Beats Solo 4 Review: Did 50 Hours of Battery Actually Hold Up?

I've been testing the Beats Solo 4 for three weeks now, and I have opinions. Strong ones. I went in skeptical — the Solo line has always been more about street cred than substance, and the price tag ($199 at launch, now floating around $169 on Amazon) puts it in direct competition with some serious heavy hitters. After using them as my daily drivers for everything from deadlifts at the gym to eight-hour work sessions to a red-eye flight, here's what I actually think.

That 50-Hour Battery — Is It Real?

Short answer: yes, it's real, and it's frankly ridiculous.

Beats claims 50 hours of playback on a full charge. I charged them once — once — on a Monday morning, and I did not plug them in again until Thursday evening. That's 14 days of on-and-off heavy use: commutes, gym sessions, Zoom calls, late-night YouTube spirals. By the time the low-battery chime finally hit, I had clocked about 46 hours of actual playback and I was actively trying to drain them to test the claim. The remaining 4 hours are probably real if you listen at moderate volumes.

The USB-C fast charging is equally bananas. Five minutes plugged in gets you about three hours of playback. I timed it. I've never owned a pair of headphones where battery anxiety is a completely foreign concept, but the Solo 4 changed that. If battery life is anywhere near your priority list, stop reading and just buy them. This is the bar now.

Wearing Them at the Gym — On-Ear vs Over-Ear Reality Check

This is where things get personal. The Solo 4 are on-ear headphones, not over-ear. That's a distinction that matters a lot at the gym.

On-ear means the pads sit on top of your ears, not around them. For lifting, this is actually a feature, not a bug. Over-ear cans like the Sony XM5 or AirPods Max are bulky, they trap heat, and they slide off when you're lying on a bench doing dumbbell presses. The Solo 4's lightweight 217-gram frame stays put. I did barbell rows, incline press, burpees, and even a few sets of box jumps, and these things did not budge. The clamping force is just right — firm enough to stay anchored, not so tight you feel like your head's in a vise.

The downside? If you have larger ears (I'm average), the pads will press them down after about 90 minutes. For a standard 45-minute gym session, zero issues. For a three-hour marathon session? You'll want to give your ears a break between sets. Also, they're not noise-isolating in the gym sense — the passive seal blocks maybe 60% of gym noise, so you'll still hear the guy grunting on the leg press. I actually prefer this for safety reasons in a public gym, but if you want total isolation, you want over-ear with ANC.

One more thing: sweat. The ear cushions are leatherette and they do get warm after 30 minutes of cardio. A quick wipe-down after and they're fine, but if you're a heavy sweater, consider investing in some aftermarket breathable pads or stick to over-ear workout headphones.

The H1 Chip — Apple Integration Magic

I'm an iPhone user, so the H1 chip experience is genuinely delightful. One-touch pairing is great, but the real win is the ecosystem glue: auto-switching between my iPhone, iPad, and MacBook is seamless. I can start a podcast on my iPhone walking to the train, pick it up on my iPad during the commute, and switch to my MacBook for a call without touching settings. It's the kind of thing that sounds like a minor convenience until you live without it.

"Hey Siri" works reliably, though I'm not a heavy voice-assistant user. The find-my integration is a nice safety net — I've lost AirPods under couch cushions more times than I'd like to admit. With the Solo 4, I can ping them from the Find My app on my phone.

One gripe: if you're an Android user, skip these. You lose the one-touch pairing, auto-switching, and Siri. The experience is still functional via standard Bluetooth, but you're paying a premium for Apple integration you won't use. For Android, the Sony XM5 or the Beats Studio Buds+ make more sense.

Sound Quality — Hip-Hop, Electronic, and the Beats Signature

Let's talk about the elephant in the room. The Beats sound signature has historically been a meme — all bass, no mids, treble that stabs you in the ear. The Solo 4 are better, but they're still Beats.

The bass is punchy and present. If you listen to hip-hop, electronic, or modern pop, these headphones deliver. I tested with Kendrick Lamar's "Not Like Us," Fred again..'s "Marea (We've Lost Dancing)," and Daft Punk's "Giorgio by Moroder." Low-end is thumpy without being muddy. Kick drums hit with authority, and sub-bass elements in electronic tracks have that satisfying physical presence. 808s sound great.

But — and this is a big but — the midrange is recessed. Vocals can feel like they're sitting behind the beat rather than on top of it. Acoustic guitar, jazz, anything with complex mid-frequency instrumentation loses detail. The treble is rolled off enough to avoid fatigue but also robs some air and sparkle from cymbals and high-hats.

For hip-hop and electronic: 8.5/10. For rock, indie, and acoustic: 6/10. For classical and jazz: 4/10. These are not audiophile headphones. They're fun headphones. If you want to feel the drop at the gym or vibe to the beat on your commute, these are excellent. If you're sitting in a quiet room analyzing instrument separation, get the Sennheiser Momentum 4.

Also worth noting: there's no active noise cancellation (ANC). The passive isolation is decent — about as good as any on-ear headphone — but you'll hear your roommate vacuuming or the train screeching. If ANC is a must-have, the AirPods Pro 2 or Sony XM5 are better choices.

Build Quality and Comfort

The Solo 4 feel premium in the hand. The headband is a single piece of flexible, rubberized plastic with a stainless steel internal skeleton. No creaking, no flex wobble. The ear cups swivel flat for storage, which I appreciate. The carrying case is a soft pouch rather than a hard-shell case — fine for tossing in a bag, but I wouldn't trust it in a packed suitcase without some extra protection.

Comfort is a mixed bag. At 217 grams, these are incredibly light — you genuinely forget you're wearing them for the first hour. But the on-ear form factor eventually catches up with you. After about 90 minutes, I started noticing the clamp pressure. After 2 hours, my ears were mildly sore. After 3 hours, I needed a break. This is the trade-off for the portability and gym performance. For short sessions (under an hour), they're more comfortable than any over-ear headphone I've used. For long-haul flights or all-day wear, give me the AirPods Max or Sony XM5.

The controls are physical buttons, not touch surfaces. Thank god. Volume rocker, play/pause/multifunction button, and a system button. Click feel is tactile and satisfying. No accidental skips when you're adjusting the fit.

Beats Solo 4 vs AirPods Max vs Sony XM5

I own all three, so let me break this down simply.

AirPods Max ($549): Superior sound with a wider soundstage, better midrange, and genuine high-fidelity audio. The ANC is best-in-class. Build quality is aluminum and steel — they feel like a tank. But they weigh 385 grams (nearly double the Solo 4), the mesh headband collects sweat and lint, and the Smart Case is a joke. For studio listening or flights, these win. For everything else, they're overkill and heavy.

Sony WH-1000XM5 ($349): Best ANC in the game. Sound profile is warmer and more neutral than the Beats, with better clarity across the frequency range. The over-ear design is comfortable for all-day wear. But they don't fold, the touch controls are finicky, and they're less gym-friendly — they slide off during bench press and trap heat like a winter hat. For commuters and office workers who need silence, the XM5 is the winner.

Beats Solo 4 ($169 on Amazon): Better battery than both, lighter than both, more gym-friendly than both, cheaper than both. The H1 chip integration is better than Sony's multipoint (but not as good as AirPods Max in the Apple ecosystem). Sound quality is behind both. ANC is nonexistent. For the price, though? The Solo 4 carves out a clear niche: active lifestyle, mostly Apple, mostly hip-hop/electronic/pop listeners who prioritize battery and portability over audiophile audio.

Who Is This For?

Let me be direct about who should buy the Beats Solo 4.

Buy these if: You're an iPhone user who works out, commutes, and values battery life above all else. You listen to hip-hop, electronic, pop, or modern R&B. You want something lighter and more portable than AirPods Max. You don't care about ANC because you want situational awareness on the street or at the gym.

Skip these if: You're an Android user. You want ANC. You listen to classical, jazz, or acoustic music regularly. You wear headphones for 4+ hours straight and need over-ear comfort. You're an audiophile looking for detail retrieval and soundstage.

For the current street price of ~$169 (down from $199), the Solo 4 are a genuinely great value proposition if you fit the profile. They're not the best-sounding headphones, they're not the most comfortable for long sessions, and they lack ANC. But the battery life is generation-defining, the Apple integration is superb, and the gym performance is unmatched by any over-ear competitor.

For me personally? They've become my daily drivers for the gym, the commute, and casual listening around the house. I still reach for the AirPods Max for focused listening sessions, and the XM5 stay on my desk for work calls where I need silence. But for everything else — 80% of my listening — the Solo 4 are the pair I grab first.

And that's probably the highest compliment I can give.
