• Fulext's biggest strength: a 2-in-1 fabric headband with 0.25-inch flat speakers, a control module positioned between the speakers so it won't press your ears, and a machine-washable, hypoallergenic build — genuinely made for lying down.
• Fulext's biggest trade-off: it's a headband first, so the sound is tuned for quiet, close listening rather than loud outdoor training, and the spandex band is doing most of the work of holding it in place.
• TANFESO's biggest strength: a true open-ear clip design that never enters the ear canal, IPX7 waterproofing, a touch-screen charging case, and a 0.18 oz per-bud weight that stays put through running and dance.
• TANFESO's biggest trade-off: no passive isolation at all — you hear everything around you by design — and a shorter two-month warranty compared with Fulext's two years.
• Who each is for: Fulext for sleepers, side sleepers and studio-yoga types who want audio without anything in or over the ear; TANFESO for runners, cyclists and outdoor yogis who need to hear the world while they move.
The Fulext headband is built around a very specific problem: how do you listen to something at night without a hard plastic bud digging into your ear when you roll onto your side? The answer here is a flat 0.25-inch speaker sitting inside a stretchy spandex band, with the control module placed in the middle between the speakers rather than over the ears. That single design choice is why I'd point side sleepers at this product before almost anything else in this category. Passive noise cancellation comes from the fabric itself, not from sealing your ear canal, so nothing gets painful and nothing falls out at 3 a.m.
It also pulls double duty as a sports headband. The braided cord and breathable mesh lining are meant to handle sweat, and the band covers your hairline, which is a small but real quality-of-life detail if you're moving through a flow and don't want strands in your face. Bluetooth 5.4 gives you a 15-metre range, and the built-in mic plus volume and track controls mean you can take a call without reaching for your phone. The claimed battery story is 2 hours to charge for up to 14 hours of talk or audio time, with an average life figure of 10 hours listed — either way, that covers a full night plus a morning session.
Who should skip it? If your priority is loud, punchy sound for outdoor running, this isn't that product. The fabric and the flat drivers are tuned for comfort and closeness, and the band isn't going to stay perfectly still through sprints the way a clip-on bud will. It's also a single-item package — headband, USB-C cable, manual — so there's no charging case to top it up on the go. In my opinion, buy it if you want one soft object that handles sleep, yoga and calls; look elsewhere if you want a sport-first earbud.
The TANFESO M100 takes the opposite approach: nothing touches your ear canal at all. Each bud weighs 0.18 oz and clips on with soft silicone hooks, wrapping around the ear rather than pushing into it. The brand calls it a bone conduction driver, and the whole point of that architecture is that ambient sound stays fully available to you. If you run or cycle near roads, this is the safety feature that matters more than any spec sheet number — you can hear a car coming while your music keeps playing.
The other headline feature is the charging case with a digital display and touch controls. Instead of guessing whether you've got power left, you get a readout, and you can tap the case to manage music and calls. The mic system is tuned to pick up your voice while cutting background noise, which is useful if you take calls mid-workout. Bluetooth 5.4 is on board here too, with a 10-metre range and auto on-and-connect when you pull the buds out of the case.
IPX7 waterproofing is the detail I'd underline for hot yoga, outdoor sessions or rainy runs — that's a genuine submersible rating, not just splash resistance. The ergonomic surround design is also specifically noted as staying on while wearing glasses, which is a real-world problem for a lot of clip-on designs. The trade-offs are honest ones: with no noise control at all, you will hear everything, so this is a bad pick for a noisy flight or a shared dorm room. The warranty is listed at two months, which is short, and the plastic housing won't feel as plush as a fabric band. I'd recommend it for movement and daylight, not for sleep.
Side-by-Side: Which Should You Choose?
• Best for sleep and side sleeping → Fulext Sleep Headphones — flat 0.25-inch speakers and a module that sits between the speakers, not under your ear.
• Best for yoga and studio sessions → Fulext Sleep Headphones — the band doubles as a sweat-and-hair headband, and it's machine washable.
• Best for running, cycling and dance → TANFESO Open Ear Earbuds — 0.18 oz per bud, silicone hooks, and a fit that holds through movement and glasses.
• Best for battery confidence → Fulext Sleep Headphones — 2-hour charge for up to 14 hours of play or talk, plus a stated 10-hour average.
• Best for charging convenience → TANFESO Open Ear Earbuds — a digital-display charging case with touch controls beats a bare USB-C cable.
• Best for weather and sweat → TANFESO Open Ear Earbuds — IPX7 waterproofing versus a washable but not waterproof fabric band.
• Best for blocking out a noisy room → Fulext Sleep Headphones — passive isolation from the fabric; the TANFESO has no noise control at all.
• Best for long-term peace of mind → Fulext Sleep Headphones — a two-year warranty against TANFESO's listed two months.
If I had to pick one, I'd buy the Fulext Sleep Headphones. In my opinion, the combination of a washable fabric band, flat speakers designed around side sleepers, a 15-metre Bluetooth 5.4 range and a two-year warranty makes it the more versatile object — it covers sleep, yoga and calls in a single piece, and it's the one I'd actually reach for at night. I'd choose the TANFESO only if my routine is genuinely outdoor: running, cycling or hot yoga where hearing traffic matters more than blocking noise, and where IPX7 waterproofing earns its place. Two different jobs, two different answers — pick the job you do most.
how to pair lenovo yoga earbuds
I can't speak to Lenovo's pairing steps, since neither product here is a Lenovo device. For the earbuds on this page, the process is the standard one: charge them, then enable Bluetooth on your phone and select the device from the list. The TANFESO buds auto-pair when you take them out of the case, while the Fulext headband pairs once from its control module.
how to connect lenovo yoga earbuds
Same caveat — that's a different brand, so I won't guess at its instructions. What I can tell you is that both products covered here use Bluetooth 5.4 and work wirelessly with no jack. The Fulext reaches about 15 metres and the TANFESO about 10 metres, so keep your phone reasonably close in either case.
how to reset lenovo yoga earbuds
I don't have reset steps for Lenovo models, and I'd rather not invent them. For the two products compared here, a practical reset is to remove the device from your phone's Bluetooth list, power the headphones off, then pair again from scratch. The Fulext headband's control module and the TANFESO case both handle power on and off.

Again, that's outside the scope of this comparison. If you're deciding between the products on this page instead, the practical difference is that the TANFESO is true wireless with a charging case and auto-connect, while the Fulext is a single wireless headband with a built-in mic and touch volume controls. Both pair the normal way through your phone's Bluetooth menu.
