Main trade-off
Beats Solo3 Wireless
Charges over Micro-USB, unlike Solo 4.
Head-to-head
Beats Solo3 vs Solo 4: Solo 4 adds USB audio without adding ANC
The short answer
Choose Solo 4 if you want USB-C charging, digital USB audio and the longer playback claim. Consider Solo3 only when the exact older-model offer is attractive and Bluetooth plus passive analog covers your needs. Neither has ANC.
Before you choose
The reasoning and the trade-offs
One-quarter more rated wireless playback
Solo 4’s 50-hour claim is 25% above Solo3’s 40-hour claim.
What this is based on
Beats Solo 4 claims 50 hours of wireless playback and Solo3 claims 40 hours. Neither has ANC. (50 minus 40) divided by 40 times 100 = 25%.

What matters in practice
The differences that matter
One-quarter more rated wireless playback
Solo 4’s 50-hour claim is 25% above Solo3’s 40-hour claim.
How we reached this conclusion
Beats Solo 4 claims 50 hours of wireless playback and Solo3 claims 40 hours. Neither has ANC. (50 minus 40) divided by 40 times 100 = 25%.
USB-C reduces one cable category
Solo 4 can charge and receive digital audio over USB-C, while Solo3 needs Micro-USB to charge and a separate analog path for wired sound.
How we reached this conclusion
USB-C charging plus audio on Solo 4. Micro-USB charging only on Solo3.
The upgrade does not change the ANC answer
Both fail an active-noise-cancellation requirement, even though one is newer.
How we reached this conclusion
ANC is absent on both. Passive analog is present 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.

Meets these checksBluetooth 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, Solo3 Wireless
Solo3 Wireless
A legacy on-ear option that still offers a battery-free cable fallback. Solo 4 makes more sense if you want USB-C charging or digital USB audio, so compare the full package before choosing an older offer.
- Best matched use
- A lower-priced legacy offer with analog backup
Checked facts
- Apple rates playback up to 40 hours.
- Charging uses Micro-USB.
- A compatible RemoteTalk analog cable works when the battery is depleted.
- The on-ear design folds for storage.
Choice B
Beats, Solo 4
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.
- Best matched use
- Folding on-ear listening with both USB and analog cables
Checked facts
- Weight is 217 g.
- Rated up to 50 hours of Bluetooth playback.
- The included USB-C cable supports digital audio and charging.
- The included 3.5 mm cable needs no battery power.
Meaningful differences
What changes the fit
| What changes | Beats Solo3 Wireless | Beats Solo 4 | Why it matters |
|---|---|---|---|
| Charging | Micro-USB | USB-C | Solo 4 avoids carrying a separate older charging cable. |
| Digital USB audio | No | Yes | Solo 4 adds a listening path, not just a different connector. |
| Wireless playback claim | Up to 40 hours | Up to 50 hours | The new claim adds ten hours. |
| Passive analog | Supported with compatible RemoteTalk cable | Supported with included 3.5 mm cable | Both can continue listening after battery depletion. |
| Active noise cancellation | No | No | Upgrading does not add ANC. |
| Form factor | Folding on-ear | Folding on-ear | The broad fit and packing style remains on-ear and folding. |
| Modern spatial feature | Do not assume current head tracking | Personalized Spatial Audio with compatible devices | Check device requirements before treating the feature as part of your setup. |
What you give up
Every choice has a cost
If you choose Beats Solo3 Wireless
- No digital USB audio or active noise cancellation.
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
A low older-model price needs context
Solo3 is a legacy design. Compare a genuine new offer with the current Solo 4 package rather than assuming every low listing has the same condition and accessories. A missing RemoteTalk cable also matters if passive listening is the reason you chose it.
The new cable path is more important than the connector name
USB-C is useful here because it carries audio as well as power. That lets Solo 4 work as a digital wired headphone on a compatible source. Solo3’s Micro-USB port cannot do the equivalent job.
Do not buy either to solve cabin noise with ANC
Both remain non-ANC on-ear headphones. If that is the problem you are trying to solve, moving from Solo3 to Solo 4 changes the wrong part of the specification.
What this comparison cannot tell you
- No claim is made that old inventory has a particular remaining battery health.
- The playback comparison is based on manufacturer maxima, not measured performance.
