How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want all-day battery life in an open-ear design that keeps you aware of traffic and your surroundings, choose QJF Open Ear; if you need in-ear noise isolation with a dual LED display that tracks both the case and each earbud, choose TELKRO Earbuds.
• QJF Open Ear — biggest strength: open-ear air-conduction fit that stays put during runs and cycling, plus a claimed 50-hour total playtime and Bluetooth 5.4 with a 15-meter range.
• QJF Open Ear — biggest trade-off: because nothing seals your ear canal, you get less passive isolation, so loud environments will fight your music.
• TELKRO Earbuds — biggest strength: in-ear dynamic drivers with environmental noise cancellation and a smart dual LED display that shows charge for the case and each bud separately.
• TELKRO Earbuds — biggest trade-off: 6 hours per charge and up to 42 hours total is less endurance than the QJF set, and the 10-meter Bluetooth range is shorter.
• Pick QJF Open Ear if you run, ride, or drive and want your ears open. Pick TELKRO Earbuds if you want a sealed, immersive listen and a battery readout you can actually see.
The QJF Open Ear is built around one idea: keep your ears unplugged. The earpiece shape is open-ear, each bud weighs 6.2 grams, and the housing is lightweight PC material with an IP54 water-resistance rating. In practice that means you can run, cycle, or lift without a bud popping loose, and you can still hear a car behind you or a coworker calling your name. For anyone who has ever felt uneasy wearing sealed buds on a busy road, that awareness is the whole point.
On the technical side, QJF uses Bluetooth 5.4 with a claimed 15-meter stable transmission range and auto-pairing the moment you lift the buds out of the case. Battery is the headline: 50 hours of total playtime with the charging case, recharged over USB-C. The spec sheet also lists active noise cancellation, a 16-ohm impedance, 103 dB sensitivity, and a 20 Hz–20,000 Hz frequency range. Controls are touch-based and cover play/pause, track skipping, volume, calls, and voice assistants. A two-year manufacturer warranty is listed.
TELKRO Earbuds: Who It's For
The TELKRO Digital Pro 4 takes the opposite approach. These are traditional in-ear buds with a plastic housing in white, a dynamic driver, 32-ohm impedance, 105 dB sensitivity, and a frequency response starting at 20.2 Hz. The brand markets a Hi-Fi balance of deep bass and crisp treble, and the in-ear seal is what makes that possible. Environmental noise cancellation is listed, which is the passive-plus-software kind of isolation you get from a good fit rather than a full over-ear ANC system.
The feature that gives this page its name is the display. A smart dual LED panel shows real-time battery level for the charging case and for each individual earbud, so you're never guessing whether the left bud is about to die. Battery is 6 hours on a single charge with up to 42 hours total from the case, and the case charges in about 1.5 hours over USB-C. Bluetooth 5.4 handles the connection with auto-pairing after first setup and a stable range up to 10 meters. Touch commands are clearly mapped: single tap for play/pause and calls, double-tap left or right for track skipping, triple-tap left or right for volume. Sweat and splash resistance is included, and the package lists a cable, eartips, a protective case, a user manual, and the wireless charging case. Warranty is one year.
Who should buy it: commuters, office workers, students, and anyone who wants an immersive listen with visible battery status and a compact case that disappears into a pocket. Who should skip it: if situational awareness matters more than isolation, or you want the longest possible stretch between charges, the QJF set fits better.
Side-by-Side: Which Should You Choose?
• Best for battery life → QJF Open Ear. Up to 50 hours total versus up to 42 hours on the TELKRO set, with 8 hours per charge versus 6.
• Best for immersive sound and isolation → TELKRO Earbuds. In-ear dynamic drivers with environmental noise cancellation put you inside the music.
• Best for seeing your battery at a glance → TELKRO Earbuds. The dual LED display reads out the case and each earbud separately; QJF relies on a display case without per-bud readouts specified.
• Best for running and cycling outdoors → QJF Open Ear. IP54, 6.2 g per bud, and an open fit that won't seal sweat in or block traffic noise.
• Best for commuting and calls in busy places → TELKRO Earbuds. The seal and voice-call tuning are designed for exactly that environment.
• Best for wireless range → QJF Open Ear. 15 meters versus 10 meters, useful if you leave your phone on a bench or desk.
• Best for warranty coverage → QJF Open Ear. Two years versus one year from TELKRO.
If I were buying one pair for myself, I'd take the QJF Open Ear. The 50-hour total playtime, the 15-meter Bluetooth range, the IP54 rating, the sub-7-gram buds, and the two-year warranty line up with how most people actually use earbuds — long days, outdoor movement, and not wanting to think about charging. The open-ear format is also the safer choice for anyone running or riding near traffic.
That said, if your priority is sound isolation and you want a battery readout you can see before you leave the house, the TELKRO Earbuds are the smarter pick. The dual LED display and in-ear seal are genuinely useful features, and the 42-hour total life is still plenty for most weeks. Just know you're trading awareness and endurance for immersion and visibility.
FAQ
are earbuds considered electronics
can you connect earbuds to a tv
Only if your TV supports Bluetooth audio output or you use a Bluetooth transmitter. Both the QJF Open Ear and TELKRO Earbuds use standard Bluetooth 5.4, so pairing works the same way as with a phone. Bluetooth 5.4 also helps with latency, which is why these are a reasonable choice for late-night viewing.
should i get black or white earbuds
That's purely cosmetic here. The QJF Open Ear is listed in black, while the TELKRO Digital Pro 4 is listed in white. Pick based on how the buds will look against your hair, helmet, or gym kit — there's no performance difference tied to color in either spec sheet.
The QJF Open Ear. It's IP54 rated, weighs 6.2 g per bud, uses an open-ear fit that won't work loose mid-stride, and lets you hear approaching traffic. The TELKRO buds resist sweat and splashes too, but the sealed in-ear fit is better suited to commuting and indoor listening.
