FIDUE A71

These have enough bass and good mids but let down by treble which is veiled with no details. I bought BLON BL03 and Tempotec Sonata HD Pro from Hifinage these are super hit in my collection and also BLON BL01 Bass & clarity/micro details at less price is also exceptional.

I can imagine why Fidue A71 unsold having mfg 2014 for a reason. Newer generation IEMs will blow this away in price/performance.

Lets go in depth

Low(Bass)10/10 :- These were rather exceptional here, the kind of control and oomph is rarely felt in any earphones. The bass was very well controlled with sub bass tight and of very high quality. This is truly the result of the genius design and it shows where they have tried to be unique and it pays off.

Mids(9/10):- Forward mids, the overall signature can be called a slight V with highs a bit recessed. The lower mids are beautiful as well the upper mids. One thing I absolutely loved in these earphones that the imaging and resolution is simply outstanding. The mids are very pleasant and very distinct. The seperation is simply astounding.

Highs(7/10):- Now the 7 doesn't mean they are poor, I would generally give the KZs and Tin a 5 here, the highs are really good for an IEM, in fact I felt it was one of the best presentations even amongst the Hi-res earphones.. Don't know why these are not Hi-res, must be.. The details, the chimes and follow-throughs are perfect. I have has treble cannons that had poorer imaging than these.

Resolution/Imaging/Sound Separation (8/10):- This is the strong suit of this IEM. these were outstanding here. they punch way above their weight category. The dual acoustic chamber does its job here.

Sound stage(8/10):- Bigger than your typical earphone. In fact, the sound stage is wide which makes the imaging and separation even better.

Overall (9/10): These have a snug fit if you find the right fit of buds. These are bang for your buck, and I don't say that about anyone.GO FOR THEM...

There is no price and manufacturing date details on the box. It seems it is very very old . While taking out the earphones from the box the sleeve near 3.5MM jack and Y splitter which supposed safeguard the cable worn out in to pieces. I didn't expect this kind of product from Hifinage. I am very much disappointed, even your exchange policies are not at all customer friendly.
Again the delivery took 5 days which is quite high compare to other online portals.
Even the audio quality of earphones also not as expected, it's muddy bass. If you want enjoy these earphones you have to buy a decent DAC. With Fiio BTR5 this earphones are sounding good.

This iem for the price is probably the best bass-oriented ive ever used. The bass is tight, not ear fatiguing, the mids are very forward and in your face, while there is just enough treble emphasis as to keep u in the mix. The only issue i faced with this iem is the fitting, they refuse to give me a good seal like my KZ ZSX, i've tried every included eartip and the one which doesnt fall out is the small dual flange but then there is no sub bass with it. I am currently using it with a pair of RHA eartips which seem to give a good seal if i wear the earphone down instead of around the ear.
Sound quality 9/10
Fit 6/10
Comfort 10/10 --> extremely light, u barely feel it unless its falling out

Sub-woofer like bass with forward mids and just enough treble detail without peaks or harshness. These were top bass cannons from 2016 but are still relevant today. The bass is not sloppy, relatively fast bass compared to other bass heavy IEMs. Great for electronic music. Bass can be EQ'd down for acoustic and jazz.
