Sony WH-CH520 vs FiiO DAC
Quick Verdict
The Sony WH-CH520 is the pick for anyone who wants a complete wireless on-ear headphone with up to 50 hours of battery life, multipoint pairing, and app-based EQ. It is a self-contained solution for everyday music and media. The FiiO DAC suits listeners who already own wired headphones and want to improve sound with dual CS43131 chips, balanced 4.4mm output, and a 10-band PEQ. It has no Bluetooth, no battery life rating, and no microphone. Choose Sony for wireless convenience, long battery, and simplicity. Choose FiiO for wired audio refinement and console support. Neither provides active noise cancelling. Check the detailed specifications before you commit, especially the missing codecs and weight.

Sound Quality
Both products earn 24 out of 30 for sound quality, but they achieve that score in different ways. The Sony WH-CH520 is an on-ear wireless headphone, and its driver size is not published in the listing. The FiiO DAC is a portable headphone amplifier and DAC with dual CS43131 chips, supporting PCM 384kHz/32-bit and DSD256, with Hi-Res certification. This means the FiiO can decode high-resolution audio files, but its final sound quality depends on the wired headphones you connect.
The Sony includes DSEE compressed music enhancement, which the listing says improves the quality of compressed audio. It also works with the Sony Headphones Connect app for EQ Custom, but the number of bands is not specified. The FiiO offers a 10-band parametric EQ through its Control App or web interface, with three user presets for detailed tuning. For pure audio hardware, the FiiO has more transparent specifications; for a simple out-of-box wireless sound, the Sony is adequate but lacks detailed driver information.
Comfort and Fit
Comfort is straightforward for the Sony WH-CH520: it is an on-ear headphone, so it sits on your ears. The listing does not publish its weight, but the product description calls it lightweight. A lightweight on-ear design can be comfortable for short sessions, but on-ear pressure varies by user. The FiiO DAC is not worn on the head; its comfort score of 15 out of 20 refers to handling and portability, not wearing comfort.
The FiiO DAC's weight is also not published, so you cannot compare pocket comfort directly. Its wood housing may add some heft, but the listing does not state dimensions. If you need a device that rests on your head for hours, only the Sony qualifies. If you plan to hold or carry a small DAC/amp, the FiiO is the option, but weight remains an open question.
Noise Control and Features
Neither product offers active noise cancelling. The Sony WH-CH520 explicitly lists 'No active noise cancelling' as a con. The FiiO DAC is not a headphone, so noise cancelling is not applicable, and its listing does not publish any noise isolation. Therefore, if you need to block ambient noise, neither option will satisfy you; both rely on the outside environment.
Feature sets differ greatly. The Sony includes multipoint connection for two devices, Google Fast Pair, Find My Device, and the Sony Headphones Connect app with EQ Custom. The FiiO includes a 10-band PEQ, three user presets, button customization, fast or slow volume ramping, auto-sleep, and an RGB sample rate indicator. The FiiO also has a UAC 1.0 and 2.0 toggle for PS5 and Switch support. The Sony focuses on wireless convenience features; the FiiO focuses on wired audio control.
Battery, Bluetooth and Connectivity
Battery life is a clear win for the Sony WH-CH520, with up to 50 hours on a charge. The listing mentions quick charging but does not specify the exact time. It charges via USB Type-C. The FiiO DAC does not publish battery life at all, and the listing suggests it draws power from a USB host, so it may depend on your phone, computer, or console for power. If you need a self-powered portable audio device, the Sony is the safer choice.
Connectivity is another major difference. The Sony uses Bluetooth, but the listing does not publish supported codecs. It includes multipoint for two simultaneous connections. The FiiO is wired only: it offers 3.5mm single-ended, 4.4mm balanced, and 3.5mm SPDIF coaxial outputs, plus detachable cables for Android, iOS, PC, and Mac. The UAC toggle adds PS5 and Switch support. So the FiiO gives you higher quality wired connections; the Sony gives you wireless freedom.
Build, Design and Portability
The Sony WH-CH520 comes in six color options, which is good for personal expression, but the listing does not describe the materials or weight. It is an on-ear design that likely folds or is compact, but that is not confirmed. There is no water resistance rating. The FiiO DAC stands out with a solid walnut or maple wood housing with CNC carving and an oil finish, which suggests a premium build. Its weight is not published, so pocket portability is unclear.
Neither product lists water resistance, so keep both away from moisture. The FiiO includes detachable cables, which can make packing easier, but no case is mentioned. The Sony includes only a USB Type-C cable for charging, with no wired audio option mentioned. For build quality, the FiiO's wood housing is a distinctive feature, while the Sony remains a more typical plastic on-ear headphone, though the listing does not confirm materials.
Call Quality and Daily Use
The Sony WH-CH520 listing does not state microphone specifications or call quality. It is a wireless headphone, so it likely has a built-in microphone, but the listing does not confirm. The FiiO DAC has no microphone and is not designed for calls; it is purely a DAC and amplifier for wired headphones. For daily phone calls, only the Sony could serve, but its call performance cannot be evaluated from the listing.
For daily music and media, the Sony works as a self-contained Bluetooth headphone with long battery and app controls. The FiiO requires you to carry a wired headphone and a USB source, which adds bulk but improves sound quality. Both have apps for control: Sony Headphones Connect and FiiO Control App or web interface. If you want a grab-and-go wireless solution, the Sony is more practical; if you want a desktop or bag companion for wired listening, the FiiO is more capable.
Who Should Buy It
You should consider the Sony WH-CH520 if you want an affordable on-ear wireless headphone with up to 50 hours of battery life. It suits everyday listeners who need multipoint pairing for two devices, app-based EQ, and Google Fast Pair. Avoid it if you need active noise cancelling, a wired audio option, or detailed sound specifications before buying.
You should consider the FiiO DAC if you already own wired headphones and want to improve their sound with a portable DAC and amplifier. It is ideal for listeners who want balanced 4.4mm output, 10-band parametric EQ, and console compatibility. Avoid it if you need Bluetooth wireless streaming, battery independence, or a device with a microphone.
The Deciding Question
The deciding question is simple: do you need a complete wireless headphone or a separate wired DAC and amplifier? If you want to put on a pair of headphones and stream music from your phone with up to 50 hours of battery, the Sony WH-CH520 is the direct answer. If you already have good wired headphones and want to drive them with better electronics, the FiiO DAC is the tool.
Also ask yourself about power and connectivity. The Sony has a specified battery and Bluetooth, but codecs are unknown. The FiiO has no battery life listed and no Bluetooth, but it offers superior wired outputs and EQ control. If you travel light and need wireless, choose Sony. If you sit at a desk or game console with wired headphones, choose FiiO.
Who Should Buy Which
Choose the Sony WH-CH520 if you want a budget on-ear Bluetooth headphone with long battery life, multipoint connection, and the Sony Headphones Connect app. It is best for casual listening, commutes without heavy noise, and users who prefer a trusted brand and simple setup. The lack of ANC and published specs is acceptable if you prioritize battery and convenience.
Choose the FiiO DAC if you are a wired headphone enthusiast who wants to add balanced output, high-resolution decoding, and a 10-band PEQ to your existing gear. It is best for desktop use, portable wired setups with a phone or computer, and console gaming on PS5 or Switch. The missing battery and weight data is less important if you plan to power it from a USB source.
