If you want a rugged, purpose-built hard shell that keeps a pair of Beats Solo on-ear headphones safe on the move, choose ZUJFPL EVA Hard Case; if you need a wearable, wireless on-ear listening band you can actually sleep, run and take calls in, choose Perytong 2-Pack. These are two completely different answers to the same "portable on ear" search — one is armor for your headphones, the other is the headphones. Read the next few minutes before you commit, because picking the wrong one is an easy mistake, and if you mostly care about hands-free calls, the choice gets very clear very fast.
• ZUJFPL EVA Hard Case — biggest strength: a molded EVA shell (6.6 x 5 x 2.7 in) with a dedicated accessory grid, built to take impact, dust and scratches so your Beats Solo 2/3/4 survive a backpack or carry-on.
• ZUJFPL EVA Hard Case — biggest trade-off: it's a case, not headphones. No audio, no Bluetooth, no battery — and the headphones themselves are not included.
• Perytong 2-Pack — biggest strength: a washable spandex headband with ultra-thin on-ear discs, Bluetooth up to 45 ft, a built-in mic and roughly 14 hours of playback per charge.
• Perytong 2-Pack — biggest trade-off: it's a soft, snug sleep-and-sport band, not a hard-shell protector, and it isn't designed to hold or shield a separate pair of headphones.
• Who each is for: ZUJFPL for anyone who already owns Beats Solo on-ear headphones and wants travel-grade protection; Perytong for anyone who wants a wearable, wireless on-ear band for sleep, workouts and calls.
The ZUJFPL case exists for one job: getting a pair of Beats Solo 2, Solo 3 or Solo 4 wireless on-ear headphones from point A to point B without drama. The shell is molded from EVA (ethylene vinyl acetate), which is the same family of semi-rigid foam used in a lot of protective gear, and the spec sheet calls out semi-waterproof, shockproof and dustproof behavior. Translation: a knock against a door frame, a tumble off a seat, a little rain on the walk to the car — none of that should reach the headphones inside. The outside dimensions are 6.6 inches long, 5 inches wide and 2.7 inches high, sized specifically around the Solo line rather than as a generic one-size-fits-all pouch. At 4.5 ounces it adds barely anything to a bag.
Who should buy it: anyone who already owns Beats Solo on-ear headphones and treats them as a daily-carry item — commuters, students, frequent flyers, or somebody who just wants the headphones to still look new in a year. It's also a sensible gift for a Beats owner, and the listing frames it as suitable for family, friends or a partner. Who should skip it: anyone who doesn't own Beats Solo 2, 3 or 4 headphones, and obviously anyone shopping for actual audio gear. To be blunt, if you clicked on "portable on ear headphones" hoping to listen to something, this is the wrong product. It's the box, not the music. One more thing worth repeating because it's easy to miss: the case ships alone — the headphones are not included.
Perytong 2-Pack: Who It's For
The Perytong 2-Pack is the opposite kind of product, and honestly the more interesting one for anyone who wants to wear on-ear audio rather than store it. Instead of a rigid shell, you get a soft spandex headband with extremely thin on-ear discs tucked inside. The ear placement is on-ear, the driver is a dynamic driver covering 20 Hz to 20,000 Hz, and the whole thing is wireless-only — there's no headphone jack at all. Bluetooth range is listed at up to 45 feet, so you can leave your phone on the nightstand or across the gym floor and keep listening.
The comfort story is the point here. The band is made from a breathable, stretchy material that the spec sheet says is fully washable, with the obvious caveat that you remove the speakers first. It stretches to fit most adult head sizes, and the ultra-thin discs are designed so you don't feel a lump when you roll onto your side. That's why the listing pitches it for side sleepers, naps, meditation, ASMR, yoga, running, jogging and travel — plus blocking light, absorbing sweat and keeping ears warm. It's a headband, an eye mask and a pair of headphones in one, which is a genuinely unusual combination.
For calls, the built-in microphone and the on-band volume and control buttons matter. You can answer a hands-free call and skip tracks without pulling out your phone, which is exactly what you want when your hands are full or your eyes are closed. Battery is a USB-rechargeable cell: about 2 to 2.5 hours to charge, more than 14 hours of playback. The brand also lists a 2-year warranty. And because it's a two-pack, you get two headbands — one for home, one for the office or as a gift — plus a USB-C cable and a manual.
Side-by-Side: Which Should You Choose?
• Best for protecting existing Beats Solo headphones → ZUJFPL EVA Hard Case. Molded EVA shell, fitted 6.6 x 5 x 2.7 in interior, accessory grid in the lid.
• Best for actually listening wirelessly → Perytong 2-Pack. Bluetooth up to 45 ft, dynamic drivers, 20 Hz–20,000 Hz.
• Best for calls → Perytong 2-Pack. Built-in microphone plus on-band volume and track controls for hands-free answering. If you're hunting for the best open ear headphones for calls, this hands-free setup is the closer match of the two.
• Best for sleep and side sleeping → Perytong 2-Pack. Ultra-thin on-ear discs and a soft, breathable, washable spandex band.
• Best for travel durability → ZUJFPL EVA Hard Case. Shockproof, dustproof, semi-waterproof, 4.5 ounces, with a carry handle for one-handed hauling.
• Best for battery life → Perytong 2-Pack. Over 14 hours of playback from a roughly 2–2.5 hour charge.
• Best for two people or two locations → Perytong 2-Pack. You get two headbands, one USB-C cable and a manual in the box.
• Best for a gift for a Beats owner → ZUJFPL EVA Hard Case. It's a practical add-on for someone who already has Solo 2, 3 or 4 headphones.
In my opinion, the Perytong 2-Pack is the one I'd buy — with one big condition. If your goal is portable on-ear listening, sleep, workouts and especially calls, it does the actual job: wireless audio, a mic for hands-free answering, over 14 hours per charge, and a washable band you can wear all night. The ZUJFPL case is excellent at what it does, but it does not play a single note. The condition is simple: if you already own Beats Solo 2, 3 or 4 headphones and your real problem is keeping them intact in a bag, buy the ZUJFPL case instead and check the current price on Amazon before you decide.
what are the best open ear headphones
"Best" depends on what you need them for. In this comparison, the Perytong 2-Pack is the on-ear wireless option — thin on-ear discs, Bluetooth up to 45 ft, a built-in mic and 14+ hours of playback. The ZUJFPL EVA Hard Case isn't a headphone at all; it's a protective case for Beats Solo 2/3/4.
are on ear headphones good
They can be. On-ear designs like the Perytong band sit against the ear rather than inside it, which many people find more comfortable for long sessions, sleep and workouts. The trade-off is less isolation than an in-ear or over-ear design, so they're better for quiet rooms, side sleeping and light activity than for loud commutes.
are open ear headphones good
They're good when you want to stay aware of your surroundings and avoid stuffing anything into your ear canal. The Perytong band's ultra-thin on-ear discs and breathable spandex fit that idea well for sleep, yoga, running and meditation. Just don't expect heavy noise blocking — that's not what this style is for.
what are the best in-ear headphones
That's a different category from either product here. Neither the ZUJFPL case nor the Perytong 2-Pack is an in-ear model — the Perytong is on-ear, and the ZUJFPL is a storage case. If in-ear fit is what you want, you'd be shopping outside this comparison entirely.
