzles. Again, it’s very rare that FIIO offer poor craftmanship and in fact, it seem they work harder than ever to offer sturdy durability yet keeping the beautifull design approach.
