Yeah I did, I tried a lot of tips but they are still very uncomfortable to me so Iām not keepong them. Luckily I can return them. Thanks for the tip 
Curious if any other FD5 owners are getting an uneven fit? Iāve rolled a bunch of different tips including all the stock ones and various Spinfit and Azla and even tried different sizes on each ear but can not for the life of me get the same seal/fit in both ears 
. Wonder if itās due to the weight or perhaps unit variation. My lighter IEMās all seal just fine but damn it I love these and donāt want to give up on them.
All the stock tips seems to be fitting very well with me. I just happen to prefer the CP145 (M) on my FD5 while I use the CP100 (M) on my FH3. The CP145 (M) seems to be loose on my FD5 nowadays and it comes off a lil bit too easily. I may need to get a smaller cp145.
I donāt have a problem with uneven fit regardless of tips. But you certainly do feel how big they are in your ears. Thereās some slight pressure compared to when Iām wearing my Starfields. It could also be the default small bass tips being a bit larger than Iām used to, but I think they have the best balance in sound.
Best fit for me is the Spinfit cp360, however I donāt quite like how they change the sound, otherwise I prefer them with pretty much every other IEM. I reckon the small cp100 would also fit me well, just havenāt gotten around buying any.
These just arrived. Was going to share my impressions here, but instead the right earbud does not work. Anyone else have this problem? I have just contacted amazon to see what I can do about it
First time I have seen this being reported.
Have you tried switching the cable (L/R) to confirm it isnt the cable that is dead?

Iāve done that, and only the left works. So it must be a problem with the connector on the earbud or the driver itself
That seems to be the case then. Amazon should have your back though.

Iām new to iems. Fiio in general, are they reliable?
Fiio is one of the chi-fi brands with better QC and quality than the competition in my experience.

Just stay away from their true wireless earhooks, those have a pretty high failure/issue rate especially the UTWS3 version.

I learned this the hard way. Twiceā¦
Usually, the fd5 are the portables i pick up when I leave the house but decided to throw them on the home setup and yes a better dac will benefit the fd5.
I was wondering if dacs also mattered for iems and yes they do if one is looking for better dacs for better performance.
With the asgard 3 i used the e30, micro bl, and ares II.
E30 had an edgy sound with good 3d spacial creation, micro bl steps up in resolution and provides a cleaner sound but when jumping to the ares II, it was clear that the ares was providing that little extra that makes the fd5 more enjoyable to me and makes me want to grab them when im at home.
The ares brings an organic/natural sound with better seperation, more body, and smooths out the mids while maintaining high resolution compared to the e30 and micro bl.
Also powered up the crack w/speedball and liquid platinum paired with the ares and the fd5 really perform.
I had a similar experience as well. Been exclusively using the FD5 on my Sony A55, but after getting the Fiio Q3 just last month, the changes and improvement in sound really are quite a lot. The treble are smoothed out and the mids, especially on the vocals are more lush (But still has that vocal sibilance). The bass still sounded good so I couldnāt tell if that part is an improvement or not.
Staging and imaging really got a huge bump and it took me a while to get used to the very wide but detailed soundstage.

How are you using your fd5 - with main wide bore or with narrower ?
With narrow it shouldnāt be sibilance or at least i canāt hear it. Of course not all like this narrow bore because of smaller soundstage.
I remember when i got them first and with original ābalanced tipsā with wider bore there was something i could call sibilance but after using cp145 tips even with wide bore there is much smoother in this region.
And fd 5 really souds event better with proper dac and amp. I like them a lot, A LOT

Smoothing out the vocal sibilance or edgy -ness was exactly what i felt the fd5 needed. Lush fd5 vocals hits the spot for me.

I am not exactly a fan of the narrow bore so itās been the main one. Yup! I had been using the CP145 for a few months and then switched to the CP100+. Staging felt more open and detailed with this tip but of course, the sibilance, unfortunately are still there. I could be sensitive to the treble peaks and the highs.
Listening through on a dac/amp really does help smoothen out the treble a lil bit and made the vocals much more better. I am thinking on finding other tips to help smoothen out the treble and sibilance just a tad more. Iām close to finding the right preference for my FD5 listening needs.
Yeah, I came to a similar conclusion as well. The FD5 has a lot of potential to be an IEM to stay for a long time but it needed some personal tip rolling and listening to it on a dac/amp or a decent DAP. I spent an entire day one time just listening to Jazz and it was heavenly!
