Sony WH-CH520 vs Beats Solo 4: Only Solo 4 adds a flat-battery cable backup

The short answer

About this comparison

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

Start with what you need it to do

  • I listen wirelessly in quiet places

    Sony’s lower weight is useful when the extra cable paths are unnecessary.

  • I plug into an airplane seat

    Solo 4 provides analog input. Sony requires a separate Bluetooth transmitter rather than a direct cable.

  • I want USB-C music from my laptop

    Solo 4 supports digital USB playback, not only USB charging.

What matters in practice

The differences that matter

Sony is nearly one-third lighter

CH520 weighs 32.3% less than Solo 4.

How we reached this conclusion

(217 − 147) ÷ 217 × 100 = 32.3%.

Solo 4 buys two extra listening paths

The Beats adds digital USB and passive analog to Bluetooth, compared with Bluetooth only on Sony.

How we reached this conclusion

Confirmed paths: Sony one. Beats three. Charging is excluded.

Battery time is not the tie-breaker

Both quote 50 hours, and neither spends that runtime running ANC.

How we reached this conclusion

50 − 50 = 0 rated hours. ANC is absent on both.

Check your own setup

Which headphones work with the way you listen?

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.

Sony WH-CH520

Meets these checks

Bluetooth listening.

Beats Solo 4

Meets these checks

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.

Choice A

Beats, Solo 4

Solo 4

What you give up

Every choice has a cost

If you choose Sony WH-CH520

  • No active noise cancellation, so it does not meet the travel-noise tag.

If you choose Beats Solo 4

  • On-ear pads sit on the ear, so a low weight does not guarantee your preferred fit.

What matters in practice

How to make the call

01

The cheap cable test is decisive

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.

02

Do not confuse a sealed pad with ANC

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.

03

On-ear comfort deserves a real try

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.

Check these before buying

  • Check that your USB-C device supports audio output before buying Solo 4 for wired use.
  • Try the on-ear fit and check the seller’s return terms.

What this comparison cannot tell you

  • The weight difference does not establish better comfort for every wearer.
  • The two 50-hour figures are manufacturer maximum claims, not equal measured runtimes.
