If you want the extra-bass headphone that doubles as a phone headset with app-based control, choose Sony MDRXB950AP/H; if you need a studio/DJ-style over-ear with bigger drivers and a retractable cable, choose Souz Collection Pure BEATZ Professional. Both chase deep bass, but they chase it from different directions — one is a smartphone-first daily driver, the other is a budget studio/DJ tool. Here's how I'd split them.
• Sony MDRXB950AP/H — biggest strength: Acoustic Bass Booster plus 40mm dynamic drivers tuned for unmistakable low-end, backed by an in-line mic, a SmartKey app for customizable remote functions, and a tangle-free Y-type cord.
• Sony MDRXB950AP/H — biggest trade-off: It's built around phone use, so its 3–28 kHz range and 40mm drivers won't reach as deep or as loud as a dedicated studio can.
• Souz Collection Pure BEATZ Professional — biggest strength: 50mm drivers, neodymium magnets, an Acoustic Bass Booster and a gold-plated 3.5mm plug — a spec sheet aimed squarely at DJ, live and studio work.
• Souz Collection Pure BEATZ Professional — biggest trade-off: It's wired-only with no microphone or app features listed, so it's less convenient as an everyday phone headset.
• Buy the Sony if you want one pair for calls, streaming and commuting with app-tunable controls.
• Buy the Souz if you want maximum bass driver size and a studio/DJ look for critical listening at home.
The Sony MDRXB950AP/H is a wired over-ear headphone with a clear dual identity: it's a bass headphone and a phone headset at the same time. The Acoustic Bass Booster and 40mm dynamic drivers are the engine behind that deep, punchy low end, and the 3–28 kHz frequency range tells you Sony tuned this for a lively, bass-forward response rather than flat reference monitoring. Around-the-ear cushions, an aluminum build and a swivel design for portability round out the design — this is a headphone meant to leave the house.
What makes it stand out for a specific buyer is the smartphone layer. There's an in-line microphone for hands-free calling, compatibility with both Apple and Android phones, and the free SmartKey app that lets you customize what the in-line remote does. In my opinion, that combination is the real reason to pick this one. The 1.2m tangle-free Y-type cord is short enough to be pocket-friendly and long enough for a phone in your jacket.
Who should buy it: anyone who wants one wired headphone for music, calls and podcasts on a phone, and who likes the idea of remapping the remote to their own habits. Who should skip it: if you want a headphone built for studio monitoring or DJ cueing, or if you specifically need the larger driver and studio-first feature set of a DJ-style can, the Sony's phone-centric design is the wrong tool — even though it lists Active Noise Cancellation among its controls, that doesn't change what the rest of the design is for.
The Souz Collection Pure BEATZ Professional (SPB 018) reads like a DJ/studio headphone first and everything else second. The headline number is the 50mm speaker — noticeably larger than the Sony's 40mm — paired with neodymium magnets, which the brand frames around higher magnetic density and efficiency. Add the Acoustic Bass Booster and the gold-plated 3.5mm plug, and you get a package aimed at "excellent subwoofer effect," meaning it leans hard into sub-bass rather than just mid-bass thump.
The design language backs that up: aluminum enclosure material, a black finish, soft leather cushions to reduce fatigue over long sessions, and a folding over-ear shape with a retractable cable — genuinely useful if you're packing it between gigs or a desk setup. The 32-ohm impedance is a friendly figure for phones, laptops and portable players, so you don't strictly need a headphone amp to drive it.
Who should buy it: DJs, home-studio users, and anyone who wants a bass-heavy over-ear with a bigger driver and a cable that hides away when not in use. Who should skip it: if you need a built-in microphone, app-customizable controls or a tangle-free fixed cord designed for phone calls, the Souz doesn't list those. It's also a wired-only headphone, so there's no wireless freedom here either.
Side-by-Side: Which Should You Choose?
• Best for app-tunable controls → Sony MDRXB950AP/H. The free SmartKey app customizes the in-line remote.
• Best for the largest bass driver → Souz Collection Pure BEATZ Professional. 50mm vs. the Sony's 40mm.
• Best for DJ, live and studio use → Souz Collection Pure BEATZ Professional. That's the stated intent of its design.
• Best for cable management → Souz Collection Pure BEATZ Professional. Retractable cable beats a fixed cord for packing.
• Best for tangle-free everyday portability → Sony MDRXB950AP/H. The 1.2m Y-type cord and swivel design are built for commuting.
• Best for cross-platform phone compatibility → Sony MDRXB950AP/H. It's explicitly compatible with Apple and Android.
• Best for long listening sessions → Souz Collection Pure BEATZ Professional. Leather cushions are described as reducing fatigue over long use.
If I were buying for myself and my listening mostly happens on a phone — music, calls, podcasts, the walk to work — I'd take the Sony MDRXB950AP/H. The in-line mic, the SmartKey app and the tangle-free cord make it the more useful object day to day, and the Acoustic Bass Booster still gives you the deep-bass character you came for. I'd only switch to the Souz Collection Pure BEATZ Professional if my priority were the bigger 50mm driver, a studio/DJ build and a retractable cable, and I didn't care about phone-call features. In my opinion, the Sony is the safer everyday pick and the Souz is the specialist.
FAQ
how to pair sony extra bass headphones
how to connect sony extra bass headphones
Connect the 1.2m Y-type cord's 3.5mm plug to your device, then use the in-line remote for playback and calls. The SmartKey app lets you customize what the in-line remote buttons do, so install it first if you want custom control. It's compatible with both Apple and Android smartphones.
how to connect jvc deep bass wireless headphones
I can't cover JVC here — this comparison is between the Sony MDRXB950AP/H and the Souz Collection Pure BEATZ Professional, and neither is a JVC model. For the Souz, connection is simple: plug the gold-plated 3.5mm stereo mini plug into your device. It's a wired headphone, so there's no Bluetooth pairing step.
what is deep bass in headphones
Deep bass is the low-frequency end of the range — the sub-bass and bass you feel as much as hear. Both headphones here target it with Acoustic Bass Booster technology: the Sony via 40mm dynamic drivers across a 3–28 kHz range, and the Souz via 50mm drivers with neodymium magnets and a 32-ohm impedance. Bigger drivers and stronger magnets generally push more low-end energy.
