How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want headphones that stay put through any workout and let you hear traffic while you run, choose RunPhones Classic Exercise Headphones; if you need compact, foldable on-ear headphones with a built-in mic for commuting and calls, choose JVC Flats.
• RunPhones Classic Exercise Headphones — biggest strength: flat speakers sit inside a moisture-wicking, washable headband that stays put and lets ambient sound through for safety during outdoor training.
• RunPhones Classic Exercise Headphones — biggest trade-off: no noise isolation by design, no inline mic or remote, and a bulkier headband format that isn't meant for folding and tossing in a pocket.
• JVC Flats — biggest strength: a foldable stainless steel frame with 30mm dynamic drivers, soft earpads that isolate ambient noise, and an inline remote and microphone.
• JVC Flats — biggest trade-off: the on-ear pads block outside sound, which is great for focus but not ideal when you need to hear your surroundings, and the pads won't wick sweat the way a fabric band does.
• Who each pick is for: choose RunPhones if your priority is secure, sweat-friendly, awareness-first listening for running, yoga, boxing or sleeping; choose JVC Flats if your priority is portable, isolating everyday listening with calls on the go.
The RunPhones Classic is a headband first and a headphone second. The flat speakers live inside a soft, elastic fabric band that sits over your ears rather than inside them. Because nothing enters the ear canal, there's no earbud to wiggle loose mid-stride, and the band doubles as a sweat absorber and a way to keep hair out of your face. It's wired, running on a standard 3.5mm jack, and the speakers are adjustable inside the band so you can line them up over your ears. The fabric enclosure is designed to be washed — pull the electronics out first, then toss the band in with your laundry.
Who should skip it? Anyone who wants to disappear into their music. There's no noise control here at all — the design intentionally lets outside sound in. If you're on a loud train or in a busy office and want to block the world out, this isn't the tool. It also has no inline microphone or remote, so taking calls isn't part of the package. And if you want something that folds flat into a jacket pocket, the headband format is a different animal.
JVC Flats: Who It's For
The JVC Flats is a conventional on-ear headphone built around portability and isolation. The frame folds flat, which makes it easy to slip into a bag, and the adjustable stainless steel headband is made to fit a range of head sizes while holding up to daily use. Inside are 30mm Neodymium dynamic drivers, which is the spec behind the bass and treble response JVC describes. The soft earpads do double duty: they cushion extended listening sessions and they block ambient noise, which is the opposite philosophy from the RunPhones approach.
The wired connection uses a 3.5mm jack with a gold-plated slim plug, and there's an inline remote and microphone for media control and calls. At 5.12 ounces it's heavier than the RunPhones headband, but that weight comes with a rigid steel structure rather than fabric. JVC backs it with a one-year parts and labor warranty.
This is the headphone for the commute, the noisy open-plan office, or a long study session where you want the room to fade out. The mic and remote make it a practical choice for phone calls and skipping tracks without pulling out your device. If you want one pair that lives in your bag and handles both music and calls, the Flats fits that role well.
Where it falls short for a fitness buyer: the isolating pads work against you outdoors, since you won't hear approaching traffic the way you would with the RunPhones. The earpads and steel frame also aren't built around sweat management the way a washable fabric band is, so for heavy training sessions they're the less natural fit.

• Best for commuting, offices and noisy environments → JVC Flats. The soft earpads isolate ambient sound to help you focus.
• Best for calls and track control → JVC Flats. It has an inline remote and microphone; RunPhones has neither.
• Best for sweat and hair management → RunPhones Classic Exercise Headphones. The moisture-wicking band absorbs sweat and keeps hair out of your face, and the fabric section is washable.
• Best for portability → JVC Flats. The flat foldable design slips into a bag; the RunPhones headband doesn't fold.
• Best for sleeping or lying on your side → RunPhones Classic Exercise Headphones. Nothing goes inside the ear, so there's nothing to press against your head.
• Best for durability structure → JVC Flats. The adjustable stainless steel headband is built for everyday wear, backed by a one-year parts and labor warranty.
• Best for audio drivers → JVC Flats. 30mm Neodymium dynamic drivers versus the RunPhones' flat-speaker design.
If I had to pick one, it would come down to what I'm buying it for. For fitness and anything where I need to stay aware of my surroundings, I'd buy the RunPhones Classic Exercise Headphones — the washable headband, the adjustable flat speakers and the no-earbud design solve the exact problem that ruins workouts for a lot of people. For everyday listening, commuting and calls, I'd buy the JVC Flats for its foldable frame, 30mm drivers, isolation and inline mic. Two different jobs, two different tools.

FAQ
are on ear headphones good
what are the best open ear headphones
"Open" in the sense of letting outside sound in describes the RunPhones Classic, since ambient noise filters through the band while your audio plays. That design keeps you aware of traffic and surroundings during outdoor training. If you specifically want isolation instead, the JVC Flats blocks ambient sound with its earpads.
are on ear headphones comfortable
The JVC Flats uses soft earpads and an adjustable stainless steel headband designed to fit different head sizes, which supports comfortable extended listening. Comfort is personal, but the adjustable frame and padded earcups are built for longer sessions. The RunPhones takes a different route: nothing enters the ear, so there's no bud pressing inside.
are headphones less harmful than earphones
Both the RunPhones and the JVC Flats are over- or on-ear designs that sit outside the ear canal rather than inside it, which is the main structural difference from in-ear models. The RunPhones is also not noise-canceling, so ambient sound reaches you while you listen. Volume and listening duration matter more than the category alone.
