FiiOFH3 HiFi Earphones 3 Drivers (1 Dynamic + 2 Knowles BA), In-Ear Earphones High Resolution, Bass Sound, High Fidelity for Smartphone/PC/Tablet

For comparisons my frame of reference is the following IEMs:Campfire Audio Dorado 2020 (£1000)Thieaudio Monarch MkII (£850-£1000)KZ ZS10 Pro (£45)Sources:Sony A55Hiby R5 Gen 2NAD M33After my KZ ZS10s broke after less than a year, both lost all bass so possibly the bass drivers failed, I needed a replacement. I wasn't displeased with the KZs and my only complaint was that they could be quite sibilant at times, depending on the track. For most Music I listened to though it wasn't a problem but when it was there it was very harsh and shrill sounding.I purchased the FH3s in early 2022 and the difference was noticeable. In sound and in build quality. Yes the FH3s are more than 2x the price of the KZ ZS10 Pros but in audio paying more doesn't guarantee a better product or even any improvement. The gains are only marginal, typically. The build quality of the FH3 is fantastic and I find the fit the most comfortable of any IEM that I have tried. Great cable too, including the curved hook parts that go around your ear. Can be worn for hours on end with zero discomfort. The FH3 sound is superior to the KZs. A more weighty Bass, less harsh mids and smoother treble. It is quite difficult to encounter sibilance using the FH3s, not only compared to the KZs but also my Campfire Audio Dorados and they are £1000 IEMs! So the sibilance is less on the FH3s than the Campfire Audio Dorados. The Dorados have slightly better detail, imaging. The instrument separation difference really is paper thin between the FH3 and Dorado. When I say slightly better I am talking very small percentage terms, 5% at most. The Bass is nearly on a par too with the Dorados having a tad better controlled or tighter Bass than the FH3s.Similar degrees of differences when comparing the FH3s to the Monarch MkIIs. The Monarchs had the best instrument separation, layering, imaging and detail of any IEM that I have heard and they also had the most weighty and deep bass but the FH3s come very close. Unfortunately, for me, the Monarchs were too big and didn't fit properly so I sold them.In short, the FH3s compete with £1000 IEMs and the difference is 5% at most. They have great bass and are well balanced with great detail. The fit, comfort and build quality are all excellent too.

I've owned several pairs of headphones and some earphones in the £240 to £300 price range but I think these earphones beat all of them, perhaps by some margin, while being small and light enough to carry anywhere.Also good for blocking out external noises (eg on the train) and sound leakage (I expect) is minor so you don't disturb others.It looks like they need less power to drive than most headphones or earphones - useful for preserving phone battery life. When I plug these into my iphone I can set the volume a lot lower than with other headphones to enjoy the same sound level.The only possible flaw I can see is they are more fiddly to fit in your ears than other types of earphone or headphones - but probably this is a big part of why they sound so amazing and block the world out so well.Awkward say if on a flight and you think you should check what the latest tannoy announcement is.So they are best suited to when you want to really get immersed in music - when they are simply perfect.I use mine to listen to many sorts of music on spotify at the top sound quality level via an iphone - and the sound is superb. I hear lots of things in familiar tracks that go unnoticed with lesser earphones.Note that for the above setup which lightening to 3.5mm adapter you use dramatically effects how good the sound is. Alas Amazon tend to cancel my reviews if I mention other items they sell so I can't recommend one (well they refer me to a massive essay on every possible reason my review has been blocked - so it's very hard to figure out how useful I can make this review).The other possible downside of these earphones is they are so good and immersive that when listening to great music, if you shut your eyes, you won't notice if the world ends! Well except when your sound source stops. So use in a safe space.

First of all I’d like to start of saying I returned these. But I’m still giving it a 4 star for the following reasons: the sound quality is fantastic, and build quality feels premium. I used these originally to play games and listen to music with at my PC as I was getting sick and tired of wearing over-ear headphones. So I got these recommended to me by a friend. Like I said previously these sound great, and the materials they have used to make these earphones feel very good for the price. However I found that my ears would get quite sore after wearing these for an hour. I tried all the different ear tip sizes but I kept on having the same problem. So I returned them. For now I will stick with my over-ear headphones.Overall I’d recommend these for someone looking for budget yet high quality earphones.
