How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want earbuds that stay tucked flat against your ear for side-sleeping, meditation and long studio sessions, choose I love e iFecco Invisible Sleep Earbuds; if you need clip-on buds that keep you aware of the room while you run, stretch and flow, choose APZXTRK Open Ear Earbuds.
• I love e iFecco Invisible Sleep Earbuds — biggest strength: an ultra-low-profile in-ear shape with flexible silicone tips, so there is no hard shell digging into your ear when your head is pressed against a mat or pillow.
• I love e iFecco Invisible Sleep Earbuds — biggest trade-off: the in-ear silicone seal is passive isolation only, so it muffles the room rather than cancelling it, and the buds themselves run 4–6 hours before they need the case.
• APZXTRK Open Ear Earbuds — biggest strength: a C-shaped titanium alloy bridge that bends to fit and a half in-ear clip-on design, so nothing blocks your ear canal and you stay aware of your surroundings.
• APZXTRK Open Ear Earbuds — biggest trade-off: an open fit means almost no isolation from a noisy room, and the black plastic build is bulkier in feel than a tiny sleep bud.
• Who each pick is for: I love e iFecco suits side sleepers, meditators and anyone who wants sound pressed quietly into the ear; APZXTRK suits movers who want music with the room still audible.
I love e iFecco Invisible Sleep Earbuds are built around one idea: get the sound in without anything poking out. The enclosure is ABS with silicone tips, the color is a soft beige, and the whole thing sits in-ear as an ultra-low-profile bud. For yoga specifically, that matters more than it sounds. In a long savasana or a seated breathing practice, you are resting the side of your head against a mat, a bolster or the floor, and a normal earbud with a stem becomes a pressure point within minutes. These don't have that problem — the point of the design is all-night comfort without pressure.
The feature set backs up a calm, low-key practice. Bluetooth 6.0 keeps the wireless link stable at up to 10 meters, and there is a built-in microphone so you can take a call without pulling the buds out. Audio runs through a dynamic driver with a 20 Hz–20,000 Hz range, 50 ohm impedance and 105 dB sensitivity, which is a fairly easy load to drive from a phone. Noise control is passive — the silicone seal does the work, masking the room rather than erasing it. That is exactly what you want for a guided meditation or a slow playlist: the outside world gets pushed back, not cut off. Controls are touch-based, so there is no fumbling for a button mid-pose.
Battery is the honest trade-off. The buds themselves give 4–6 hours of continuous play, and the compact charging case adds 20+ hours on top. IPX6 means sweat and water splashes are fine, so a hot class or a home flow won't kill them.
APZXTRK Open Ear Earbuds: Who It's For
APZXTRK Open Ear Earbuds take the opposite approach. The earpiece is half in-ear, and the housing clips onto the ear rather than sealing into the canal. The bridge is a C-shaped titanium alloy piece that bends without losing its shape, which is how a single size is meant to fit different ears during workouts, work or travel. The color is black, the enclosure and case are plastic, and the listed item weight is 64 g. The carrying case is a compact 2.5 x 2.5 x 1.5 inches and weighs 1.5 ounces.
For yoga, the appeal is awareness. Because nothing seals your ear canal, you hear your own breath, the teacher's cues and the room around you while music or a podcast plays underneath. Passive noise cancellation is listed, but with an open clip-on design the honest reading is that it blocks very little — that is the point. If you practise outdoors, in a shared studio or on a run before class, that openness is a safety feature, not a flaw.
On the tech side, the sheet lists Bluetooth 6.0 in the marketing copy and Bluetooth 5.4 in the spec block, so treat the version claim loosely; either way it pairs automatically when you open the case and reaches about 33 feet. Audio is a dynamic driver with a 32 ohm impedance, 105 dB sensitivity, 20 Hz–20,000 Hz range and 60 ms latency. That low-ish latency figure matters if you watch video while you move. Touch controls handle playback. Battery is up to 6 hours per charge with a 1-hour recharge time, and the case charges over USB-C and shows real-time battery. The case is also quoted at over 30 hours of total playback in the description, though the headline bullet says 6 hours per charge — worth knowing before you plan a long trip.
I would buy these if you want music during a flow, a run or a commute while still hearing what is happening around you, and if you like the idea of a bendable bridge instead of silicone pushed into your ear. I would skip them if you want isolation for sleep, a quiet flight or a noisy gym, or if you want buds that vanish into your ear.
• Best for side sleeping and floor-based practice → I love e iFecco Invisible Sleep Earbuds, because the ultra-low-profile in-ear shape creates no pressure point against a mat or pillow.
• Best for staying aware of your surroundings → APZXTRK Open Ear Earbuds, since the open half in-ear clip design leaves the ear canal unblocked.
• Best for passive noise blocking → I love e iFecco Invisible Sleep Earbuds; the silicone seal muffles the room, whereas the open fit does very little blocking.
• Best for a secure, shape-adapting fit → APZXTRK Open Ear Earbuds, thanks to the C-shaped titanium alloy bridge that bends to your ear.
• Best for water and sweat resistance → I love e iFecco Invisible Sleep Earbuds, which carries an IPX6 rating; APZXTRK's sheet lists no IP rating.
• Best for low-latency video and calls → APZXTRK Open Ear Earbuds, with a listed 60 ms audio latency and a built-in mic.
• Best for all-night or multi-hour listening → I love e iFecco Invisible Sleep Earbuds, whose case adds 20+ hours on top of 4–6 hours per charge.
• Best for hot, sweaty sessions → I love e iFecco Invisible Sleep Earbuds, again on the strength of that IPX6 protection.
In my opinion, if your practice is mostly on the floor — savasana, yin, long seated breathing, or falling asleep with a podcast — buy the I love e iFecco Invisible Sleep Earbuds. The flat in-ear design, silicone tips, IPX6 rating and 20+ hour case are exactly what a mat-based routine asks for, and the 4–6 hour bud life is enough for any single session. I would pick the APZXTRK Open Ear Earbuds only if hearing the room is non-negotiable, or if you want clip-on comfort for running and commuting alongside your yoga. For pure yoga earbuds, the flat, sealed fit wins it for me.
how to pair lenovo yoga earbuds
Pairing is a generic Bluetooth process, not a brand-specific one, and it works the same way for these two. Take the earbuds out of the case, open your device's Bluetooth settings, and select the model name — APZXTRK's sheet lists "SK39" as the pairing name. The I love e iFecco model is listed under model number S8+, so look for that entry. Both support Bluetooth 6.0 in their feature lists, connect wirelessly with no jack, and reach roughly 10 meters for the I love e iFecco and 33 feet for the APZXTRK.
how to connect lenovo yoga earbuds
Connecting is automatic once paired. APZXTRK's description states that simply opening the case lets the buds pair, and both models are listed as compatible with iOS, Android, tablets and laptops. If a connection drops, confirm Bluetooth is on, keep the buds within range, and re-select the model name in your device list. Neither set uses a physical cable for audio — both are wireless-only.
how to reset lenovo yoga earbuds
Neither data sheet documents a reset procedure, so I won't invent one. The practical fix is to place the buds back in the charging case, forget the device in your phone's Bluetooth menu, then re-pair from scratch. APZXTRK's case shows real-time battery and recharges over USB-C, and I love e iFecco's case adds 20+ hours of power, so a full case charge before re-pairing is a sensible first step.
how to pair lenovo tws yoga earbuds
Same flow as any true wireless set. Charge both earbuds in the case first, then remove them so they power on together, open Bluetooth on your phone, and tap the model name — "SK39" for the APZXTRK, S8+ for the I love e iFecco. Keep the phone within about 10 meters and avoid pairing near other active Bluetooth devices. Touch controls on both handle playback once connected.
