- Light 217 g folding on-ear design
- Fast Fuel claim provides five hours from a 10-minute charge
Reasons to skip it

Short answer: The Beats Solo 4 makes the clearest case for itself through long claimed battery life, low weight, and unusually flexible wired listening. It is less convincing for noisy travel because it does not have active noise cancellation, and the on-ear fit remains something a specification sheet cannot settle.
The Solo 4 is a compact wireless headphone rather than a smaller version of an ANC travel model. Beats lists Bluetooth 5.3, personalized Spatial Audio support, USB-C audio, a 3.5 mm analog input, and up to 50 hours of battery life. That combination is useful for people who move between a phone, laptop, and occasional wired source.

Beats Solo 4 key specifications
| Specification | Published detail |
|---|---|
| Wearing style | On-ear, foldable wireless headphones |
| Weight | 217 g / 7.65 oz |
| Bluetooth | Version 5.3 |
| Battery claim | Up to 50 hours |
| Fast charging claim | 10 minutes for up to 5 hours |
| Wired audio | USB-C and 3.5 mm |
| Active noise cancellation | No |
| Charging connector | USB-C |
| Android support | Google Fast Pair and Find My Device |
| Apple support | One-touch pairing, Find My, and personalized Spatial Audio |
The most important line is not the battery claim. It is the combination of on-ear fit and no ANC. Those two details determine whether Solo 4 suits a quiet desk, commute, or flight more than any color choice does.
Battery life is the headline advantage
Beats publishes a maximum of 50 hours of listening time. Real runtime will vary with volume, call use, connection conditions, and enabled processing, so the number should be treated as a ceiling rather than a guarantee. Even so, the published figure is high enough to make frequent charging less central to the buying decision.
Fast Fuel is also useful on paper: Beats says a 10-minute charge can provide up to five hours of playback. That can matter more than the maximum runtime when a headphone is found empty shortly before a call or trip.
USB-C is used for charging and can also carry digital audio. The included 3.5 mm input provides another fallback and does not require battery power. That is a meaningful distinction from wireless-only budget headphones.
Wired listening has two different modes
Solo 4 supports lossless audio over USB-C when connected to a compatible source. Beats notes that some wireless features are unavailable while using USB-C audio, so this is not simply Bluetooth with a cable attached.
The 3.5 mm input is more universal. It can connect to an airplane adapter, older computer, controller, or audio interface with a headphone output. It also works without battery power. Buyers should still verify whether their phone or tablet needs an adapter.
“Lossless” describes the digital connection, not an automatic promise that every listener will prefer the sound. Source material, volume, fit, EQ, and personal preference remain important.
Sound claims need a listening test
Beats describes custom 40 mm transducers and an updated acoustic architecture. Those details tell us how the product is positioned, but they do not establish bass accuracy, vocal balance, treble smoothness, imaging, or distortion.
We therefore do not assign a sound score. A useful pre-purchase check is whether the buyer values Beats ecosystem features and wired flexibility more than codec lists or measured neutrality. Anyone buying for mixing, mastering, or analytical listening should consult independent measurements and compare purpose-built studio headphones.
On-ear comfort is the biggest uncertainty
At 217 g, Solo 4 is relatively light and folds for storage. Low weight can reduce pressure on the head, but on-ear pads rest directly on the ears instead of surrounding them. Comfort depends on ear shape, clamp, glasses, temperature, and session length.
This makes the return policy important. A five-minute try-on cannot reliably answer whether the pads remain comfortable through a full work session. Our office headset comfort guide explains why fit geometry matters as much as headline weight.
Calls, controls, and device support
Beats lists beam-forming microphones and a voice-targeting algorithm for calls. That confirms the intended use, not performance in wind, traffic, or a shared office. A dedicated boom microphone remains the safer choice when speech intelligibility is business-critical.
The headphone supports Apple and Android convenience features. Apple users get one-touch pairing, Find My, and hands-free Siri. Android users get Fast Pair, Find My Device, and access to the Beats app. Physical controls handle music, calls, and voice assistants without relying entirely on touch gestures.
Noise control and commuting
Solo 4 does not have active noise cancellation or a transparency mode. The on-ear pads may reduce some outside sound, but passive isolation depends on fit and should not be assumed to match a sealed over-ear ANC headphone.
For a quiet home, library, or casual walk, that may be acceptable. For aircraft cabins, trains, and loud offices, effective ANC can reduce the temptation to raise volume. Buyers focused on travel should compare ANC models before paying a premium for Solo 4 styling.
Who should buy the Beats Solo 4?
Solo 4 is most plausible for:
- Buyers who want long battery life and a folding design.
- People who alternate between Bluetooth, USB-C audio, and 3.5 mm sources.
- Apple or Android users who value quick ecosystem pairing.
- Listeners using headphones mainly in moderate or quiet environments.
- Travelers who prioritize compact size over active noise cancellation.
Consider another model if you:
- Need ANC for flights or a noisy commute.
- Strongly prefer over-ear pads.
- Need a verified broadcast-quality microphone.
- Want a neutral studio-monitoring tool.
- Expect every wireless feature to remain available over USB-C audio.
Frequently asked questions
Does Beats Solo 4 have noise cancelling?
No. Beats does not list active noise cancellation for Solo 4.
Can Solo 4 work with a 3.5 mm cable?
Yes. Beats lists a 3.5 mm analog input, and analog listening can work without battery power.
Can it play audio over USB-C?
Yes, with a compatible USB-C source. Beats also advertises lossless USB-C audio, while noting that some wireless features are unavailable in this mode.
Is Solo 4 an over-ear headphone?
No. It is an on-ear design, so the pads sit on the ears rather than around them.
Final verdict
The Beats Solo 4 has a coherent feature set: long claimed battery life, low weight, folding cups, and two useful wired modes. Those strengths make it more adaptable than many wireless-only on-ear headphones.
Its limitations are equally clear. There is no ANC, comfort is personal, and specification sheets cannot prove sound or call quality. If those constraints fit your routine, Solo 4 belongs on the shortlist; if noise control is the priority, start with a different category.
