Sony WH-CH520 vs JBL Tune 720BT: On-Ear Fit or a Wired Backup?

Choose Sony WH-CH520 if you prefer on-ear pads and only need Bluetooth listening. Choose JBL Tune 720BT if you prefer over-ear cups or want an included audio cable that keeps music playing when the headphone battery is flat. The cable backup requires a compatible audio output; the earcup labels alone do not tell you which will feel better.

The buying question

Is an on-ear Bluetooth-only design right for you, or do you need over-ear headphones with an analog listening backup?

Sony offers an on-ear swivel design but depends on powered Bluetooth listening; JBL offers an over-ear folding design and a separate audio-cable fallback.

Quick verdict

Choose JBL Tune 720BT if

  • You need an analog listening option, including when the headphone battery runs out.
  • You prefer an over-ear folding format.

When to skip: Skip Sony if wired listening is a requirement. Skip JBL if you specifically want pads that rest on the ear instead of an over-ear format.
When the recommendation changes
  • A required analog connection settles the choice in JBL’s favor, even if Sony’s fit appeals to you.
  • If you never use wired audio, your own preference for on-ear or over-ear fit should carry more weight.

The differences that matter

Earcup Format And Carrying

Sony WH-CH520

On-ear headphones with an adjustable headband and swiveling earcups.[1, 3]

JBL Tune 720BT

Over-ear headphones with a foldable design.[4, 5]

What this changes: Choose Sony if you prefer pads resting on your ears; choose JBL if you prefer an over-ear format. For carrying, compare Sony’s swivel arrangement with JBL’s folding arrangement in your own bag. Neither format guarantees better comfort or noise isolation.[1, 3, 4, 5]

The better fit depends on your priorities

Wired Fallback And Power Dependence

Sony WH-CH520

Bluetooth listening without an analog audio input or passive operation. The USB-C connection is for charging.[2, 3]

JBL Tune 720BT

Bluetooth listening plus an included detachable audio cable. JBL explicitly supports cable listening when the headphone battery is flat.[4, 5, 6]

What this changes: JBL is the choice when an analog source or a depleted-battery listening backup matters. That backup requires carrying the audio cable and having a compatible audio output. Sony fits a Bluetooth-only routine where you keep the headphones charged.[2, 3, 4, 5, 6]

Best for your routine

Bluetooth-only listening with an on-ear preference

Best fit: Sony WH-CH520

Based on listed features, not comparative testing.

Sony’s on-ear and swivel arrangement matches that preference. Accept that listening depends on headphone power and Bluetooth rather than a backup audio cable.

Listening from a device with an analog headphone output

Best fit: JBL Tune 720BT

Based on listed features, not comparative testing.

JBL supplies the detachable audio cable and documents wired listening. Verify the source’s connector before relying on it.

Keeping a listening fallback for an empty headphone battery

Best fit: JBL Tune 720BT

Based on listed features, not comparative testing.

JBL explicitly supports using its audio cable with a flat battery. Remember the cable and compatible source; this is not a claim about how long either battery lasts.

Value and trade-offs

One or both observed offers have eligibility conditions, so no unrestricted price difference is shown.

If JBL costs more, its audio-cable fallback or your preference for over-ear cups should justify the difference. If wired listening is irrelevant, prioritize the fit you want rather than paying for nominal battery-hour claims.

There is not enough verified price history here to make a purchase-timing recommendation.

Limitations

  • This comparison covers Sony WHCH520/L Blue and JBLT720BTBLUAM Blue. It does not establish a sound-quality, comfort, isolation or real-world battery-life winner.
  • JBL’s cable fallback establishes listening, not identical microphone, app or button behavior in wired mode. Check those functions separately if they are essential.
  • No packed-size advantage is claimed for swivel versus folding; check the fit in your own bag.

Questions shoppers ask

Can I use Sony’s USB-C cable as a wired listening backup?

No. Sony identifies USB-C as the charging connection and lists no audio input or passive operation. Its guide says starting a charge turns the headphones off automatically.

What should I check before relying on JBL’s cable backup?

Carry its detachable audio cable, not just the USB-C charging cable, and verify that your source has a compatible analog output. A phone without that output needs a compatible audio adapter. The flat-battery claim concerns listening; do not assume it also provides all wireless call and app functions.

Methodology and sources

We checked manufacturer model information, Sony’s input and passive-operation specifications, fit illustrations, and JBL’s separate audio and charging cable instructions.
