Beats Solo 4: Comfort, Sound, Battery and Limitations
Beats Solo 4 are worth buying if you want lightweight, on-ear headphones with long battery life, strong everyday sound and Apple or Android-friendly features; they are less appealing if you need active noise cancellation, an open fit or consistently comfortable all-day wear. Their value depends on fit and price: try them on if possible, and compare their fixed on-ear design with over-ear alternatives before deciding.
What the Solo 4 offers
Released in 2024, the Solo 4 is a wireless, on-ear headphone: its ear cushions rest on your ears rather than surrounding them. It builds on the familiar compact Beats Solo format, with updated acoustics, a folding design and connections intended to work with both Apple and Android devices. It is not the same product as the larger Beats Studio Pro, which has over-ear cups and active noise cancellation.
The Solo 4 supports Bluetooth, and it can also play audio through a wired connection. A USB-C cable supports wired audio and charging; a 3.5 mm audio cable is another wired option. Wired listening can be useful when a battery is depleted or when a source lacks Bluetooth, though the right cable and connection depend on the device. The headphones do not have active noise cancellation or a transparency mode, so wired or wireless use does not change their basic isolation limits.
Comfort and fit
At about 217 grams (7.65 ounces), the Solo 4 is light for a headphone, and its foldable frame is easy to pack. The trade-off is the on-ear fit: pressure from the headband and cushions can become noticeable during long sessions, especially for people who wear glasses, have sensitive ears, or prefer roomy over-ear cups. Comfort is individual, so the light weight alone does not guarantee a comfortable fit.
Try to wear them for more than a quick minute before buying, if a store allows it. Pay attention to whether the pads press on your ears, whether the headband feels tight, and whether the fit stays secure when you move. A snug fit helps keep sound consistent, but excessive clamping pressure is a deal-breaker for some listeners. The ear cushions are replaceable, which can help when the original pads wear out, but new cushions will not change the fundamental on-ear shape.
Sound quality and noise isolation
The Solo 4 has a lively, bass-forward Beats sound that suits pop, hip-hop and energetic playlists. Bass is prominent, while vocals and higher-frequency details remain clear enough for casual listening. It is not a neutral reference headphone: listeners who want very even tuning for mixing, or a highly adjustable equalizer, may prefer another model. Your phone’s audio settings and the fit on your head can also affect what you hear.
Passive isolation comes from the ear pads and their contact with your ears; it is not electronic noise cancellation. A good seal can soften some surrounding sound, but voices, traffic and other persistent noise can remain audible. At a busy airport or on public transport, do not expect the quiet that ANC headphones can provide. The lack of ANC also means there is no special mode that amplifies outside sound for conversation; you can take the headphones off or pause playback.
Spatial audio with head tracking is supported on compatible Apple devices and content. It is an optional listening feature, not a requirement for ordinary stereo playback, and its effect varies with the recording and app. Buyers should not choose the Solo 4 solely on the assumption that every song or phone will use head-tracked audio.
Battery life and charging
Beats rates the Solo 4 for up to 50 hours of playback on a charge. That is a manufacturer estimate, not a guarantee for every situation: volume, wireless use, content and other conditions can affect actual runtime. Even so, it is a substantial advantage for travel or daily commuting, where frequent charging is inconvenient. There is no active noise cancellation to switch on, so the battery figure is not dependent on an ANC setting.
Fast Fuel is designed to provide up to five hours of playback after a 10-minute charge. Treat that as a top-line claim under suitable conditions rather than an exact promise. USB-C charging makes it straightforward to use a common cable, but the Solo 4 does not support wireless charging. If the battery is empty, a wired audio connection can still be useful, depending on the source and cable; wired listening is not a substitute for charging if you need wireless features.
Controls, calls and device compatibility
Physical controls on the ear cup handle common tasks such as playback, volume and calls. Buttons are generally easier to operate by touch than small touch-sensitive surfaces, though their placement may take some getting used to. The built-in microphones support calls, but this is not a headset designed to eliminate all background noise: call quality can vary with wind, traffic and the phone or computer in use.
Apple users get features such as one-touch pairing, Find My integration and automatic switching within supported Apple setups. Android users can use the Beats app for supported setup and features, including one-touch pairing and locating functions available through the platform. These conveniences differ by device and operating system, so check the current feature support for your phone before purchase. Core Bluetooth listening works across both ecosystems, but some platform-specific conveniences are not universal.
Limitations and alternatives
The clearest reasons to skip the Solo 4 are its on-ear pressure, lack of ANC and limited suitability for quiet-focused listening. It also does not offer the more extensive sound customization or the same over-ear isolation some buyers want. Its compact folding construction is handy, but people who prioritize immersive isolation or extended comfort may be happier with over-ear headphones.
- Choose the Solo 4 if compact size, long rated battery life, physical controls and cross-platform Bluetooth are your priorities.
- Consider an over-ear ANC model if you regularly fly, commute in loud environments or want less background noise.
- Compare other on-ear headphones if you like the portable format but are unsure about the fit, sound tuning or price.
- Check current prices before buying. A discount can improve the value, while a similarly priced alternative with features you need may be the better deal.
There is no universal “best” choice here: the Solo 4’s battery life and portability are real strengths, but they cannot compensate for uncomfortable pressure or a need for noise cancellation. The most useful buying test is simple: confirm the fit and decide whether passive isolation is enough for the places you will use them.
Frequently Asked Questions
Do Beats Solo 4 have noise cancellation?
No. They rely on passive isolation from the ear cushions and do not include active noise cancellation or a transparency mode.
How long does the Beats Solo 4 battery last?
Beats rates it for up to 50 hours of playback. Actual battery life varies with use and conditions; the company also advertises up to five hours of playback from a 10-minute Fast Fuel charge.
Are Beats Solo 4 comfortable for long periods?
That depends on your ears and head. Their low weight helps, but the on-ear cushions and headband pressure can become uncomfortable during long listening sessions. Trying them on is the best way to judge.
Can I use Beats Solo 4 with Android?
Yes. They connect over Bluetooth, and the Beats app supports compatible Android features. Some Apple-specific conveniences, such as integration with Apple services, are intended for supported Apple devices.
Can Beats Solo 4 play audio when the battery is dead?
They support wired audio, so a suitable cable and source may let you listen without Bluetooth. Check the connection required by your device; wireless functions still require battery power.
Are Beats Solo 4 better than Beats Studio Pro?
They serve different needs. Solo 4 is lighter, folds compactly and has a longer stated battery estimate, while Studio Pro is an over-ear model with active noise cancellation and transparency modes. Choose based on fit, noise control and price rather than assuming one is better for everyone.
