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 recently purchased FIIO FH3,had the pleasure of pairing the FiiO FH3 IEM with the LG V60, and I must say, this combination delivers an audio experience that is nothing short of spectacular. As an audiophile, I’ve always been on the hunt for that perfect synergy between source and headphones, and I believe I’ve found it.The FiiO FH3 IEMs are known for their exceptional sound quality, and when paired with the LG V60, they truly shine. The V60’s Quad DAC brings out the best in the FH3s, delivering a sound that is rich, detailed, and immersive. The bass is deep and punchy without overwhelming the mids, which are clear and natural. The treble is crisp and extends beautifully, providing a balanced sound signature that is a joy to listen to across various genres of music.The FH3s are not only sonically impressive but also well-built. The ergonomic design ensures a comfortable fit for long listening sessions, and the build quality feels premium. The LG V60, with its sturdy design and excellent battery life, complements the FH3 perfectly, making it a reliable companion for both daily commutes and extended listening sessions at home.What really stands out about this combination is the effortless way the LG V60 drives the FiiO FH3. The phone’s built-in Quad DAC delivers high-resolution audio with ease, ensuring that you get the most out of the FH3’s capabilities. Whether you’re streaming music or playing high-quality FLAC files, the audio output is consistently top-notch. The FiiO FH3 IEM paired with the LG V60 is a match made in audiophile heaven. This duo delivers an amazing quality of audio that will satisfy even the most discerning listeners. If you’re looking for a portable setup that doesn’t compromise on sound quality, this is it. Highly recommended!

I've lived with these new IEMs for several weeks before writing a review. Firstly, the positives: Build quailty is exceptional. Heavy and sturdy and all wires and connectors are of a high standard. Excellent sound - very clear and detailed and full bass (more on that below). Very impressive separation in music representation and highly recommended for critical listening. Almost reaches audiophile level. Now the negatives: It took me ages to get these settled in and set up properly. There are multitide of different sized and spec'ed ear buds, Most are utterly superfluous. I eventually fitted the Large size that worked for me and achived that 'seal' within the ear canal that allows the bass to shine and the detail to come through. They sounded great. However.... the sturdy weight of these IEMs means that the units tend to come out of their settled and sealed position within the ear. So, any movement at all and the bass is lost and the mids and highs come through sounding shrill and tinny and frankly totally overpowering and unpleasant. On the move, the units require constant adjustment back to a sealed position. That usually lasted about 30 seconds before they shifted again the the bass effectively disappears. These are not for exercise or activities or being on the move! If you are in a set place and sitting still, they are truly exceptional. If you want these for jogging / walking / gym etc, I strongly advise caution unless you have tiny ears that will allow them to be jammed into place. Hence only four stars, when I would love to have given them a Five Star review.
