Few headphone lines have a reputation as instantly recognizable as Beats. The Solo name has been around for well over a decade, and the Solo 4 keeps the formula that made it famous, a light on-ear design, a bass-forward sound, and a price that sits above the bargain shelf. This particular listing is the renewed version in Cloud Pink, which means Amazon has inspected and repackaged a used unit. I spent two weeks with these headphones to find out how much the Solo 4 deliver, and what a renewed purchase really gets you.
This review contains affiliate links. If you buy through them, the site earns a commission at no extra cost to you, and that never changes my verdict. The unit I tested was a renewed model in the Cloud Pink finish, so every impression below reflects the product as it is actually sold.
The Solo 4 are not the premium flagship of the Beats range, that title belongs to the Studio line. They are the everyday pair, aimed at commuters and students who want the brand look with solid battery life and simple pairing. The headline numbers are a 50-hour battery, one-touch pairing on both Apple and Android, and a lightweight frame that disappears on your head.
Design and Build
The Solo 4 are unmistakably on-ear headphones, which means the cushions sit on top of your ears rather than around them. That design choice keeps the headset small and light, around 217 grams, and it folds flat for travel. The Cloud Pink finish is soft and matte, and it resists fingerprints far better than the glossy finishes of older Solo models. The plastic frame feels solid for the weight, and the folding hinges are tight with no wobble.
The earcups are held by an adjustable headband with a cushioned underside, and the fit is snug by design. On-ear headphones rely on a firm seal to sound right, and the Solo 4 press a little harder than an over-ear pair would. They are comfortable for a couple of hours, but the clamping force becomes noticeable on longer listening sessions, which is a trade-off inherent to the on-ear form factor rather than a defect in this specific pair.
Physical controls live on the left earcup. There is a multi-function button for play, pause, track skip, and calls, plus a rocker for volume. The controls are firm and easy to find without looking, and the USB-C port on the bottom handles both charging and wired listening when the battery is empty. A 3.5mm jack is included for older sources, and the headphones support both class 1 Bluetooth and USB-C audio.
Key Features
The 50-hour battery is the headline feature, and it is not marketing fluff. I charged the Solo 4 once at the start of testing and used them daily for two weeks, with a couple of hours of listening and calls a day, and the battery never fell below half. Even with heavier use you will not charge these weekly. There is also a Fast Fuel system that gives around three hours of playback from a five-minute charge, which makes a forgotten charge a non-event.
Pairing is where the Solo 4 excel. On Apple devices they use the same one-touch pop-up pairing as AirPods, with automatic switching between an iPhone, iPad, and Mac. On Android, the Beats app provides pairing, firmware updates, and a fully customizable button. This cross-platform friendliness is genuinely rare, because most headphone brands favor one ecosystem over the other, and the Solo 4 treat both sides equally.
Sound delivery uses Beats custom acoustic architecture, which is a fancy way of saying the Solo 4 are tuned for a punchy, musical response with a strong low end. They are not flat reference headphones, and they are not trying to be. There is support for spatial audio on Apple devices, which gives a wider, more immersive stage in movies and compatible music, and the effect is tasteful rather than gimmicky.
Real-World Performance
The sound signature is what Beats buyers expect. Bass is prominent and energetic, and the Solo 4 handle hip-hop, pop, and electronic music with enthusiasm. The midrange is clear enough for vocals to sit forward, and the treble is controlled without being harsh. They are not the last word in detail, and Classical or jazz listeners may find the tuning too colored, but for everyday pop, rock, and podcast listening they sound great.
Noise isolation is passive, because the Solo 4 have no active Noise Cancelling. The on-ear seal blocks a fair amount of background noise, and on a commute the rumble of a bus is reduced to a murmur. They do not silence an office the way ANC Headphones would, so if you need complete quiet, look elsewhere. That is the biggest single gap in the feature set, and it is worth being honest about before you buy.
The microphone is good enough for calls. Voices come through clearly in quiet rooms, and callers could understand me even on a busy street, though the wind performance is average. On a laptop for video meetings the Solo 4 work reliably over Bluetooth, and the USB-C wired mode is a useful fallback when Bluetooth is flaky on older computers.
The renewed condition deserves a direct mention. The Cloud Pink unit I received looked essentially new, with the original cushions, cable, and charging case in the box, and it performed identically to a fresh pair. Renewed products come with Amazon 90-day support, which is more protection than many third-party refurbs offer. The only risk is cosmetic wear, because no two renewed units are identical, so inspect the listing photos and reviews before buying.

How It Compares
The Solo 4 compete most directly with other wireless on-ear and entry over-ear models in the same price band.
| Feature | Beats Solo 4 | Beats Studio Pro | Sonos Ace |
|---|---|---|---|
| Style | On-ear | Over-ear | Over-ear |
| Active noise cancelling | No | Yes | Yes |
| Battery life | Up to 50 hours | Up to 40 hours | Up to 30 hours |
| Fast charging | 5 min for 3 hours | 10 min for 4 hours | 10 min for 3 hours |
| Platform support | Apple and Android | Apple and Android | Apple and Android |
| Weight | 217 grams | 260 grams | 312 grams |
| Typical price | Mid-range | Premium | Premium |
If noise cancelling matters, the Studio Pro or the Sonos Ace are the better buys, though both cost more and weigh more. The Solo 4 win on battery life, weight, and price, and for someone who wants a light, low-maintenance pair for music and calls, they are the strongest value of the three. The choice comes down to whether quiet matters more to you than lightness and endurance.
Who Should Buy It
Buy the Beats Solo 4 if you are a commuter, student, or traveler who wants a light headphone that lasts all week on one charge and pairs instantly with whatever phone you carry. They are a superb everyday pair for music and calls, and the renewed version makes the price more reasonable while keeping the same performance. If you already live in the Apple ecosystem and want the same effortless pairing as AirPods with a more classic headphone design, these are the natural pick.
Skip them if you need active noise cancelling, if you prefer the pressure-free fit of over-ear cushions, or if you want a neutral reference sound for critical listening. For everyone else, the Solo 4 are a dependable, stylish daily driver, and you can check the current price of the Beats Solo 4 on Amazon.
How We Test
I used the renewed Beats Solo 4 for two weeks as my primary headphone, with daily listening, phone calls, and video meetings. I measured battery life from a single charge over two weeks of mixed use, tested one-touch pairing and auto-switching across an iPhone, iPad, and Android phone, and ran the USB-C wired mode on a laptop. I also compared the sound to the Studio Pro and the Sonos Ace over the same test tracks.
I listened across pop, rock, hip-hop, electronic, and spoken-word content to judge the tuning fairly. For independent context on the wider headphone market, the Wirecutter guide to headphones under $100 is a useful comparison point, and Beats official specifications are listed on the Beats Solo 4 product page.
