• Sony MDR-XB600 — biggest strength: a large 40mm dynamic driver paired with Sony's direct vibe structure, which the spec sheet ties directly to a tight acoustic seal and powerful bass response.
• Sony MDR-XB600 — biggest trade-off: it's a wired on-ear model with a 1.2m cord and no carrying case — just the cable and ear cushions in the box.
• ソニー(SONY) MDR — biggest strength: a compact, highly sensitive 12mm driver with a dedicated "Base Booster," hybrid earpieces in four sizes, a clip and a carrying pouch.
• ソニー(SONY) MDR — biggest trade-off: it's a small in-ear design with no noise control at all, so it does nothing to block the world out.
• Buy the Sony MDR-XB600 if you want a larger driver, pressure-relieving foam pads and a folding frame you can toss in a bag.
• Buy the ソニー(SONY) MDR if you want something that disappears in your pocket, stays put in your ears and comes with everything you need out of the box.
The MDR-XB600 is the bigger, more deliberate piece of hardware here. Its headline spec is a 40mm dynamic diaphragm, and Sony pairs that with what it calls a direct vibe structure — the idea being that a tight acoustic seal lets the driver's energy go into your ear instead of leaking away. That's the whole reason a 40mm driver exists in a portable headphone: more surface area moving air, which is how you get the low-end weight this XB series is built around.
Two details matter for daily use. First, the pressure-relieving foam ear pads. On-ear designs clamp against the ear, and foam that spreads that pressure is the difference between a two-hour session and a twenty-minute one. Second, the dual folding design. It collapses down for storage, which is the practical answer to "where do I put these when I'm not wearing them." The cord is a Y-type flat serrated cable at 1.2m — flat cables resist tangling, and a serrated edge is Sony's extra measure against knots.
ソニー(SONY) MDR: Who It's For
The ソニー(SONY) MDR goes the other direction entirely. It's an in-ear model built around a small, highly sensitive 12mm driver, and the feature Sony leads with is the "Base Booster," which it describes as conveying the groove feeling of deep bass straight to your ear. A small driver that's highly sensitive is easy to drive — that's the engineering logic behind a bud like this, and it's why in-ears can punch above their size on low end when the seal is right.
The kit is where this one earns its place. You get hybrid earpieces in SS, S, M and L, two of each, plus a clip and a carrying pouch. Four sizes of hybrid tips isn't padding — it's the difference between a seal that gives you bass and a seal that gives you nothing. Sony also lists high magnetic neodymium magnets in the driver, which is the standard way to get more control and output from a small motor. The cable is a tangle-free serrated design, same anti-knot thinking as the bigger model.
Who should buy it? Commuters, gym-goers, anyone who wants headphones that vanish into a pocket. The item weight is listed at 8g, and the design notes say "comfortable and not easy to fall off" — that's the whole pitch for an in-ear with a clip. The color is red and the enclosure is plastic. Skip it if noise is your problem: noise control is listed as none, and there's no remote on the cable. It's a music-only, wired, 3.5mm bud. Nothing more, and it doesn't pretend to be.
Side-by-Side: Which Should You Choose?
• Best for low-end weight → Sony MDR-XB600. A 40mm dynamic driver simply moves more air than a 12mm one.
• Best for long listening sessions → Sony MDR-XB600. Pressure-relieving foam pads are built for exactly that; small buds can start to irritate over hours.
• Best for fit options → ソニー(SONY) MDR. Four hybrid eartip sizes (SS, S, M, L, two of each) versus one fixed on-ear pad.
• Best for storage → ソニー(SONY) MDR. It ships with a carrying pouch; the XB600 relies on its dual-folding frame and nothing else.
• Best for isolation → Sony MDR-XB600. Its specs list sound isolation; the ソニー(SONY) MDR lists noise control as none.
• Best for easy packing → Sony MDR-XB600. The dual folding design collapses compact, which a fixed on-ear otherwise can't do.
• Best for out-of-the-box completeness → ソニー(SONY) MDR. Clip, pouch, four tip sizes and a warranty card versus a cable and ear cushions.
In my opinion, the Sony MDR-XB600 is the one I'd buy if bass is genuinely the point of the purchase. A 40mm dynamic driver, a direct vibe structure for a tight seal, foam pads built for long sessions and a frame that folds flat — that's a coherent set of choices all aimed at one goal. The ソニー(SONY) MDR is the smarter pick if your listening happens on the move, and its eartip selection and included pouch are genuinely thoughtful. But for a deep-bass-first listener who mostly sits down to listen, I'd take the XB600.
how to pair sony extra bass headphones
Pairing only applies to wireless models. Both headphones on this page are wired, connecting through a 3.5mm jack, so there's no Bluetooth pairing step — you plug them in and they play. If you own a wireless Sony Extra Bass model, pairing is done through your phone's Bluetooth menu.
how to connect sony extra bass headphones
Connect either of these by plugging the 3.5mm jack into your phone, laptop or player. The Sony MDR-XB600 uses a 1.2m Y-type flat serrated cord, and the ソニー(SONY) MDR uses a tangle-free serrated cable. No adapter, app or setup is required for either.
how to connect jvc deep bass wireless headphones
That's a different brand and not covered by either data sheet here. For any wireless deep-bass headphone, the general method is to put the headphones into pairing mode and select them from your device's Bluetooth settings. Check that model's own manual for the exact button sequence.
what is deep bass in headphones
Deep bass refers to the lowest audible frequencies — the rumble and thump below the vocal range. The Sony MDR-XB600 lists a 4–24Hz frequency range with a 40mm dynamic driver, while the ソニー(SONY) MDR uses a 12mm driver, a Bass Booster and neodymium magnets to emphasize that low end. In both cases, a proper seal is what actually lets you hear it.
