If you want open-ear comfort and awareness of your surroundings for call center work, choose MOOR Black OpenWave Open; if you need an in-ear hook fit and longer stated case-supported playtime, choose UPUNAIS Ear Buds. MOOR is my pick for a call center user who prefers not to seal the ear canal, while UPUNAIS better suits someone who wants earbuds secured around the ears and tucked into the ear.
• MOOR’s biggest strength: an open-ear design, four microphones, ENC, and a stated 40 hours of total playtime with the charging case. Trade-off: it rests on the ear rather than sealing into it, so it is not the choice for someone seeking an in-ear fit.
• UPUNAIS’s biggest strength: flexible ear hooks, an in-ear structure, and up to 50 hours of playtime with the case. Trade-off: its in-ear design blocks the open-ear style of environmental awareness MOOR is designed to preserve.
• MOOR suits people who want to hear some surroundings while taking calls or listening.
• UPUNAIS suits people who prefer a hook-secured in-ear fit for workouts and everyday listening.
MOOR is designed for people who do not want an earbud pushed into the ear canal. Each earpiece weighs 12.7 grams and rests on the ear, a practical distinction for someone who expects to wear headphones through long call sessions. The open design may also make it easier to remain aware of nearby activity than a sealed in-ear style. That can matter when a workday includes moving between a desk, a shared space, and other tasks.
For call center use, the most relevant features are four microphones and ENC noise-cancelling technology, which the product information says is intended to filter environmental noise and support clear voice transmission. Those features make MOOR the more natural match for a shopper prioritizing calls and an open fit. Bluetooth 5.3 and a stated 10-meter Bluetooth range also suit wireless use around a desk, though the listed range is not a guarantee for every room or setup.
Its 16.2mm dynamic drivers are larger than UPUNAIS’s 12mm drivers, and the product description emphasizes bass, midrange, and treble reproduction. MOOR also claims 10–11 hours of music playback on a charge and up to 40 hours with the case. The case is wireless charging compatible, and the earbuds are rated IPX4 for sweat and splashes. Skip MOOR if you specifically want an in-ear seal and ear hooks to hold the earbuds in place.

The listed call feature is ENC, described as reducing background noise for clearer calls. The product information does not specify a microphone count, so I would not assume it has the same four-microphone arrangement listed for MOOR. It uses Bluetooth 6 and advertises a stable connection and low latency, while its stated wireless range is 10 meters. For someone moving around during calls or listening, the newer Bluetooth version is a useful specification to note, but it does not by itself promise a better call experience in every environment.
UPUNAIS has 12mm dynamic drivers and up to 50 hours of playtime using the charging case. Its case includes an LED display for checking the remaining battery level of the earbuds and case, a handy detail for planning a charging routine. The earbuds are IPX4 rated for sweat and light splashes. Skip UPUNAIS if you want an open-ear fit that leaves the ear canal unobstructed and is specifically designed to help you sense your surroundings.
• Best for an open-ear fit → MOOR Black OpenWave Open. It rests on the ear instead of using an in-ear structure.
• Best for ear hooks and a secure workout fit → UPUNAIS Ear Buds. Its flexible hooks are intended to help keep the earbuds in place during exercise.
• Best fit for call center workers who want open ears → MOOR. Its open design, four microphones, and ENC make it the more purpose-aligned option for this need.
• Best stated total playtime with the charging case → UPUNAIS. It lists up to 50 hours, compared with MOOR’s up to 40 hours.
• Best for listed microphone detail → MOOR. It specifies four microphones; UPUNAIS lists ENC but does not give a microphone count.
• Best for checking battery status on the case → UPUNAIS. Its LED display shows the remaining level for both earbuds and the case.
• Best for larger listed dynamic drivers → MOOR. Its drivers are 16.2mm, versus 12mm for UPUNAIS; driver size alone does not establish which one will sound better to every listener.
• Best for a stated Bluetooth version of 6 → UPUNAIS. MOOR lists Bluetooth 5.3. Both specify a 10-meter range.
Buying Considerations
Next, separate call features from general listening specifications. MOOR names four microphones and ENC; UPUNAIS names ENC but gives no microphone count. Both are described as supporting clearer calls, but the supplied specifications do not establish which one will sound clearer in your particular workspace. A noisy shared room, the position of the earbuds, and the call software you use can all affect practical results.
Battery figures also need a little context. MOOR lists 10–11 hours of music playback per charge and up to 40 hours with the case. UPUNAIS lists up to 50 hours with its case, while its battery information also gives an average life of five hours. Those figures use different descriptions, so they should not be treated as a direct measurement under identical conditions. If you need to monitor remaining charge, UPUNAIS’s LED display is a specific convenience; if you prefer MOOR’s open fit, its case-supported total remains substantial on paper.
Finally, consider the environment. Both models are IPX4 rated, with product information describing protection from sweat and splashes. That makes either relevant for ordinary workouts or light exposure to moisture, but it does not make either a waterproof choice for swimming. The phrase “best clip on earbuds for call center” may point a shopper toward an open-ear style, but MOOR is described as resting on the ear, not as a clip-on model. If you are searching for in ear headphones for call center use, UPUNAIS matches that fit description more closely. And despite the phrase “best rechargeable kids headphones for call center,” these specifications do not establish either product as a dedicated children’s headset; the listed age descriptions include adults and teens for both, with MOOR also listing kids.
My Verdict
MOOR is the more direct fit for someone who wants open-ear headphones and a stated four-microphone ENC system. UPUNAIS also lists ENC for calls, but does not specify a microphone count.
No. MOOR uses an open-ear design that rests on the ear without stuffing the ear canal. UPUNAIS has an in-ear structure with flexible hooks.
UPUNAIS lists up to 50 hours with its charging case, compared with MOOR’s up to 40 hours. MOOR also lists 10–11 hours of music playback per charge, while UPUNAIS gives an average battery life of five hours; those figures are described differently and are not directly equivalent.
Both are rated IPX4 for sweat and splashes. UPUNAIS specifically highlights its hook-secured fit for workouts, while MOOR’s open-ear design is described as suitable for activities including running, cycling, hiking, and workouts.
