This is the Flagship IEM from FiiO. My very first IEM was the FiiO FA19 and I thought that was the best sound I've ever heard and better than any headphone or earbuds I have or heard and so I was wondering after listening to SoundNews Review could the FX17 really be much better? Answer: Yes the FiiO FX17 are absolutely brilliant. The USB connection and the PEQ work well plugged into FiiO M17. The best EndGame Sound is when the FX17 is plugged into the iBasso DX340. Highly. The FX17 is FiiO's best IEM. They fit perfectly in your ears like the FiiO FH19 do and the cable is much better than the one you have with FA19 and FH19 which is Gold, Copper and Silver and interchangeable connections. AndyAudioVault called the FA19 the Supreme Being (Fith Element) - The FX17 is THE ONE (NEO The Matrix). Highly Recommened.

Excellent device. Superb sound and price. Quick delivery. Thank you!

Awesome dap on a budget, coming from a Fiio x7 this is just perfect in any way, the UI is so smooth and the audio quality is superb. Ordering it was so straightforward and fast delivery. Thank you

Lot of value if you're experimenting on how to tune iem's but ultimately Final Audio type E, Divinus Velvet and Eletech Baroque tips are the next level in refinement though this selection will help guide you towards the right top tier choice and ultimately may prove to be good enough to settle with.

Audio performance of the RU7 gives every element in the soundscape body and makes you feel you've got prime position front row. The high frequencies have a welcome sweetness and sense of harmonic ring that lesser digital sources will fail to flesh out. The bass has the most body in the upper range yet able to create a commendable sense of depth in image like few others. As a portable alternative to the chord mojo2 I find it capable of deserving a chance to shine with higher end iem's where in comparison to the questyle m15i that shows a limit to its capabilities. On the negatives it runs hot just a little above 42 degrees Celsius and I advise against using the very nice leather case. Another quirky negative is occasionally you'll come across a recording it just doesn't seem able to convert to DSD and you'll get timing issues and audible drop out. Having picked this unit up at reduced price in excellent condition and with full accessories intact I'm incredibly happy with it's loveable character and tonality that far outweighs it's heat and rare encoding issues.

Great little cable. Works with HIBY M300 and Shanling M0 pro but doesn't work with Shanling M1s. Used it with Cayin Ru7 and questyle m15i DACs. Overall a fair improvement with dynamics and staging and my Duracell power bank gave the best sound from a choice of many. If you use a dap as transport and a separate dongle Dac then it's easy to recommend trying it out You're sure to get you £19 worth of investment rewarded. Construction looks likely to be pretty durable.
