Isn't it quite likely that as time goes by you either get more used to a particular sound or even have more of a psychological investment in believing the sound will be good, and so, one way or another, change your judgement simply as a consequence of changes in your biases? I'm not a sound...

600s fit. If 400s have a smaller diameter than 500s, and 500s a smaller diameter than 600s, then I’d be surprised if 400s would fit. I gave up trying to fit 500s because I was worried I’d damage the earphones.

I’ve just tried the SpinFits. Not for very long. A couple of of songs (Pure Shores, All Saints and Harvester of Eyes, Blue Oyster Cult) on each of the pairs of SpinFits and the Symbios, going through each pair of songs a couple of times on each pair of tips in a semi random rotation (so I...

Well I've used 600s which fitted well. I found 500s had too small a diameter to fit easily. I can't imaging that 400s or 300s would fit. I actually use MandarinE Symbio W (Wide Bore) which I like much more than Complys. I've just received a couple of sizes of SpinFits which I am going to try...

Just a quick thank you. I had FiiO amps years ago and they were amazing value for money. I recently got a Q5 and it too is great value for money and also stunningly high quality. The same is true of the FH5s. Keep up the good work - looking forward to seeing what comes next!

Just to add another datapoint (not totally sure how useful these are, but never mind). I got a variety set of MandarinE Symbio tips (widebore, in S, M, and L sizes) yesterday. I prefer L to M for Comply tips, but, much to my surprise, very definitely prefer the M Symbios. For me (YMMV) the...

Thanks anyway. I also thought the GR8Es looked gorgeous and their size was also attractive. In the end, though, I went with the FH5s as I reckoned FiiO would probably deliver great value for money (as I guess they do, given that they gave the 535s and the GR10Es a run for their money in your...

Thanks for this. All the detail is great (I'm not sure about scoring - as I think you also said, the weight put on different factors will vary from person to person and between different types of listening (music)). When I was buying earphones recently to replace ones that were stolen I was torn...

I'll just add a little practical (completely non-subjective) note that in the UK the Grado GR10e cost £411, the Shure SE535 cost £396 (SE535-VE £439) and the FiiO FH5 cost £229. I know people asked for comparison with the Shures, but it doesn't seem a very fair comparison to make to me. All the...

I just listened to Meddle (old Pink Floyd LP, but still ripped lossless from CD). I am completely blown away.

When I had a pair of Sennheiser HD25 headphones I replaced the standard steel cable with a copper one from a different Sennheiser model (can't remember which one) - there was a big difference in sound. I guess the better the original cable the less difference you'll notice. (BTW I understand...

I've now got the RC-MMCXB cable. It is a bit more flimsy than the single ended cable that comes with the FH5s. Swapping cables was trivially easy (I'd never done it before with MMX connectors). I am using a FiiO Q5 with the AM3A amp module. I think I hear a difference in the treble with the...

Well I am currently listening from a FiiO Q5 (FiiO AM3A amp) driving FiiO FH5s. The only non-FiiO bits are Comply tips and an iPhone as source. I am super pleased at the quality of this combination at this price. Gentle high hats off to the right at the end of Lillywhite Lilith by Genesis. Just...

I've ordered a FiiO RC-MMCXB balanced cable. I'm not sure if I should have ordered an LL4.4C which seems to do the same job, bur for more than twice as much....

There seem to be lots of balanced cables available from FiiO for these, varying in price (from amazon.co.uk) from £20 to £65. Does anyone know what the difference is between them? (I'm using a FiiO Q5 with the AM3A amp module).
