How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want the longest single-charge playback and a wider Bluetooth range, choose Cillso Earbuds; if you need a per-bud battery readout and the longest total runtime with the case, choose TELKRO Earbuds.
• Cillso Earbuds — biggest strength: Up to 8 hours of playback on a single charge and a 15 m Bluetooth range, plus an IPX7 nano-coating rating for sweat, rain and splashes.
• Cillso Earbuds — biggest trade-off: The LED display is a single readout on the case, so you do not get a separate number for each earbud, and the total with the case tops out at 40 hours.
• TELKRO Earbuds — biggest strength: A dual digital display that tracks the charging case and each individual earbud separately, with up to 42 hours of total power with the case.
• TELKRO Earbuds — biggest trade-off: Only 6 hours of playback per charge and a 10 m Bluetooth range, and the spec sheet calls out protection against sweat and splashes rather than a full waterproof rating.
• Who each pick is for: Cillso fits the buyer who wants long single-charge sessions and a wider roaming range; TELKRO fits the buyer who wants to see exactly which part of the system is running low.
Cillso builds its case around stamina and signal. The H97 model runs Bluetooth 5.4 with a high-sensitivity antenna, and the brand's own numbers put power consumption 30% lower and signal stability 35% better than Bluetooth 5.3. In practice, that means fewer dropouts when you leave your phone on a desk and walk to the kitchen. The 15 m wireless range is the wider of the two here, which matters if you move around a lot while your device stays put.
On battery, a single charge gives you up to 8 hours and the case stretches that to 40 hours total. The case itself carries a 300 mAh cell and refills in about 1.5 hours over USB-C, while the case's own battery is listed at 32 hours of average life. The LED display on the case shows battery level and charging status in real time — useful, but it is one number for the whole system rather than a readout per earbud.
The fit story is the other half of the pitch. These are semi-in-ear buds with airflow technology meant to reduce ear canal pressure, medical-grade gel tips, and a very light build: 3.5 g per earbud and 32 g for the case. The case has a magnetic closure so the buds do not tumble out in a bag. Audio comes from 13 mm drivers with AAC/SBC codecs, a 20 Hz–20 kHz range, 32 ohm impedance and 110 dB sensitivity, and four ENC microphones that the brand says cut about 85% of background noise on calls. IPX7 nano-coating covers sweat, rain and splashes.
Buy it if you take long calls in noisy places, want the longest single-charge session of the two, or want a roomier Bluetooth range. Skip it if you specifically want to see the charge level of each earbud separately on the case.
TELKRO's Digital Pro 4 leads with its display. The dual digital readout tracks the charging case and each individual earbud, so you can see which side is draining faster instead of guessing from a single icon. If you have ever had one bud die twenty minutes before the other, that is the whole argument for this design.
Battery is where TELKRO pushes back on Cillso. You get up to 6 hours per charge, but the high-capacity case takes the total to 42 hours — two more than Cillso's 40. The case charges in about 1.5 hours over USB-C. Bluetooth 5.4 handles the connection with auto-pairing: pair once, then just open the case and it reconnects. The stated range is 10 m, which is shorter than Cillso's but still fine for a normal room, and the brand frames the chipset around low latency and stable transmission.
The audio side is a dynamic driver with 32 ohm impedance, 105 dB sensitivity and a frequency response starting at 20.2 Hz. TELKRO leans on tuning language here — deep bass balanced against crisp treble, plus an acoustic structure aimed at clear voice calls and noise isolation from the ergonomic fit. Controls are touch-based and clearly mapped: single tap for play, pause and answering calls; double-tap right for next track, left for previous; triple-tap right to raise volume, left to lower it. The buds are small and light enough for a pocket, and they are built to handle sweat and water splashes for runs, gym sessions and commutes. The finish here is white, and the box includes a cable, eartips, a protective case, a user manual and the wireless charging case.
Buy it if you want per-bud battery visibility, the longest total runtime with the case, or a straightforward tap-control layout. Skip it if you need a longer single-charge session or a wider Bluetooth range.
• Best for a single long session → Cillso Earbuds: up to 8 hours per charge versus 6 hours on the TELKRO.
• Best total battery with the case → TELKRO Earbuds: 42 hours versus 40 hours.
• Best battery visibility → TELKRO Earbuds: dual digital display covers the case and each earbud; Cillso's LED shows one combined status.
• Best Bluetooth range → Cillso Earbuds: 15 m versus 10 m.
• Best for sweaty or rainy workouts → Cillso Earbuds: IPX7 nano-coating; TELKRO is described as resistant to sweat and splashes.
• Best for call clarity in noise → Cillso Earbuds: four ENC microphones with a stated 85% background-noise reduction.
• Best for a light, low-pressure fit → Cillso Earbuds: 3.5 g per bud, semi-in-ear shape with airflow tech and gel tips.
• Best for the simplest control scheme → TELKRO Earbuds: tap counts are spelled out for every command, which is easier to memorize than a general touch panel.
• Best for a clean white finish → TELKRO Earbuds: Cillso's listing is an ebony/black colorway.
In my opinion, the Cillso Earbuds are the better all-round pick for most people. Eight hours per charge, a 15 m range, four ENC mics and an IPX7 rating cover the situations where cheap earbuds usually let you down — long calls, sweaty runs, and walking away from your phone. The TELKRO Digital Pro 4 is the smarter buy if battery anxiety is your main gripe: the dual display tells you exactly what is low, and 42 hours total keeps you away from a charger for longer. If I had to pick one for myself, I would take the Cillso. Before you decide, check the current price on Amazon, since that is the one variable that can flip this call.
are earbuds considered electronics
Yes. Wireless earbuds are consumer electronics — both of these run Bluetooth 5.4, use touch controls, charge over USB-C and contain lithium batteries. That also means they are subject to normal electronics handling rules and airline battery policies.
can you connect earbuds to a tv
Yes, if your TV has Bluetooth. Both the Cillso and TELKRO pair as standard Bluetooth devices, and both are listed as compatible with phones, tablets and laptops. If your TV lacks Bluetooth, you would need a separate Bluetooth transmitter.
should i get black or white earbuds
That is purely a looks-and-maintenance call. The Cillso comes in an ebony/black finish; the TELKRO Digital Pro 4 in this listing is white. Black hides scuffs and earwax better; white shows dirt sooner but reads as cleaner on a desk.
do these earbuds show how much battery is left
Yes, both do — but differently. Cillso uses a single LED display on the case showing battery level and charging status. TELKRO uses a dual digital display that tracks the case and each individual earbud separately.
