How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a wired in-ear headphone built around air tube technology and a real wood housing, choose Symphonized Wooden Airtube Headphones; if you need a foldable over-ear headset with soft cushions, an inline mic and a USB-C adapter in the box, choose Zollexa Over-Ear Headphones. These two barely compete for the same buyer. One sits inside your ear and leans on materials and signal-reduction design. The other sits around your ears and leans on comfort, storage and call-friendly controls.
• Symphonized — biggest strength: Air tube technology plus a genuine wood housing, with foam and silicone ear tips in multiple sizes and a 1-year warranty.
• Symphonized — biggest trade-off: It's an in-ear design with no USB-C adapter and no dedicated over-ear cushioning, so it won't suit anyone who dislikes things sitting in the ear canal.
• Zollexa — biggest strength: A foldable, adjustable over-ear build with soft protein leather cushions, an inline mic, and both a 3.5mm plug and a USB-C adapter for laptops and phones.
• Zollexa — biggest trade-off: There is no noise control of any kind on the spec sheet, and it's bulkier than any in-ear option even when folded.
• Who Symphonized is for: Listeners who want an in-ear fit, wood-bodied sound and air tube design, and who mostly plug into a 3.5mm jack.
• Who Zollexa is for: Adults who want an over-ear headset for calls, meetings and travel, and who need it to work with both a 3.5mm jack and USB-C.
Symphonized's pitch here is unusual, and that's the whole point. These are in-ear headphones built around air tube technology, which the brand describes as a way to reduce EMF exposure while still delivering clear audio. Whether or not that's the reason you're shopping, it's the defining feature: this is a headphone designed for someone who is actively thinking about signal exposure during long listening sessions, not just about bass response.
The second pillar is the housing. Real wood, not plastic. Symphonized says the wood construction produces a 3D audio character with deep bass and crisp highs, and the driver is rated across a 20 Hz to 20,000 Hz frequency range — the standard full-range span, so nothing is being artificially narrowed. The fit is handled with foam and silicone ear tips in multiple sizes, and the brand's own framing is useful: foam tips block outside noise for focused listening, while silicone tips give a softer, more flexible seal. That's effectively two different listening experiences from one pair.
Practical stuff: a universal 3.5mm jack, a built-in microphone, and volume control on the cable. Control method is listed as touch, noise control is listed as sound isolation, and it ships with a 1-year warranty.
Who should skip it? Anyone who finds in-ear tips uncomfortable over long stretches. Anyone who needs a USB-C connection without an adapter. And anyone who wants the pressure-relieving feel of cushions around their ears rather than inside them.
Zollexa Over-Ear Headphones: Who It's For
Zollexa goes the other direction entirely — this is a conventional wired over-ear headset, and it's honest about it. The model is MA569, finished in dark blue with faux leather, and the design is over-ear with round earpieces. The cushions are soft protein leather, and Zollexa's stated goal is reducing pressure during longer listening sessions. There's an adjustable headband so you can actually dial in the fit rather than hoping one size works.
The connectivity is where it gets genuinely useful for a lot of people. You get a 3.5mm plug, but you also get a USB-C adapter in the box. That single inclusion is why I'd point a laptop user here over almost anything else in this category — plenty of modern laptops and phones have dropped the headphone jack, and an adapter in the box means one less thing to buy and one less thing to lose.
The inline mic and in-cable controls cover volume and audio management, and Zollexa specifically frames the mic around everyday voice pickup for office calls, video chats and casual gaming. It's not marketed as a studio microphone; it's marketed as something that works when you're on a call.
The foldable, lightweight build is the third leg. It stores in a backpack, drawer or carry-on, which matters if this headset lives in a bag. And the warranty is 2 years from the manufacturer — longer coverage than the Symphonized pair offers.
Who should buy it? Adults who want dependable wired sound for meetings, calls and travel, who prefer over-ear comfort, and who need it to work with both older 3.5mm gear and newer USB-C devices. Zollexa's own framing says it plainly: for people who want dependable sound without paying for wireless features they don't need.
Who should skip it? Anyone who needs active noise cancellation — there is no noise control listed here at all, which is a real difference from the Symphonized pair's sound isolation. And anyone who wants maximum portability, because even a foldable over-ear takes up more room than a pair of in-ears.
• Best for in-ear fit and portability → Symphonized Wooden Airtube Headphones. In-ear, small, and easy to pocket.
• Best for long listening sessions without ear-canal pressure → Zollexa Over-Ear Headphones. Protein leather cushions and an adjustable headband are built for exactly that.
• Best for reducing outside noise → Symphonized Wooden Airtube Headphones. Sound isolation is listed, and the foam tips are specifically described as blocking outside noise. Zollexa lists no noise control.
• Best for laptop and modern phone compatibility → Zollexa Over-Ear Headphones. The included USB-C adapter is the difference-maker if your device has no headphone jack.
• Best for calls and online meetings → Zollexa Over-Ear Headphones. The inline mic is explicitly designed for voice pickup on calls and video chats, and controls sit on the cable.
• Best for material and design character → Symphonized Wooden Airtube Headphones. Genuine wood housing and air tube technology are the entire identity of this pair.
• Best for storage and travel packing → Zollexa Over-Ear Headphones. It folds, which an in-ear obviously doesn't need to.
• Best warranty coverage → Zollexa Over-Ear Headphones. Two years from the manufacturer versus one year on the Symphonized pair.
• Best for fit customization → Symphonized Wooden Airtube Headphones. Two tip materials in multiple sizes lets you tune both comfort and isolation.
If I'm buying for myself and I mostly plug into a laptop, join calls, and want one headset that survives a backpack, I'd buy the Zollexa Over-Ear Headphones. The USB-C adapter, the inline mic, the foldable frame and the 2-year warranty cover the widest range of everyday wired use, and over-ear cushions are simply more comfortable for long sessions in my opinion. I'd only switch to the Symphonized Wooden Airtube Headphones if the air tube design and wood housing are what drew me in, or if I specifically wanted an in-ear pair with foam tips for blocking out a commute. Two different jobs, two different answers.
FAQ
No. The spec sheet lists sound isolation rather than active noise cancellation. In practice, the foam ear tips are described as blocking outside noise for focused listening, which is passive isolation from the seal, not electronic cancellation.
Yes — that's the point of the included USB-C adapter. You get a standard 3.5mm plug plus the adapter, so the headset covers both older 3.5mm devices and newer USB-C laptops and phones.
They solve comfort differently. Zollexa uses soft protein leather over-ear cushions and an adjustable headband to reduce pressure, which suits people who dislike in-ear tips. Symphonized gives you foam and silicone tips in multiple sizes so you can tune the fit inside your ear. If in-ears bother you, go Zollexa.
Zollexa carries a 2-year manufacturer warranty and includes a USB-C adapter alongside its 3.5mm plug. Symphonized carries a 1-year warranty and connects via a 3.5mm jack only. For the current price on either, check the Amazon listing — I don't quote prices here because they change.
