• Sony Mdrxb450Ap — biggest strength: An Acoustic Bass Booster paired with 30mm dynamic drivers tuned for a wide 5 Hz–22 kHz range, in a lightweight wired design that never needs a charge.
• Sony Mdrxb450Ap — biggest trade-off: It's wired only, with no active noise cancelling and sound isolation as its only isolation tool.
• JBL Tune 680NC — biggest strength: Adaptive Noise Cancelling with Smart Ambient, JBL Pure Bass plus Spatial Sound, and up to 76 hours of battery life with ANC off.
• JBL Tune 680NC — biggest trade-off: It leans on Bluetooth 6.0 and the JBL Headphones app for most of its best features, and the charging cable isn't included.
• Who each pick is for: Sony for the student who wants plug-and-play bass and a built-in mic on a 3.5mm jack; JBL for the student who wants noise cancelling, long wireless sessions and app-level sound tuning.
The MDR-XB450AP is Sony's Extra Bass formula in its most stripped-down form. An Acoustic Bass Booster works alongside 30mm dynamic drivers and a 5 Hz–22 kHz frequency range, which is the spec sheet telling you low frequencies are the priority here, not flat reference accuracy. Impedance sits at 40 ohm and sensitivity at 102 dB, so it's efficient enough to run straight off a phone or laptop jack without a dongle or amp. If your listening is hip-hop, EDM, gaming soundtracks or movie scores, that tuning is exactly the point.
The practical case for it is simplicity. It's a wired 3.5mm headset with an in-line microphone and volume control, so calls and volume changes happen on the cable — no pairing menus, no battery percentage, no firmware. The 1.2m tangle-free Y-type cord is long enough to reach from a pocket to your ears, and the swivel design plus 165g weight make it easy to fold and toss in a bag between classes. Sony's free SmartKey App lets you customize what the in-line remote button does on either Apple or Android phones.
JBL Tune 680NC: Who It's For
The Tune 680NC is the opposite philosophy: pack in every modern convenience and let the bass ride on top of it. JBL Pure Bass Sound with custom 32mm drivers gives you the same low-end emphasis, and JBL Spatial Sound widens the stage so audio feels like it's coming from around you rather than straight at you. There's also a Hi-Res path — the included USB-C to 3.5mm analog cable lets you go wired for more detail when you want it, which is a nice escape hatch from Bluetooth.
The headline feature is Adaptive Noise Cancelling with Smart Ambient. It adjusts automatically to shut out distractions, while Ambient Aware lets outside sound back in and TalkThru lets you hold a conversation without removing the headphones — both managed in the JBL Headphones app. That app also handles Personi-Fi 3.0, which shapes sound to your hearing profile, plus EQ presets and Smart Ambient controls. Two beamforming mics with noise reduction handle calls, which matters if you take teleconferences or group calls in noisy places.
Battery is the other big story: up to 76 hours with ANC off and Bluetooth on, roughly 50 hours with ANC on, a 5-minute speed charge for about 5 more hours, and a full recharge in about two hours. Bluetooth 6.0 adds multi-point so you can pair two devices and switch between them — laptop to phone, tablet to phone — with lower latency for video. At 5.6 ounces with soft on-ear cups, a padded headband and a fold-flat design, it's built for all-day wear.
Who should skip it: anyone who wants zero setup and zero charging. The app is where the customization lives, the charging cable is not included, and a wired-only listener gains little from paying for ANC and Bluetooth. But for the student juggling a laptop, a phone and a noisy dorm, this is the more capable tool.
• Best for battery life → JBL Tune 680NC: up to 76 hours with ANC off, about 50 with ANC on, plus a 5-minute charge for roughly 5 hours.
• Best for noise control → JBL Tune 680NC: Adaptive Noise Cancelling, Ambient Aware and TalkThru, all app-controlled.
• Best for plug-and-play simplicity → Sony Mdrxb450Ap: a 3.5mm wired headset with in-line mic and volume — nothing to pair, nothing to charge.
• Best for calls on the move → JBL Tune 680NC: two beamforming mics with noise reduction for busy environments.
• Best for wired bass on a phone jack → Sony Mdrxb450Ap: Acoustic Bass Booster, 30mm drivers, 40 ohm, 102 dB sensitivity.
• Best for app-level sound tuning → JBL Tune 680NC: Personi-Fi 3.0, EQ presets and Spatial Sound in the JBL Headphones app.
• Best for portability → Sony Mdrxb450Ap: 165g with a swivel fold and a 1.2m tangle-free Y-cord.
• Best for switching between two devices → JBL Tune 680NC: Bluetooth 6.0 multi-point pairing.
If I were buying for a college student who wants deep bass and doesn't want to think about charging, pairing or apps, I'd buy the Sony Mdrxb450Ap. It does one job — wired Extra Bass with a mic — and does it without friction. I'd choose the JBL Tune 680NC instead if noise cancelling, long wireless battery life and app tuning matter more than simplicity, because those are features the Sony simply doesn't have. Neither is "better" in the abstract; the JBL is the more capable headphone, and the Sony is the more effortless one. For most students splitting time between a dorm, a library and a commute, the JBL's ANC and battery are the features you'll notice daily. Check the current price on Amazon before deciding, since that gap often settles the question.
how to pair sony extra bass headphones
The MDR-XB450AP is a wired headset, so there's nothing to pair — you plug the 3.5mm jack into your phone or laptop and it works. If you're thinking of Sony's wireless Extra Bass models, those pair through your phone's Bluetooth menu. This specific model is wired only.

what is deep bass in headphones
Deep bass is the low-frequency end of the audio range — the sub-bass and bass you feel as much as hear. Headphones designed for it, like these, use boosters and driver tuning to emphasize those frequencies. The Sony's range starts at 5 Hz and the JBL uses JBL Pure Bass Sound with 32mm drivers.

I can't cover JVC here — this comparison is between the Sony Mdrxb450Ap and the JBL Tune 680NC. For the JBL, you pair it through your phone's Bluetooth settings and manage it in the JBL Headphones app. For general wireless bass headphones, the pairing process is usually the same: enable Bluetooth, select the device, then confirm.
