How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want maximum playtime, active noise cancelling and a proper over-ear fit, choose SUNJOM Freepods Over-Ear; if you need a lightweight neckband you can wear for workouts and gaming with deep bass and EQ control, choose Lsolrophon Neckband.
• SUNJOM Freepods Over-Ear — biggest strength: 120 hours of playtime, active noise cancelling and a 40mm dynamic driver in a full over-ear design with a 3.5mm wired backup.
• SUNJOM Freepods Over-Ear — biggest trade-off: It's the bulkier of the two at 240 g, so it's a sit-down, commute and travel headphone rather than something you'd want bouncing around during a run.
• Lsolrophon Neckband — biggest strength: A 14mm copper ring driver tuned for deep bass, six EQ modes and IPX7 sweat protection in a neckband that stays put during workouts.
• Lsolrophon Neckband — biggest trade-off: It's in-ear only, with no wired option and no active noise cancelling — isolation comes from the silicone tips, not from electronics.
• Pick SUNJOM if you want one headphone for long flights, work-from-home days and movie nights.
• Pick Lsolrophon if you want something light for the gym, gaming sessions and all-day wear around your neck.
The Freepods Over-Ear is built around two ideas: listening for a very long time, and shutting the world out while you do it. SUNJOM rates the battery at 120 hours, and a full charge takes about 4 hours. That's the kind of number that matters if you're the person who always forgets to plug things in — you can go weeks of normal use without thinking about a cable. Active Noise Cancelling is on board too, and SUNJOM describes it as cutting noise by up to 98%, which is the sort of claim that in practice means engine drone, air conditioning and office chatter get pushed well into the background.
The sound hardware is a 40mm dynamic driver with a 20 Hz – 20,000 Hz frequency range, 32 ohm impedance and 120 dB sensitivity. That's a full-size driver, and full-size drivers are exactly what you want for deep bass — a bigger diaphragm moves more air, which is why the low end on an over-ear design like this tends to have more weight and physical presence than a small in-ear can manage. The enclosure mixes leather, metal and plastic with oval earcups, and the protein foam padding is designed to seal around your ears rather than press on them. There's also a 3.5mm jack, so if the battery ever runs dry you can plug in and keep listening.
Who should buy it: frequent travellers, remote workers, students and anyone who wants one pair of headphones to cover music, movies, TV and calls. Who should skip it: runners and gym-goers who want something that disappears on their head — at 240 g with a full headband, this is not that product.
Lsolrophon Neckband: Who It's For
The Lsolrophon Neckband takes the opposite approach. Instead of covering your ears, it hangs around your neck and feeds two magnetic metal earbuds into your ear canals. The result is a much lighter thing to carry, and the ergonomic in-ear shape plus soft silicone tips are designed to stay locked in during movement. IPX7 water resistance backs that up — sweat and rain are explicitly covered, which is the clearest signal that Lsolrophon expects you to wear these while training.
On the audio side, the headline is a 14mm copper ring driver that Lsolrophon specifically describes as producing deep bass and full stereo sound. Fourteen millimetres is a large driver for an in-ear bud, and combined with the sealed fit of silicone tips it's a design aimed squarely at bass-forward listening. There are also six preset EQ modes, which is the practical part: if the default tuning isn't to your taste, you can shift the balance instead of living with it. For anyone who cares about low end, that flexibility matters more than a single fixed sound signature.
Battery life is rated at 100 hours from a 900mAh cell, with a full USB-C charge taking around 3.5 hours and a 5-minute top-up giving roughly 2.5 hours of listening. Bluetooth 5.4 is on board, and there's a low-latency game mode rated at 20ms — useful if you're watching video or playing games and don't want audio drifting behind the picture. Dual HD microphones with ENC handle calls, and physical buttons cover music, calls and volume.
Who should buy it: gym users, runners, commuters who want something light, mobile gamers, and anyone who prefers the feel of earbuds over a headband. Who should skip it: people who want active noise cancelling for flights, or who want the option of a wired connection when the battery dies.
• Best for deep bass from a larger driver → SUNJOM Freepods Over-Ear — a 40mm dynamic driver moves more air than any in-ear, which is what gives over-ear bass its weight.
• Best for bass you can tune → Lsolrophon Neckband — the 14mm copper ring driver plus six EQ modes lets you push the low end where you want it.
• Best for battery life → SUNJOM Freepods Over-Ear — 120 hours versus 100 hours, with a longer 4-hour charge but a much bigger reserve.
• Best for quick top-ups → Lsolrophon Neckband — a 5-minute charge returns about 2.5 hours of playback, which is genuinely useful before a workout.
• Best for noise cancelling → SUNJOM Freepods Over-Ear — active noise cancelling plus an ambient aware mode; the Lsolrophon relies on passive in-ear sealing alone.
• Best for workouts and sweat → Lsolrophon Neckband — IPX7 water resistance and a magnetic neckband design versus an over-ear headphone with no water rating listed.
• Best for gaming and video → Lsolrophon Neckband — the 20ms low-latency mode is built for exactly that.
• Best for flights, movies and long sessions → SUNJOM Freepods Over-Ear — the over-ear seal, protein foam padding and 3.5mm wired option suit long, stationary listening.
In my opinion, the SUNJOM Freepods Over-Ear is the one I'd buy if I could only pick one. A 40mm dynamic driver in a sealed over-ear shell, active noise cancelling, 120 hours of playtime and a 3.5mm fallback is a combination that covers almost everything a normal listener does in a week. I'd only steer you to the Lsolrophon Neckband if your priority is bass you can shape with EQ, sweat resistance and portability — that's a genuinely different job, and for the gym it's the better tool. For deep bass at home, on a plane or at a desk, I'd take the over-ear.
what headphones have deep bass
For deep bass, look at driver size and fit first. The SUNJOM Freepods Over-Ear uses a 40mm dynamic driver with a 20 Hz – 20,000 Hz range, and its over-ear seal helps low frequencies land with more weight. The Lsolrophon Neckband uses a 14mm copper ring driver that Lsolrophon tunes specifically for deep bass.
what are headphones with good bass
"Good bass" usually means a driver large enough to move air and a fit that seals properly. Over-ear designs like the SUNJOM Freepods Over-Ear have the size advantage, while in-ear designs like the Lsolrophon Neckband get an assist from silicone tips sealing your ear canal. The Lsolrophon also adds six EQ modes if you want to adjust the balance.
what is bass in headphones
Bass is the low-frequency part of the audio range — roughly the bottom end of the 20 Hz – 20,000 Hz spectrum both headphones cover. It's what you feel in kick drums, basslines and movie effects. A larger driver and a tighter seal generally produce more of it.
what are earbuds with good bass
The Lsolrophon Neckband is the earbud-style option here: a 14mm copper ring driver, magnetic metal earbuds, six EQ modes and IPX7 sweat protection. If you'd rather have a full over-ear design with active noise cancelling and 120 hours of playtime instead, the SUNJOM Freepods Over-Ear is the alternative — check the current price on Amazon before deciding.
