If you want a traditional over-ear headphone with big drivers, a hard carry case and a folding frame for commuting, travel and movie nights, choose YUSONIC BS660; if you need an open-ear sport headband that keeps your ears free to hear traffic while you run, sweat hard and lie down, choose NDEJFIE Sport Headband Headphones. Both lean on touch controls, but they use them for completely different jobs — one is a listening-first headphone, the other is a workout-first wearable.
• YUSONIC BS660 — biggest strength: dual 40mm dynamic drivers in a foldable over-ear shell, plus an independent power key that makes pairing and reconnecting fast, and a hard Yusonic carry case in the box.
• YUSONIC BS660 — biggest trade-off: it's a closed over-ear design with sound isolation rather than awareness, so it's the wrong pick if you need to hear cars, coworkers or your surroundings.
• NDEJFIE Sport Headband Headphones — biggest strength: an open-ear, air-conduction headband with a sweat-wicking elastic band, 12 hours of playback and touch gestures split across left and right sides.
• NDEJFIE Sport Headband Headphones — biggest trade-off: open-ear sound deliberately leaks in ambient noise, so it's not the tool for deep-bass listening or blocking out a noisy room.
• Who each is for: YUSONIC BS660 for commuters, students, travelers and movie/gaming listeners; NDEJFIE for runners, cyclists, walkers, gym-goers and anyone who wants audio at night without sealing their ears.
The BS660 is built around one idea: give a daily listener a proper over-ear experience without overcomplicating it. Two 40mm dynamic drivers handle the audio, and the stated frequency range runs from 20Hz to 20KHz with 32Ω impedance and 93dB sensitivity. In practice that combination — large drivers plus a full-size, closed ear cup — is the recipe for the layered, bass-forward sound the specs describe, and it's what makes this headphone a natural fit for music, games and films rather than podcasts alone.
The control layout is the part I find most interesting. YUSONIC pairs an invisible touch panel for track, volume and call handling with a separate physical power key. That sounds like a small detail, but a dedicated switch means on/off and pairing aren't buried inside a gesture system — you tap for playback, you press for power. Bluetooth 5.3 covers pairing and reconnection, with a claimed 33-foot range, and the built-in microphone supports one-touch hands-free calls, which is the feature that makes it workable for online classes, meetings and voice chats.
Comfort and portability are where the design earns its keep. The ear cushions use breathable PU leather over high-elastic sponge, the headband adjusts, and the ear cups rotate 60° and 90° in both directions before folding flat into the included hard case. Weight lands around 143–148g, and a 400mAh battery is rated for over 20 hours of continuous playback per charge, with a full charge taking about 1.5 hours. If you use it three hours a day, that's roughly a week between charges. There's also a 3.5mm jack and a 1.2m cable, so it can run wired when you want.
NDEJFIE Sport Headband Headphones: Who It's For
The NDEJFIE headband is a different species of product. Instead of cups that seal around your ears, it uses an ultra-thin HD stereo air-conduction speaker built into a fabric band that sits across your head, with the drivers firing toward your ears rather than into them. That open-ear approach is the whole point: you get clear, layered sound while your ear canals stay uncovered, so traffic, footsteps and voices still reach you. For running, cycling, hiking and walking, that awareness isn't a bonus — it's the reason to buy this instead of a sealed headphone.
The band itself is the second half of the design story. It's an elastic, breathable, sweat-wicking headband, and the spec sheet specifically calls out that it keeps sweat from running down into your eyes mid-workout. Because there are no cups pressing on your ears, it also works with glasses and hearing aids without squeezing them, and the "stays in place while sleeping" claim tells you how low-profile the fit is meant to be. That's a genuinely unusual combination: one device for gym sessions and for lying in bed.
Controls here are all touch, but split intelligently across the two sides. The left side handles volume with a forward/back swipe, a single tap for answering or hanging up, and a two-second hold to trigger your voice assistant. The right side swipes for previous/next track, taps to play or pause, and takes five quick taps to factory reset. Power is a five-second hold, and pairing means finding "Ultra X" in your Bluetooth list — it reconnects automatically afterward. Bluetooth 5.4 is the newest version in this comparison, with a stated range up to 15 meters, and the battery is rated for 12 hours per charge. Active noise cancellation is listed as the noise-control type, though with an open-ear design you should read that as processing rather than isolation.
Buy it if you run, cycle, hike, lift or walk outdoors and want your ears open to the world, you sweat heavily, you wear glasses or hearing aids, or you want something you can wear in bed without a cup digging into your ear. Skip it if you want deep, sealed bass, you need to block out a loud office or plane cabin, or you'd rather have a physical power button than a long-press gesture.
• Best for sound depth and bass → YUSONIC BS660. Dual 40mm dynamic drivers in a closed over-ear shell are simply the better platform for full-bodied audio.
• Best for running and outdoor safety → NDEJFIE Sport Headband Headphones. The open-ear, air-conduction design keeps you aware of traffic and surroundings.
• Best for battery life → YUSONIC BS660. Over 20 hours versus 12 hours per charge, with a 1.5-hour charge time and a 400mAh cell.
• Best for heavy sweaters and gym work → NDEJFIE Sport Headband Headphones. The sweat-wicking elastic band is purpose-built to stop sweat reaching your eyes.
• Best for travel and packing → YUSONIC BS660. Bidirectional folding, rotating ear cups and a hard carry case make it a bag-friendly item.
• Best for newer wireless tech → NDEJFIE Sport Headband Headphones. Bluetooth 5.4 with auto-reconnect and a stated 15-meter range edges ahead of 5.3.
• Best for glasses and hearing-aid wearers → NDEJFIE Sport Headband Headphones. No ear cups, no pressure, no interference.
• Best for calls and meetings → YUSONIC BS660. A built-in HD microphone with one-touch hands-free calling suits classes, work calls and voice chat.
• Best for wired backup → YUSONIC BS660. It includes a 3.5mm jack and a 1.2m cable; the NDEJFIE is wireless only.
In my opinion, most people shopping between these two should buy the YUSONIC BS660. It's the more versatile object: it sounds fuller thanks to those 40mm drivers, it folds into a hard case, it gives you a real power button alongside touch controls, it lasts nearly twice as long per charge, and it can fall back to a cable. The NDEJFIE headband is the better product for exactly one job done very well — open-ear sport and sleep listening — and if that's your job, nothing on the YUSONIC side replaces it. Buy the headband if you're a runner, cyclist or glasses wearer who values awareness over isolation. Everyone else: take the BS660.
how to disable touch controls on headphones
There's no universal switch — it depends on the model and firmware. On the YUSONIC BS660, touch handles track, volume and calls while a separate physical key controls power, so you can't turn the touch layer off without losing those functions. On the NDEJFIE headband, touch is the only control method, and the only reset-style gesture listed is five quick taps on the right side to factory reset, which clears settings rather than disabling touch.
why are my headphones controlling my phone
Because the touch panel or buttons send standard Bluetooth control signals — play/pause, track skip, volume and call answer — that your phone interprets as media commands. Both products here do this by design: the BS660's hidden touch panel and dedicated power key, and the NDEJFIE's left- and right-side swipe and tap gestures. If a gesture is triggering something you didn't intend, the practical fix is to change or disable the media control in your phone's Bluetooth settings for that device.
what is touch control on headphones
Touch control replaces physical buttons with a capacitive panel or gesture zones on the ear cup or band. On the YUSONIC BS660 it's an invisible panel for track, volume and call operations, paired with a separate power switch. On the NDEJFIE Sport Headband Headphones it's split by side: left swipes for volume, single tap to answer or hang up, two-second hold for the voice assistant; right swipes for tracks, tap to play or pause, five taps to reset.
do I need touch controls for running headphones
No — but they help. With the NDEJFIE headband, all controls sit on the band itself, so you never fumble for a phone mid-run, and the open-ear design keeps you aware of traffic. If you'd rather have a physical button for power and don't need ear-free awareness, the YUSONIC BS660's hybrid approach — touch for playback, a real switch for power — is the more forgiving option.
