How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want week-long wireless playback from a plush over-ear pair with a 3.5 mm jack as a backup, choose Cleer Audio Enduro 100; if you need a pocketable USB-C corded set with a wooden housing and an inline remote, choose Symphonized Wooden USB-C.
• Cleer Audio Enduro 100 — biggest strength: up to 100 hours of playback, a 10-minute quick charge that yields 12 hours, and 40 mm Ironless drivers in a 280 g over-ear frame that also accepts a 3.5 mm cable.
• Cleer Audio Enduro 100 — biggest trade-off: it's a full-size over-ear headphone, so it's bulkier and heavier than a pocket set, and the wireless side leaves you managing a charge every few days.
• Symphonized Wooden USB-C — biggest strength: a true corded design with a USB-C plug, an in-line remote for calls and volume, and a Bubinga wood housing in an 8 mm dynamic driver that weighs just 0.12 kg.
• Symphonized Wooden USB-C — biggest trade-off: it's wired only, so the cord ties you to the device, and passive noise cancellation means it relies on your ear-tip seal rather than electronics.
• Pick Cleer Audio Enduro 100 if you want one pair for travel, work and long listening sessions without thinking about a charger.
• Pick Symphonized Wooden USB-C if you want a lightweight corded set that lives in a pocket or bag and plugs straight into a USB-C phone or laptop.
The Enduro 100 is built around one idea: never make the listener think about power. Cleer rates it at up to 100 hours of playback, with three hours to a full charge and a 10-minute quick charge worth 12 hours. That math matters in real life. A daily commuter who listens two hours a day is looking at roughly seven weeks between charges. A long-haul flight, a week of hotel rooms, a festival weekend — none of those require a charger in the bag.
The sound side is a 40 mm Ironless dynamic driver with a 20 Hz to 20,000 Hz range and Hi-Res capability, tuned for bold, articulate output with low distortion and deep bass. Volume, playback, calls and voice-assistant control sit on tactile buttons on the left earcup, which I prefer to touch surfaces when I'm wearing gloves or walking. Bluetooth 5.0 handles the wireless link, and a 3.5 mm jack is there when you want a cord.
Who should buy it: people who want one headphone for everything — work calls, podcasts, music, travel — and who value comfort over hours. At 280 g with plush earpads and a flexible headband, plus a foldable design and a small 1.6-ounce carrying case, it packs down better than its size suggests.
Who should skip it: anyone who wants something that disappears into a jeans pocket, and anyone who specifically needs a USB-C plug. The Enduro 100's wired option is 3.5 mm, not USB-C, so a modern phone without a headphone jack needs an adapter. It's also an over-ear, so it makes a visual statement whether you want one or not.
The Symphonized NRG C takes the opposite approach. It's an in-ear, corded headphone with a USB-C connector, an 8 mm dynamic driver, 32 ohm impedance and a frequency range of 18 Hz to 22 kHz. The 18 Hz low end is worth noting: on paper it reaches slightly deeper than the Cleer's 20 Hz figure, which is the kind of detail that matters if you listen to bass-heavy material and get a good seal.
That seal is the whole game here. The kit includes foam and silicone ear tips in three sizes, and the Bubinga wood housing sits at the ear canal entrance — visible when worn, by design, not by accident. Passive noise cancellation on this model isn't electronic; it's the physical blocking you get from a properly fitted tip. Choose the wrong size and you lose both bass and isolation, so the fit guide matters more than it would on an over-ear.
The inline remote handles calls, playback and volume, and there's a built-in HD mic for hands-free talking while commuting or working. Total weight is 0.12 kg, so it's genuinely pocketable and it ships with a carrying case in black to match the wood housing.
Who should buy it: USB-C phone and laptop owners who want a corded set with zero charging, zero pairing and no battery to degrade. Students, commuters and anyone who takes a lot of calls will get the most out of the remote. The age range listed covers adults, teens and kids, so it works as a family spare too.
Who should skip it: iPhone owners on Lightning, anyone who wants wireless freedom, and listeners who dislike in-ear pressure. If you've never gotten along with ear-tip fit, this design will fight you.
Side-by-Side: Which Should You Choose?
• Best for corded, plug-and-play listening → Symphonized Wooden USB-C. A USB-C plug with an inline remote and no battery, pairing or charging involved.
• Best for long-session comfort → Cleer Audio Enduro 100. Over-ear fit, plush pads, flexible headband, 280 g.
• Best for portability → Symphonized Wooden USB-C. 0.12 kg, in-ear, with a carrying case.
• Best for calls on the move → Symphonized Wooden USB-C. Built-in HD mic plus in-line call and volume control.
• Best for travel and flights → Cleer Audio Enduro 100. Foldable, Bluetooth 5.0, and a 3.5 mm jack for in-seat entertainment systems.
• Best for bass depth on paper → Symphonized Wooden USB-C. An 18 Hz low-end rating versus 20 Hz on the Cleer, assuming a good tip seal.
• Best for iPhone 15 through 17 and modern Android → Symphonized Wooden USB-C. Native USB-C, no adapter needed.
I'd buy the Cleer Audio Enduro 100. In my opinion, the 100-hour battery, the quick-charge math, the 40 mm Ironless driver and the 3.5 mm jack make it the more versatile single purchase — it covers wireless listening, wired listening and travel without a charger in your bag. The Symphonized Wooden USB-C is the better second pair: cheap to keep around, USB-C native, and immune to battery aging. If corded is non-negotiable for you, flip the decision and take the Symphonized. Either way, check the current price on Amazon before you commit.
how to wired headphones work
A wired headphone carries the audio signal as an analog or digital electrical signal from your device down the cable to the drivers, which convert it into sound. The Symphonized Wooden USB-C uses a USB-C connection, so the signal is digital up to the point it's converted inside the headphone. The Cleer Enduro 100 can run the same way over its 3.5 mm jack, or bypass the cable entirely over Bluetooth 5.0.
how to use wired headphones with iphone
It depends on the port. The Symphonized Wooden USB-C is specified for iPhone 15 through 17, which use USB-C, so it plugs straight in. Older iPhones with a Lightning port need an adapter, since this model is USB-C only. The Cleer Enduro 100's wired input is 3.5 mm, so it needs a 3.5 mm-to-Lightning or 3.5 mm-to-USB-C adapter on any phone without a headphone jack.
how to fix wired headphones no sound
Work through it in order: reseat the plug, try a different device, and check that the inline remote's volume isn't turned down. On the Symphonized, swap ear tips and confirm the USB-C port is free of lint, since a poor connection is a common cause of one-channel dropouts. If the Cleer is silent on Bluetooth, confirm it's charged and paired, then test the 3.5 mm cable to isolate whether the issue is wireless or the driver itself.
how to wired headphones
Plug the connector into your device, set your volume, and use the inline remote on the Symphonized Wooden USB-C for playback and calls, or the left-earcup buttons on the Cleer Enduro 100 when running wired. Corded listening needs no pairing and no charging, which is the main reason to keep a set like the Symphonized around. Keep the cable slack rather than tight against your body to avoid strain at the plug.
