## Description

FiiO FD3 PRO Earphones hi-res 1DD in-Ear Monitors MMCX Connector Flagship-Level DLC Diamond Diaphragm Black

Review: Incredible sound. - Incredibly clear and very rich sounds. I bought these a few week ago. They've taken some time to find the right fittings for my ears. The black and red fittings that come with the earphones will give you more bass, plus there are small metal filters that unscrewed from the earphones, they are the red ones, best for more bass. The vital thing is that the fitting is right for your ears to achieve the bass. I also use the equaliser on my samsung phone it works very well to adjust the required sound. They are the best earphones I've bought. I used to have skullcandy but these a red a big step up. One more thing the usb c connecter I'm using is a Hi.Dac 32 bit which I would recommend for these earphones. There are no controls on these.
Review: Sonic Bliss - I have a mixed relationship with Fiio, mainly down to a disastrous experience with their X5 DAPs, but after losing one set of wired IEMs to a car door, I started reading around and looking at alternatives. I tried the Letshuoer S12 Pro but couldn't for the life of me get them to stay in my ears (freakishly wide but shallow, apparently) and the Fiio FD Pro looked interesting, so I gave them a go. And am very, very glad. These are, I do believe, the best pair of wired IEMs I've got, and that includes a pair of Shure SE215s (re-cabled to go into a 4.4 balanced plug) and a pair of Moondrop Arias. They have their virtues, for sure, especially the Moondrops, but the Fiios take listening to music to a whole different level. I use them on my Shanling M6 DAP on a mixture of sound formats (ogg vorbis, FLAC and High-Res) and genres and the sound is expansive, clear and punchy. I can see how some might find them a bit harsh, as certain bands I've listened to have tipped slightly over the edge even for me, but I'm now armed them with some Sonicfoam large memory foam eartips which has made the sound warm and oh-so beautiful. I also absolutely LOVE the ability to switch jacks and use either 3.5mm or 4.4mm, such a wonderfully practical thing and so simple. These are the kind of earphones that I end up listening to almost my whole collection all over again, finding new details and nuances and ways of listening to well-worn tunes. Excellent, and balm for my battered soul.

## Questions & Answers

**Q: How long is the cable from jack to the inears?**
A: From the connector plug to the wire divider is 80cm, and from the wire divider to the ear piece is 30 cm, so 110 cm in total.

**Q: Is the pro cable a balanced cable?**
A: The cable supplied is a balanced cable, it comes with 3 interchangeable plug terminations, a 3.5mm single ended plug, 2.5mm balanced plug and a 4.4mm balanced plug. To buy the earphones and this cable separately would cost considerably more than this Fiio FD3 pro set costs. Hope this helps.

### ⭐⭐⭐⭐⭐ Sensational sound/Great price
*by C***L on 3 April 2026*

Superb when paired with the Fiio D15 R2R CD player/transport. Have a listen to the CD by Bob James - 'Feel like Makin' Live' which has been immaculately recorded (read the sleeve notes how they did it) - Rhodes & Piano/Double Bass/Drums. - Absolutely sensational on the Fiio FD3 Pro earphones. A great product at a reasonable mid-price range. Highly recommended if you're serious about music!
