Ok so curiosity got the better of me, no harm in owning loads of headphones right?
I'll start off by saying my thoughts are that the Cambridge Audio Melomanias blow the FIIL T1x completely out of the water, but here we are comparing a £99 IEM to a £55 IEM.
The FIIIs are decent, don't get me wrong, straight out of the box they are quite pleasing, almost a more 'fun', brighter and forward sound whereas the Melomanias are much more balanced and refined.
The FIIIs have quite a recessed midrange compared to the Melomanias, the FIIIs also have a much harsher top end, which gets quite fatiguing. The bass is there in the FIIIs but it is not overpowered. With faster rock & metal songs the FIIIs can get a little lost and muddy whereas the Melos handle this brilliantly and seem far more agile.
The build quality of the FIIIs feels a lot cheaper compared to the Melo's, the battery life of the FIIIs is also much poorer in comparison.
Comfort-wise this will be pretty subjective but again the Melos feel more comfy, secure and lighter whereas with the FIIIs I haven't quite found the perfect fit yet.
The Melo's are quite honestly one of the most pleasant surprises I've ever had when buying tech.
I'll keep the FIIIs for occasional use so I'll look forward to seeing how these pan out after they have fully burned in. The app is working ok for me and it looks like there are some good options to tune the EQ from within the app, for £55 they look like decent enough value
