How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the deepest, most physical bass punch for the smallest possible outlay and you never want to worry about charging, choose WXQDDA Heavy Bass in-Ear; if you need adaptive noise cancelling, a 55-hour battery and a cable-free life on planes and commutes, choose Black Emblem X3.
• WXQDDA Heavy Bass in-Ear — biggest strength: a wired 3.5 mm connection with a dynamic driver tuned specifically for heavy bass, so there is zero latency between what you press and what you hear.
• WXQDDA Heavy Bass in-Ear — biggest trade-off: it is a wired in-ear with passive sound isolation only, so you are tethered to your device and there is no active noise cancelling or battery.
• Black Emblem X3 — biggest strength: adaptive active noise cancelling plus 55 hours of playtime from a single charge, in a 120 g on-ear design with a built-in mic.
• Black Emblem X3 — biggest trade-off: it relies entirely on Bluetooth, so you need to keep it charged, and its 200 ms latency figure makes it a weaker pick for timing-critical play.
• Who the WXQDDA is for: listeners and gamers who want thumping bass on a wired connection with no battery management at all.
• Who the X3 is for: commuters, travellers and call-takers who want quiet, long battery life and no cable in the way.
The WXQDDA Heavy Bass in-Ear is a straightforward proposition: a wired in-ear with a dynamic driver and a 3.5 mm jack, built around the idea that bass should be felt, not just heard. The model number is WX058, the colour is black, and the noise control is listed simply as sound isolation — meaning the earbuds physically seal your ear canal rather than running any electronics to cancel sound. That is the whole design philosophy here. No battery, no pairing, no firmware. Plug in and go.
Because it is wired, latency is effectively a non-issue. The brand describes it as "no delay," and with an analogue connection that claim is structurally sound — there is no Bluetooth codec buffering audio on its way to your ears. That matters most in two scenarios: mobile gaming, where a lag between a sound cue and the visual is genuinely disruptive, and any kind of rhythm-based listening where you want the kick drum to land exactly when the beat says it should. The ergonomic in-ear fit and the compact, portable profile also make it a natural fit for the gym, running and outdoor use, where a dangling cable is less annoying than a headphone that slides off your head mid-set.
Who should buy it: anyone who wants heavy bass without a charging routine, who uses a device with a headphone jack (or a cheap adapter), and who values a secure in-ear seal for workouts. Who should skip it: if you fly often, work in a noisy open office, or take a lot of calls, the passive isolation and lack of a microphone make it the wrong tool. Wired also means your phone has to be within arm's reach.
The Black Emblem X3 is the opposite approach — it is a wireless on-ear headphone built for people who move through noisy environments all day. The headline feature is adaptive ANC that adjusts to its surroundings, which the brand frames around aeroplane roar, café chatter and gym noise. That is the exact use case where active cancelling outperforms passive sealing: constant low-frequency drone is what ANC is good at. The 120 g weight, adjustable headband and memory foam pads are clearly aimed at all-day wear, and the retro, silver-and-stainless-steel look is a deliberate style choice rather than a purely functional one.
The numbers back up the travel pitch. Fifty-five hours of battery life on a single charge, with USB-C quick charging, means you can leave the cable at home for a long trip. Bluetooth 5.3 is listed in the feature set (the spec sheet lists Bluetooth 5.4 under style, so treat the version as "modern Bluetooth either way") with a 10-metre range, and there is a built-in mic for calls on a phone or PC. The 40 mm dynamic drivers cover a 20 Hz–20,000 Hz range at 32 ohm impedance, which is a standard full-range tuning rather than a bass-cannon signature — the brand promises "deep, clear bass" alongside crisp highs, so expect balance rather than overwhelming low end.
Who should buy it: commuters, frequent flyers, students in loud libraries, and anyone who takes calls and wants one headset for phone, laptop and console. Who should skip it: competitive gamers who need the lowest possible latency response. The listed audio latency is 200 milliseconds, which is fine for music, podcasts and casual play but noticeable in fast, timing-sensitive games. Also skip it if you dislike charging things — every session depends on battery.
• Best for raw deep bass impact → WXQDDA Heavy Bass in-Ear. Its entire tuning and marketing is built around heavy bass, and an in-ear seal puts that low end directly against your eardrum.
• Best for battery life → Black Emblem X3, with 55 hours per charge and USB-C quick charging.
• Best for noise cancelling → Black Emblem X3. Adaptive ANC actively adjusts to your environment; the WXQDDA only isolates passively.
• Best for gaming with tight audio timing → WXQDDA Heavy Bass in-Ear. A wired 3.5 mm connection sidesteps the X3's 200 ms latency entirely.
• Best for travel and commuting → Black Emblem X3. Lightweight on-ear build, folding-friendly compact design and no cable to snag.
• Best for calls → Black Emblem X3. It has a built-in mic; the WXQDDA does not list one.
• Best for workouts → WXQDDA Heavy Bass in-Ear, thanks to the ergonomic, secure in-ear fit and sturdy construction.
• Best for fuss-free ownership → WXQDDA Heavy Bass in-Ear. Nothing to pair, nothing to charge, nothing to update.
If I had to pick one for myself, I would buy the Black Emblem X3. In my opinion, the combination of adaptive noise cancelling, 55 hours of playtime, a built-in mic and a 120 g on-ear frame covers far more of daily life — commuting, flights, calls, casual listening — than a wired in-ear can. That said, I would recommend the WXQDDA Heavy Bass in-Ear without hesitation to anyone who specifically wants wired, latency-free, bass-forward listening for gaming or the gym and does not want to think about charging. They solve different problems; match the problem you actually have.
Deep bass refers to the low-frequency end of the audio range — roughly the bottom of the 20 Hz–20,000 Hz spectrum. In practice it is the sub-bass and mid-bass you feel as thump and rumble: kick drums, basslines and cinematic effects. In-ear designs like the WXQDDA achieve it partly through the ear seal; the X3 relies on its 40 mm drivers and tuning.
How to connect jvc deep bass wireless headphones?
Sony's extra-bass models pair over Bluetooth the same way any wireless headphone does: hold the power or pairing button until the indicator flashes, then choose the device in your Bluetooth menu. If you would rather skip pairing altogether, the WXQDDA Heavy Bass in-Ear needs no connection step at all — it is a straight 3.5 mm plug-in.
Enable pairing mode on the headphones, then select them from your phone's Bluetooth list; the first connection is the slowest and later ones are automatic. Worth noting: the X3 pairs over Bluetooth 5.3-class connectivity, while the WXQDDA does not pair at all because it is wired.
