What reviewers think

Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.

What are hifi reviews useful for? (1) Identifying products you should demo in person at a dealer. (2) Learning which products reviewers unanimously praise as the best they've heard (this means they probably are legitimately great). (3) Identifying a product's attributes that satisfy your idiosyncratic needs and tastes. Beyond that, we often discount what reviewers say because they heap praise on most products—and are often apprehensive about publishing strong criticism or comparisons between products. Further, they seldom have more than a few products on-hand, often relying on their memories to compare past products. Always listen for yourself.

  • FIIO combines Bluetooth capability, high power output, and a desktop mode in their portable DAC/amp designs.
  • They offer a high degree of user customization through their control app, allowing for adjustments such as parametric EQ and device behaviors.

K7

K19  

  • Positioning: A high-power DAC and headphone amplifier aimed at users who need robust output for driving demanding headphones.  
  • Description: Incorporates advanced circuitry and a design optimized for high-current performance to maintain clear and natural sound even at louder volumes. Relative to the K7 and K9AKM, the K19 adds more power and precise output control while being less digitally complex than the top-tier models.

K11R2R  

  • Positioning: A desktop DAC and headphone amplifier that employs a fully differential 24-bit R2R resistor ladder for superior resolution and detail.  
  • Description: Offers dual NOS and OS modes along with a high-quality electronic volume control to enhance dynamic range and clarity. Compared to the more basic K7 and K9AKM, its advanced resistor architecture and multi-stage power supply deliver lower noise and customizable gain settings.

Product Strengths

  • Excellent selection of eartips ensures a good fit and optimal sound
  • The FA19 build is very nice with a premium feel, nice and smooth, and good-looking
  • Bass performance is reminiscent of high end dynamic driver setups, while keeping the clarity and speed characteristic of balanced armature drivers
  • Provides a very comfortable fit for long listening sessions with a lightweight and ergonomic shell design

Product Considerations

  • Treble response may be too spicy for some, requiring EQ adjustments, and some reviewers note the treble is unexceptional for the price range
  • The 'HiFi mode' (bass boost) may sound bloated and muddy, compromising clarity and detail
  • The cable is a bit stiff, making it springy, which could be a minor inconvenience
  • Isolation of outside noises is only okay because there is a vent for the base driver, which lets in a little bit of outside noise

Comparisons (according to reviewers)

  • Vs 64 Audio U4S: The U4S is better overall, has better balanced bass, more neutral midrange, and smoother treble than the FA19
  • Vs Westone Mach-60: The Mach-60 is more neutral with more details and resolution, while the FA19 has a larger and deeper soundstage
  • Vs FiiO FX15: FX15 has more pronounced V-shaped tuning with a more detailed and sophisticated treble and brighter sound profile

Takeaway: The FiiO FA19 IEMs are a comfortable set of earphones that come with a great selection of accessories. They offer a good balance of musicality and technical precision making for a great sound experience.

Product Strengths

  • Uses premium materials like carbon fiber, metal, sheep lambskin earpads, and zebra wood faceplates for a luxurious feel, with excellent build quality
  • Has a mostly neutral sound signature, with lambskin pads bass response is very good with a tasteful emphasis placed on the sub-bass region, and a decent midrange
  • Provides good detail retrieval, resolution, and transparency of sound, the drivers can show plenty of information and micro detail
  • A pad swapping system allows changes to sound characteristics, with lambskin pads and breathable fabric pads included
  • Comes with a quarter-inch adapter and a 4-pin XLR adapter for use with portable or desktop devices

Product Considerations

  • The stock cable is 3 meters long, which is too long for desktop use
  • Headband adjustment can be a little stiff to move
  • With leather pads, the highs can get slightly sharp
  • There is a slight sharpness in the upper treble that might pose a problem for some listeners, using fabric pads can mitigate this
  • Weight distribution could be better, there's not enough padding on the headband, and the clamp force is low, this distributes all the weight across the top of the head, which can be bothersome after 40-50 minutes

Comparisons (according to reviewers)

  • Vs HiFiMan Susvara: Has a similar driver structure
  • Vs HiFiMan HE1000 Unveiled: Is close in terms of technical performance like resolution, transient response, soundstage, depth, and openness
  • Vs HiFiMan Arya Stealth: Has a better build quality and bass response

Takeaway: The FiiO FT7 is a well-built, comfortable headphone that offers a neutral-leaning-warm sound that can be tailored with different earpads. The FT7 competes with other headphones that cost significantly more, making it a great pick at its price point.

Product Strengths

  • Plentiful and excellent quality accessories including two carry cases, a wide variety of ear tips, and adjustable filter tips to change the sound signature

  • The shell is metallic and on the larger side, which might affect the fit for some users
  • Sound isolation is below average due to the vents on each earpiece
  • Highs can be a little too much with the wrong source, potentially leading to sibilance

Comparisons (according to reviewers)

  • Vs FiiO FH5: FH7 is a direct upgrade with better balance in bass regions, crisper treble, more detail, larger soundstage and better imaging
  • Vs Campfire Audio Polaris 2: FH7 is more refined and nuanced, with better accuracy and micro-detail retrieval
  • Vs Fearless Audio S8Z: FH7 provides more warmth and enhanced low end, whereas S8Z is more revealing and transparent
  • Vs Final Audio B3: Both offer similar tonality towards neutral clarity, but the FH7 feels like a B3 with extra fun

Product Strengths

  • Detailed and clean sound, putting plenty of micro-details on the foreground
  • Good build quality and comfortable design
  • Swappable audio plugs included
  • Tuning switches featured
  • Open and wide soundstage

Product Considerations

  • The FH5s gives a harder edge to treble notes, but at the same time creates a wider and more spacious soundstage
  • The FiiO FD5 emphasizes warmth, smoothness, and a lush sound with prominent bass and midrange, where the FH5S has a more textured midrange, and a cleaner bass with less emphasis

Takeaway: The FiiO FH5S provides an outstanding unboxing experience and impressive features, along with a clear sound. The IEM allows for long listening sessions.

Our Summary

Product Strengths

  • Shockingly good for the money, a very well-tuned headphone for the price category
  • Good bass response that is fun, with lots of thumpiness and impact in the lower sub-bass regions, while maintaining a clean mid-bass region
  • Trouble response is fairly target-adherent with a chill character and not overly fatiguing
  • Comes with a banger accessories package providing two cables, a carry case, more than a lot of companies are coming out with
  • Delivers impressive sound quality across the board, backed by excellent build quality and a generous set of accessories

Product Considerations

  • The actual earpad area for the ear is not super great, and it will be felt a little bit on the ear, might be more on-ear than fully over-ear if you have really large ears
  • Sound staging is one area that could improve the most, because there is almost none, can sound almost claustrophobic, because everything is happening right here all the time
  • Mid-range is not all that exciting to listen to, vocals can be shouty or honk-type sound to certain vocalists
  • Build quality feels good for $150, but it would not pass the sniff test for $500, definitely feels like it's a budget device

Comparisons (according to reviewers)

  • The AKG K361 has advantages over the FiiO FT1, like sound staging
  • The FT1’s level of midrange fidelity is impressive, rivaling the best mid-fi headphones such as the Sennheiser HD6XX and the Sundara
  • It outshines most closed-back classics, including the Sony MDR-7506, AKG K361, and beyerdynamic DT700 Pro X
  • The smaller FiiO FT1 was enjoyed even more than the FiiO FT5, since it strikes the right balance between fun, warmth, and technicality, handling tough tracks with much more ease than anticipated

Takeaway: The FiiO FT1 is a surprisingly good closed-back headphone for the money and offers a well-tuned sound signature with good bass response. This headphone is priced at $150 and is surprisingly nice with some great terminations.

  • Package offers great value with a wide selection of ear tips and carry cases
  • Good imaging, fast attack, and nuanced texture

Product Considerations

  • Has a more intimate rather than wide-open soundstage

Comparisons (according to reviewers)

  • Compared to the FH5, the FH5 is more detailed, neutral, and cleaner sounding overall, while the FH3 is more V-shaped and fun to listen to

Takeaway: The FH3 is a great choice if someone wants fun sound and good soundstage in an IEM at a reasonable price. This IEM provides a great listening experience that will not be fatiguing.

Our Summary

Product Strengths

  • Cohesive sound due to single dynamic driver design.
  • Nostalgic design reminiscent of 1940s with beautifully built stainless steel and chrome finish.
  • Comes with a high-quality 8-core silver coated copper cable with swappable plugs (3.5mm, 2.5mm balanced, 4.4mm Pentaconn).
  • Full-bodied and punchy bass, warm and well-defined mids, and smooth, liquid highs.
  • Wide soundstage compared to other IEMs, with instruments rendered with natural timbre and great separation.

Product Considerations

  • Treble can get shouty and harsh at higher volumes, possibly requiring longer burn-in.
  • Stock sound signature is a bass-heavy v-shape, which might veil the mid-range for some listeners.
  • Included tri-flange tips and interchangeable tubes may not significantly change the sound.
  • Semi-open design offers mediocre isolation, making it unsuitable for very noisy environments.

Comparisons (according to reviewers)

  • Vs FD3: FD5 is a little more refined and has sufficient detail for the price, whereas FD3 is a little too veiled.
  • Vs Softears Twilight/Kingfisher: Softears Twilight and Kingfisher completely outperform the FD5 in sheer level of tuning and detail.
  • Vs Letshuoer S12: The S12 tunes better with a bass that is just as strong as the FT5, while not bleeding into the mid-range in any way.
  • Vs SIVGA Nightingale: The Nightingale has a somewhat larger sound with more air, and the imaging is more precise, but the FD5 has a fuller sounding midrange and stronger midbass presence.
  • Vs FiiO FH5S: FD5 is thick, warm, smooth, and lush, the FH5S offers crisper highs, a more textured midrange, and a tighter bass with less fullness.

Takeaway: The FD5 offers a cohesive and nostalgic listening experience. With great build and an included modular cable, this IEM is a good choice for listeners who enjoy a bass-forward sound with musicality.
