How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the bass-forward, app-tunable wireless experience of a well-known Extra Bass line, choose Sony XB950B1; if you need marathon battery life and a wired-or-wireless studio-style kit, choose Keenso Over Ear. These two are rarely shortlisted together, and that is exactly why the comparison is useful: they solve deep bass in completely different ways.
• Sony XB950B1 — biggest strength: Purpose-built "EXTRA BASS" tuning with app-based sound control, Bluetooth + NFC pairing, and a 3.5 mm jack as a wired fallback.
• Sony XB950B1 — biggest trade-off: 18 hours of playback and roughly 4 hours to recharge, which is modest next to the Keenso's 60-hour claim.
• Keenso Over Ear — biggest strength: Bluetooth 5.4 with a claimed 1–3 second pairing time and up to 60 hours of continuous playback, plus a generous accessory bundle (two 3.5 mm cables, a 6.35 mm adapter, a 2-in-1 sound adapter, and a USB power cable).
• Keenso Over Ear — biggest trade-off: It is a mixed wired/wireless studio-style headset with a 90-day manufacturer warranty, no app control, and no active noise cancellation listed.
• Who Sony XB950B1 is for: listeners who want deep bass they can shape from a phone app and who value a mainstream wireless feature set with NFC.
• Who Keenso Over Ear is for: DJs, home-studio tinkerers, and long-session listeners who want maximum runtime and every adapter they might need in the box.
The XB950B1 is the more "consumer electronics" of the two. It is an over-ear, around-ear design in black with a plastic enclosure and a matching carrying case, weighing about 9.9 ounces. It runs Bluetooth 4.2 with a stated range of 10 meters, and it also supports NFC, which is the tap-to-pair convenience you rarely see on budget wireless headphones anymore. There is a 3.5 mm jack too, so you can go wired when the battery is drained or when you want zero wireless latency.
What it does best, in my opinion, is give a bass-first listener control. Sony's Headphones Connect app is the centerpiece here — it is the control method for the sound, not a novelty extra. With a dynamic driver and a 20Hz–20kHz frequency range, the hardware is mainstream, but the app is what lets you push the low end to your taste rather than accepting a fixed factory curve. The 32-ohm impedance and 18-hour battery life are reasonable for commuting, office listening, and everyday streaming. A built-in mic handles calls wirelessly, and active noise cancellation is listed as a noise-control feature.
Who should buy it: someone who wants one pair of over-ear headphones for music, calls, and travel, who will actually open the app and tune the bass, and who likes the reassurance of a recognizable brand name and a carrying case.
Who should skip it: anyone who needs extreme runtime between charges, who wants a hardwired monitoring setup with adapters for studio gear, or who dislikes app-dependent tuning. If you want your sound decisions made on the hardware rather than in software, this is not the design for you.
The Keenso Over Ear is the utility player. It is built as an over-ear headset with soft memory foam earcups wrapped in protein leather and a skin-friendly finish, plus an adjustable headband and 90° rotating earcups. That rotating design is the tell: this is a headset meant for monitoring — you swivel one cup off your ear to hear the room while your music or mix keeps playing, which is standard practice for DJs and studio work.
The spec sheet reads like a connectivity toolkit. Bluetooth 5.4 is a newer wireless generation than the Sony's 4.2, with a claimed pairing time of 1–3 seconds after powering on and a 10-meter (33-foot) effective range. Battery life is claimed at up to 60 hours of continuous playback from a built-in 600mAh lithium-ion battery, charged over Type-C. You also get a microSD card slot that accepts cards up to 32GB (card not included) — meaning it can play files directly without a phone at all. Drivers are 40mm with a 20Hz–20kHz response, and the box includes two 3.5 mm cables, a 6.35 mm adapter, a 2-in-1 sound adapter, and a USB power cable, so it plugs into everything from a laptop to a mixing console.
One caveat worth stating plainly: the product information lists the ear placement as "In Ear" and the connectivity technology as "ethernet," which contradicts the over-ear description and Bluetooth 5.4 spec elsewhere in the same listing. Treat the bullet points and description as the more detailed source, but know that the data here is internally inconsistent. Warranty is 90 days from the manufacturer.
Who should buy it: DJs, podcasters, home recordists, and anyone who wants a single headset that works wirelessly, wired, and even from a memory card — with runtime measured in days rather than hours.
Side-by-Side: Which Should You Choose?
• Best for bass tuning control → Sony XB950B1. The Headphones Connect app is the differentiator; you shape the low end yourself.
• Best for battery life → Keenso Over Ear. Up to 60 hours claimed versus 18 hours on the Sony.
• Best for studio and DJ use → Keenso Over Ear. 90° rotating earcups, two 3.5 mm cables, a 6.35 mm adapter, and a 2-in-1 sound adapter.
• Best for wireless convenience → Sony XB950B1. Bluetooth plus NFC tap-pairing and a carrying case for travel.
• Best for phone-free playback → Keenso Over Ear. The microSD slot (up to 32GB, card not included) plays files directly.
• Best for calls → Sony XB950B1. It explicitly lists a built-in mic for wireless calls.
• Best for newer Bluetooth → Keenso Over Ear. Bluetooth 5.4 versus the Sony's 4.2.
• Best for warranty comfort → Sony XB950B1. Keenso's manufacturer warranty is only 90 days.
If I were buying one pair for everyday music, commuting, and calls, I would take the Sony XB950B1. In my opinion, the app-controlled EXTRA BASS tuning, NFC pairing, built-in mic, active noise cancellation, and carrying case make it the more complete wireless headphone for a normal listener — and the 3.5 mm jack covers you when the battery runs down.
I would only pick the Keenso Over Ear if my priority were runtime and hardware flexibility rather than tuning. For DJ work, studio monitoring, or long off-grid sessions, the 60-hour claim, rotating earcups, and full adapter bundle are genuinely more useful than app control. Check the current price on Amazon for both before deciding, since value shifts over time.
FAQ
how to pair sony extra bass headphones
how to connect sony extra bass headphones
You have two routes on the XB950B1: wireless over Bluetooth 4.2 within a 10-meter range, or wired through the 3.5 mm jack. Once paired, the Sony Headphones Connect app is where you adjust sound settings, and the built-in mic handles calls without unplugging anything.
how to connect jvc deep bass wireless headphones
That is a different brand, so the steps differ — but the general pattern is the same as any Bluetooth headset: power on, enter pairing mode, then select the headphones in your device's Bluetooth settings. Check that brand's own instructions, since pairing buttons and app support vary by model.
what is deep bass in headphones
Deep bass refers to how well a headphone reproduces the lowest audible frequencies — both the Sony and the Keenso list a 20Hz–20kHz frequency range, so both reach down to 20Hz on paper. What separates them in practice is tuning: the Sony leans into an "EXTRA BASS" voicing with app adjustment, while the Keenso relies on its 40mm drivers and a more neutral studio-style presentation.
