Beats Solo

About Beats Solo

Beats Solo is the on-ear line, and on-ear is a different category from over-ear rather than a cheaper version of it. The pads sit on your ears instead of enclosing them, which makes the headphones lighter, cooler, smaller in a bag and much longer-lasting on a charge, and which also means they block less of the room and press on the ear itself. The current model is the Solo 4, announced in April 2024 as the first redesign of the line in seven years. It carries no active noise cancelling at all, which is the fact that decides most of the buying arguments below. What the line does hold is the longest quoted battery life of any Beats headphone and the lowest weight, and for a large number of people that is the right pair of strengths.

On-ear or over-ear, and how to decide

Decide on wear time rather than on price, because that is what the difference actually turns on.

Under an hour at a stretch, on-ear usually wins. It is lighter on the head, cooler, quicker to put on and take off, and less bulky to carry. The lower isolation matters less on a short journey or in a reasonably quiet room.

Past two hours, over-ear usually wins. On-ear pads press on the ear itself, and that pressure builds in a way an over-ear pad resting on the skull does not.

Isolation splits the same way. Over-ear encloses and blocks more before any electronics are involved. On-ear leaves more of the room audible, which is a drawback on a train and an advantage in an office where you want to hear somebody approach.

There is no better answer here, only a better match for how you listen.

What Beats states about the current Solo

For the Solo 4, Beats quotes up to 50 hours of listening on a single charge, and a 10 minute charge for up to 5 hours of playback. The drivers are custom 40 mm transducers. The headphones weigh 217 g, which is light for the category.

There are two wired inputs, and both matter. A 3.5 mm analogue socket takes an ordinary cable, which is still the practical answer on an aircraft entertainment system. A USB-C input carries digital audio through a built-in digital to analogue converter, including lossless playback, so the same cable that charges the headphones can feed them.

Beats lists personalised spatial audio with head tracking, one-touch pairing and automatic pre-pairing across your devices on both iOS and Android, Find My on Apple hardware and Find My Device on Android, audio sharing, and Hey Siri.

Noise cancelling is not on that list. Beats describes the on-ear cushions as providing passive isolation, and that is all the line offers.

What independent testing found

Battery life is the part that survives contact with a reviewer. TechGearLab measured 73 hours, well beyond the 50 hours Beats quotes, and rated the line one of the lightest it had tested at 218 g on its own scales. Macworld could not run the claim to exhaustion but judged 50 hours reasonable. Call quality also tested better than expected, scoring 6.9 out of 10 at TechGearLab, which noted that voices stayed clear against background noise.

Sound was the weaker result. TechGearLab scored audio quality 4.3 out of 10, describing punchy lows and pleasant mids that lack detail and dimension next to rivals. Macworld called the sound good for the price rather than great, and pointed at a general lack of crispness and at bass without much definition.

Both reviews landed on the same value judgement. At the 199.99 US dollar list price the line is hard to argue for. Macworld put it plainly, calling the headphones inoffensive at list price and a steal at 150 dollars or less.

The comfort ceiling

The most useful number in either review is the one about how long you can wear these. TechGearLab scored comfort 1.5 out of 10, its lowest rating for the product, describing them as surprisingly comfortable for the first hour and sore afterwards, with clamping force that holds wear time under about two hours. Macworld found the headband does not contract far enough for smaller heads and that spring tension builds pressure over a long session, particularly for anyone wearing glasses.

That is not a defect so much as the shape doing what the shape does. It does mean the battery life and the wear time point in opposite directions. A pair that runs for 50 hours and gets uncomfortable at 90 minutes is a pair you charge once a month and use in short bursts, which is a perfectly reasonable way to own headphones as long as it is the way you were planning to.

What to weigh against the nearest rivals

The closest comparison is inside the Beats range rather than outside it. Macworld recommended the Studio Pro instead, on the grounds that a modest step up in price buys active noise cancelling, an over-ear fit and better sound. That is the trade to think hardest about, and it costs you battery life and about 50 g.

On-ear headphones are a thin category now, so most of the outside competition is not on-ear at all. TechGearLab pointed buyers at over-ear models and at wireless earbuds for better value at the price, naming the 1More SonoFlow Pro and the Tozo HT3 as cheaper alternatives that do more.

What Solo keeps against all of them is the combination of weight, folding size and runtime. If your headphones live in a bag and come out for 40 minutes at a time, that combination is worth more than a specification sheet suggests.

Who should buy something else

Anyone who wears headphones for hours at a stretch. Two independent reviews put the comfortable limit at roughly one to two hours. Over-ear is the shape built for long sessions, whether that is the Studio Pro or a rival.

Anyone who needs real isolation. There is no active noise cancelling in this line at all, and on-ear pads cannot enclose the ear. A noisy commute or an open-plan office is the wrong setting for it.

Anyone who wears glasses. The clamping force and the arm of a frame work against each other, and both reviews raised it.

Anyone buying primarily on sound quality. This is where the line scored worst in testing, and at list price the money buys better elsewhere.

Anyone buying for exercise. On-ear pads slide once you start moving, and ear-hook or wingtip earbuds are the answer.

Anyone paying full list price without a reason to. Both reviews said the same thing in different words: this is a sensible purchase on discount and a hard one at 199.99 dollars.
