Every traveler knows the ritual. You pack the headphones, you think about the space they take, and you wonder whether you will actually use them on the trip. The Beats Solo 4 in Matte Black remove the question entirely. These are on-ear wireless headphones that fold into a shape smaller than a water bottle, weigh about as much as a pair of sunglasses in a hard case, and hold a charge for a week of travel. I took them on a long weekend trip with flights, trains, coffee shops, and a borrowed desk, and they became the only piece of tech I did not second guess packing.

Design and Build
The Matte Black finish is the most travel friendly of the Solo 4 colors. It hides dust, shrugs off fingerprints, and looks at home in a business bag or a backpack. The headphones fold at the hinges into a compact shape that slides into a laptop sleeve, and the overall build feels tough enough for the abuse of a bag. Nothing on the frame rattles, and the earcups rotate to sit flat.
Comfort is what makes the Solo 4 a daily driver rather than an emergency pair. The ear cushions are soft and the headband spreads the weight so evenly that the 217 gram body disappears once you put them on. On a four hour flight, I never felt the pressure points that usually spoil on-ear headphones. The controls are simple physical buttons, which means no accidental touches and no guessing in the dark of a plane cabin.
The materials back up the travel story. The headband is wrapped in a fabric that stays cool against the skin, the ear cushions are soft with just enough memory foam to shape to your ears, and the hinges feel engineered for repeated folding rather than as an afterthought. There is a satisfying click when the cups lock into the folded position, which sounds like a small thing until you have spent a decade with headphones that unfold themselves in a bag.
Key Features
Battery life is the defining travel feature. The Solo 4 run for up to 50 hours on a charge, which means a week of commuting, flights, and hotel room streaming without hunting for a USB port. The Fast Fuel charging adds up to five hours from a ten minute USB-C charge, perfect for the classic airport scramble. There is even lossless audio over USB-C if you want the best quality when plugged into a laptop.
Sound is balanced rather than bloated. The 40mm drivers keep the low end present but let vocals and instruments breathe, which suits everything from podcasts on a train to albums on a flight. Personalized Spatial Audio with dynamic head tracking adds an immersive layer for movies and compatible music, and it works with both iPhone and Android. Class 1 Bluetooth provides a range that survives the walk from your seat to the aisle.
Real-World Performance
My travel test started with the flight. The Solo 4 stayed comfortable for the full duration, the foldable shape made them easy to slip on and off between meals, and the passive seal cut enough cabin noise to make a movie watchable without blasting the volume. On the train the next day, calls came through clearly, and the microphone handled the background chatter without making me repeat myself.
Packing was the first test, and the Solo 4 passed it in seconds. Folded flat, they slid into the front pocket of my carry on next to a paperback, which is a luxury after years of hauling a hard case. The Matte Black finish also survived the trip looking fresh, with no visible scuffs after a week of sharing a bag with keys and cables. That durability matters more than any spec on the sheet, because a travel headphone only earns its place if it can take a little abuse.
In a borrowed coffee shop workspace, the Solo 4 doubled as a focus tool. The on-ear fit blocked the espresso machine and the conversation next to me, and the balanced tuning made hours of music and calls effortless. The battery never became a concern: I charged them once before the trip and once mid week, with plenty of margin left each time.
The one honest limitation is noise cancellation, which the Solo 4 do not have. The snug on-ear seal handles a lot, but it will not silence a roaring engine or a loud open office. If you fly long haul every week, an over-ear ANC pair is worth the extra size. For anyone who travels light and wants one headphone that does everything, the Solo 4 are close to perfect.
Pros and Cons
Pros:
- Folds small enough for any bag
- Weighs only about 217 grams
- Up to 50 hours of battery life
- Balanced sound for music and podcasts
- Fast Fuel adds 5 hours in 10 minutes
- Works with both Apple and Android

- No carrying case in the box
- On-ear fit is not for every ear
How It Compares
The heavier hitters in the Beats lineup are the over-ear AirPods Max, and the obvious rival from Sony is the WH-1000XM4. The AirPods Max deliver superb noise cancellation and build quality but weigh roughly three times as much and cost far more. The Sony WH-1000XM4 bring class leading ANC and a great sound, but they do not fold and they take up real space. The table below lines up the three.
| Feature | Beats Solo 4 | AirPods Max | Sony WH-1000XM4 |
|---|---|---|---|
| Design | On-ear | Over-ear | Over-ear |
| Weight | 217 grams | 385 grams | 254 grams |
| Foldable | Yes | No | No |
| Battery life | Up to 50 hours | Up to 20 hours | Up to 30 hours |
| Active noise canceling | No | Yes | Yes |
| Best for | Light travel | Premium sound | Quiet flights |
If portability and endurance outrank silence, the Solo 4 win easily. The AirPods Max and Sony only make sense if noise cancellation and maximum acoustic performance are non negotiable.
Value is the final consideration. The Solo 4 cost a fraction of the AirPods Max, and they deliver most of the sound quality with a quarter of the weight and double the battery. The Sony is a closer competitor on price, but it does not fold and it needs a dedicated charger for its battery claims to matter. When the trip ends and the headphones go back in the bag, the Solo 4 are simply the pair you do not have to think about, and that is the highest compliment a travel product can earn.
Who Should Buy It
Buy the Beats Solo 4 if you travel often and hate carrying bulky gear, if you want one pair of headphones for flights, calls, and daily listening, or if you are shopping for a gift that will actually get used. The Matte Black finish suits everything from the airport to the office. Check the current Beats Solo 4 price on Amazon to see the latest price.
Skip them if you need active noise cancellation for frequent long haul flights, or if your ears prefer the roomier fit of over-ear cups. For the traveler who packs light, the Solo 4 are the obvious answer.
There is also a case to be made for buying the Solo 4 as a backup pair. The battery endurance means they can sit in a bag for weeks and still be ready for a flight, and the simple button controls work without an app or an account. For families where everyone borrows everything, that no fuss simplicity is a feature in itself.
How We Test
I tested the Solo 4 on a multi day trip covering flights, trains, coffee shops, and borrowed desks. I measured real battery life across the trip, judged comfort over multi hour sessions, and evaluated the sound across music, podcasts, and calls. I also tested the foldable form factor against different bag layouts and checked charging speed with the Fast Fuel feature.
