Main trade-off
Sony WH-CH520
No analog input or digital USB playback.
Head-to-head
Choose WH-CH520 for low-weight Bluetooth listening and two-device multipoint. Choose Solo 4 if you need USB audio, an airplane cable or listening with a flat battery. Neither has active noise cancellation.
Before you choose
CH520 weighs 32.3% less than Solo 4.
What this is based on
(217 − 147) ÷ 217 × 100 = 32.3%.
Main trade-off
No analog input or digital USB playback.
Main trade-off
No active noise cancellation or Transparency mode.


Sony WH-CH520 is lighter, while Beats Solo 4 adds USB audio, passive analog and folding. Compare the practical differences behind their 50-hour claims.
Winner by situation
Sony’s lower weight is useful when the extra cable paths are unnecessary.
Solo 4 provides analog input. Sony requires a separate Bluetooth transmitter rather than a direct cable.
Solo 4 supports digital USB playback, not only USB charging.
Neither product includes ANC. Choose a different pair if that is a hard requirement.
What matters in practice
CH520 weighs 32.3% less than Solo 4.
(217 − 147) ÷ 217 × 100 = 32.3%.
The Beats adds digital USB and passive analog to Bluetooth, compared with Bluetooth only on Sony.
Confirmed paths: Sony one. Beats three. Charging is excluded.
Both quote 50 hours, and neither spends that runtime running ANC.
50 − 50 = 0 rated hours. ANC is absent on both.
Check your own setup
Start with the way you listen. USB charging is not the same as USB audio, and some headphones need power even with a cable. These choices are examples until you apply yours.
Bluetooth listening.
Bluetooth listening.
Battery figures are manufacturer claims for the stated mode, not measured travel time. Volume, codec, calls and battery age change runtime. Closed earcups can still leak sound. Weight alone does not predict comfort. USB audio needs a compatible source and cable. This check does not assess sound quality, microphone quality or amplifier power.

Sony, WH-CH520
A light on-ear option for everyday Bluetooth listening and switching between two devices. It is a poor choice if you need an airplane cable or noise cancellation.

Beats, Solo 4
Pick Solo 4 when you want a compact on-ear pair that works wirelessly, by USB-C and through a battery-free analog cable. Choose Studio Pro if noise cancellation is part of the brief.
Meaningful differences
| What changes | Sony WH-CH520 | Beats Solo 4 | Why it matters |
|---|---|---|---|
| Weight | 147 g | 217 g | Sony is 70 g lighter. |
| Wireless playback claim | Up to 50 hours | Up to 50 hours | The shared figure does not distinguish these models. |
| Active noise cancellation | No | No | Neither is an ANC solution for a noisy cabin. |
| Digital USB audio | No | Yes | Solo 4 can listen through its USB-C connection. |
| Analog backup | No analog input | Passive 3.5 mm input | Only Solo 4 can keep playing from a jack after its battery is depleted. |
| Storage | Earcups swivel flat | Folds inward, case included | The packing preference may outweigh the difference in headphone mass. |
| Two-device multipoint | Confirmed | No generic multipoint claim used here | Apple or Android platform features are not counted as universal two-device multipoint. |
What you give up
What matters in practice
List the places you will listen. If one is an airplane jack, a desktop interface or a USB-C laptop without Bluetooth, Solo 4 solves a concrete problem. If every source is already Bluetooth, those extra paths may never be used and the CH520’s lighter frame becomes more relevant.
Both are closed on-ear headphones, but neither actively cancels noise. Their fit can reduce some outside sound without turning either into an ANC travel model. There is no evidence here to quantify that passive isolation.
Both place pads on the ears rather than surrounding them. Sony’s 70 g advantage is measurable, but pad pressure, glasses and head shape determine whether either remains comfortable over a full afternoon.
What the facts say
Useful conclusions from the current headphones comparison, followed by the checked facts used to reach them.
Only 2 of 60 models checked match every need here: “I switch between my laptop and phone”, “I want headphones weighing 250 g or less”, “I want sound through a USB-C cable”, and “I want music when the battery is empty”.
