What reviewers think

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

Product Strengths

  • Compact build and sleek, premium design with glass and aluminum materials
  • Versatile connectivity with both balanced (2.5mm) and unbalanced (3.5mm) outputs
  • Supports a wide range of Bluetooth codecs, including AAC, SBC, aptX, aptX HD, and LDAC
  • Can be used as both a wireless Bluetooth receiver and a wired USB DAC
  • Has a useful companion app for added control, EQ, and settings adjustments

Product Considerations

  • Glass design could be prone to damage from drops
  • Bluetooth range might be limited for some users
  • The small OLED screen could display more information
  • Android's USB DAC support can be spotty, requiring troubleshooting or a third-party app for optimal performance
  • Some reviewers found the stock sound signature a bit blunted or lacking in dynamics compared to other options

Comparisons (according to reviewers)

  • Vs. iFi Go Blue: The BTR5's build feels more premium but comes with the fear of breaking the glass, sound quality is comparable
  • Vs. Astell&Kern XB10: The XB10 has clearer, more articulate sound but may have hiss with sensitive IEMs and lacks wired DAC capability
  • Vs. Shanling UP4: The UP4 has a more open and articulate sound, while the BTR5 has better app support, harmonics controls, and balance controls
  • Vs. EarMen Eagle: The EarMen Eagle offers better sound quality but lacks the features and versatility of the BTR5
  • Vs. FiiO BTR3: The BTR5 has better power, a more mature sound, and is less smooth and relaxed
  • Vs. FiiO M5 DAP: The BTR5 has better detail, especially in the treble, thanks to its dual DAC chip configuration, FPGA, and crystal clock system

Takeaway: The FiiO BTR5 is a versatile device that combines solid audio performance with convenient features like Bluetooth connectivity and app control, making it a great way to upgrade sound on the go or add wireless capabilities to wired headphones. Its robust build and comprehensive codec support make it a strong contender in its price range.

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.

Topping Audio is a measurement-focused hifi brand that developed its own proprietary PSRM DAC architecture and NFCA amplifier topology to achieve exceptionally low distortion levels. Their products, from the flagship D90 III Discrete DAC to entry-level interfaces like the E2x2, use advanced technologies like custom I/V conversion stages and high-feedback Class B designs to deliver clean, accurate sound reproduction.
Expand Details

Our Summary

Product Strengths

  • Phenomenal sound quality.
  • Very usable and enjoyable interaction due to a physical volume knob.
  • Plenty of power for almost everything and can drive just about anything.
  • Versatile; it can be used as a desktop all-in-one, a Bluetooth portable DAC/amp, a portable amplifier, and even a DAC for speakers.

Product Considerations

  • Susceptible to EMI noises, which can be a deal breaker; static noises, pops, and crackle sounds can occur when a phone is placed directly on top of it.
  • Not a completely balanced architecture; the 3.5mm & 4.4mm headphone outputs sound the same.
  • Charging port may not indicate charging on anything higher than an 18W charging block, and some chargers may not work.

Comparisons (according to reviewers)

  • Vs FIIO BTR-7: Sounds more refined and has more detail and resolution.
  • Vs SMSL C200: The C200 sounds significantly warmer with a fuller, juicier bass line and a little bit more airy, while the G5 is more focused on clean and clear edges, tidy, well-focused—and clean.
  • Vs SMSL M500 MK2: The M500 MK2 sounds overall better with dynamics at the same level as the G5 and fuller, warmer tonality—and a bigger, more spacious soundstage.
  • Vs Moondrop Moonriver 2: The treble is more refined, better details up top, and a sharp edge without being overboard like the Moonriver 2 can.

Takeaway: The G5 is a well-built and versatile portable DAC/amp with a neutral, clean, and dynamic sound. It is great for those looking for an all-in-one solution that can drive almost any headphone or IEM.
