You’ve seen them everywhere. On the subway, at the gym, or hanging around the neck of every third college student on campus. The JBL Tune 510BT is basically the "white t-shirt" of the audio world—simple, reliable, and cheap enough that you don't have a heart attack if you accidentally leave them in a Starbucks booth.
But honestly? Most "audiophiles" hate them. They’ll tell you the soundstage is narrow or the plastic feels like it came out of a 3D printer from 2012. Yet, despite being out for years, these headphones still outsell brand-new, high-tech releases. Why? Because JBL stumbled onto a formula that most tech companies overthink. People just want stuff that works without needing a firmware update every Tuesday.
The Battery Life That Actually Changed Things
Back when the JBL Tune 510BT launched, the big selling point was the 40-hour battery life. Today, 40 hours is standard, maybe even a little low compared to some of the marathon-runners from Sony or Sennheiser. But in the real world, 40 hours is "I forgot to charge these for a week and they still turned on" territory.
The hero here isn't just the capacity; it’s the USB-C speed. You’ve probably been there—running late, realizing your gear is dead, and panicking. JBL’s quick charge gives you about two hours of playback from a five-minute plug-in. It’s a lifesaver. No, really.
I remember talking to a commuter in New York who swore by these because they survived a literal winter of being tossed into a backpack without a case. That’s the thing about the 510BT. They are rugged precisely because they aren't precious. There’s no delicate leather to scuff or glass touchpads to crack. It’s just reinforced polycarbonate and some decent hinges.
What Most People Get Wrong About "Pure Bass"
JBL markets these with the "Pure Bass" branding. If you look at frequency response graphs from sites like RTINGS or SoundGuys, you’ll see exactly what that means. There is a massive hump in the low end.
Is the sound "accurate"?
Not even close.

If you’re trying to hear the subtle breath of a flutist in a classical recording, you’re looking at the wrong product. But if you’re listening to 21 Savage or a heavy techno set while hitting a personal best on the bench press, that bass boost is exactly what you need. It’s punchy. It’s aggressive. It masks the sound of the gym's terrible overhead speakers.
One thing that gets overlooked is the lack of a 3.5mm jack. This is a purely wireless experience. For some, that’s a dealbreaker. But let’s be real: when was the last time you actually used a dongle for your phone? JBL bet on the wireless future early with this model, and for the price point, they chose to spend the budget on the Bluetooth 5.0 stability rather than adding an analog port nobody would use.
The Multi-Point Connection Magic
Multi-point connection used to be a premium feature. You’d pay $300 for Bose QuietComforts just to have the headphones stay connected to your laptop and phone simultaneously. The JBL Tune 510BT brought that to the "under $50" crowd.
It’s finicky sometimes. I’ve heard users complain that if a notification pings on their phone while they’re watching a movie on their iPad, the audio takes a second to switch back. It’s not perfect. But having it at all in this price bracket is wild. It makes these a legitimate tool for students who need to flip between a Zoom lecture and a phone call without fumbling through Bluetooth settings.
Comfort, or Lack Thereof?
Here is the honest truth: these are on-ear headphones.
On-ear (supra-aural) designs are a polarizing choice. Because the pads sit directly on your cartilage rather than around it, they can get "clampy" after about two hours. If you wear glasses, the struggle is real. The pressure presses the stems of your frames against your temples.

However, the trade-off is portability. These things fold up into a ball. They fit in a jacket pocket. You can’t do that with a pair of massive over-ear cans. The ear cushions are made of a synthetic protein leather that, quite frankly, will start to flake after 18 months of heavy use. But since replacements are about $8 on Amazon, most people don't care.
Why They Still Outperform Newer Models
Tech companies love to add "features." They add gesture controls that don't work when it's raining. They add "find my headphones" apps that drain your phone battery. They add AI-upscaling that makes your music sound like it’s underwater.
The JBL Tune 510BT has physical buttons. Real, tactile, "clicky" buttons.
- You press the button, the volume goes up.
- You hold the button, the track skips.
- You double-tap, and Siri or Google Assistant wakes up.
There is a reliability in physical controls that touch sensors just can't match, especially if you're wearing gloves or have sweaty hands. In an era where everything is becoming a "smart" device, the 510BT is refreshingly "dumb" in the best way possible. It doesn't need an app. You don't need to create an account to use them. You pair them, and you play music.
The Sustainability Paradox
We have to talk about the "disposable" nature of budget tech. Because these are so affordable, many people treat them as replaceable. That’s a problem for the environment. However, because they are so mechanically simple, they actually tend to last longer than more complex electronics. There are fewer points of failure. No active noise canceling (ANC) microphones to glitch out. No complex software to get "bricked" by an update.
I’ve seen 510BTs that look like they’ve been through a war zone—scratched, faded, and dented—yet they still sync instantly. That durability is a form of sustainability in itself.

Actionable Advice for Potential Buyers
If you’re looking at these right now, don't pay the full MSRP. These are almost always on sale. Check retailers like Target, Best Buy, or Amazon during any holiday window. If you're paying more than $40, you're doing it wrong.
For those who already own them and find them too tight, try stretching them over a stack of books overnight. It loosens the plastic headband tension just enough to make long study sessions bearable. And if you’re a heavy sweater, wipe down the pads after your workout. Salt from sweat is the primary reason the ear cushions start to peel.
If you need silence for a long flight, these won't help you. They have zero active noise cancellation. They rely entirely on the physical seal of the pad against your ear. For a loud airplane engine, you'll still be cranking the volume to dangerous levels just to hear your podcast. In that specific case, save up for the JBL Tune 710BT or a pair of Sony CH-720Ns.
But for everything else? For the dog walks, the gym sessions, the "I just need to hear this YouTube video while my roommate is sleeping" moments? The 510BT is the gold standard of "good enough." It’s proof that sometimes, the best technology isn't the most advanced—it's the most practical.
Next Steps for 510BT Owners:
- Check your firmware: Even though they don't need an app, checking the JBL Headphones app once can sometimes improve multi-point stability.
- Buy backup pads: If you plan on keeping these for years, grab a pair of replacement cushions now while they are still widely available.
- Optimize your EQ: If the bass is too much, use your phone's built-in EQ settings (like "Small Speakers" or "Treble Boost") to balance out the sound for acoustic tracks.
