• MKJ Cisco Headset — biggest strength: a wired RJ9 connection built specifically for a long list of Cisco desk phones, with noise-cancelling mic, over-ear comfort and a reinforced cord meant for constant office use.
• MKJ Cisco Headset — biggest trade-off: it is tethered to the phone by a cable, and it only works with the listed Cisco models — not the Cisco SPA series, and not Bluetooth devices.
• Ciglow Headset — biggest strength: a slim, barely-there ear-hook design that connects wirelessly to two devices at once, with voice prompts and a rechargeable battery.
• Ciglow Headset — biggest trade-off: 5–6 hours of working time per charge and a 10-metre wireless range, so it is not built for nonstop desk shifts.
• Who each pick is for: MKJ for office and call-center staff on Cisco phones; Ciglow for mobile users who want a light wireless earpiece for calls and media.
The MKJ Cisco Headset is a corded, over-the-head headset with a single earpiece and an RJ9 jack. That last detail is the whole point of this product. RJ9 is the small modular connector used on many Cisco desk phones, and MKJ lists compatibility with a long run of them: 6921, 6941, 6945, 6961, 7821, 7841, 7861, 7931G, 7940/7940G, 7941/7941G, 7942G, 7945/7945G, 7960/7960G, 7961/7961G, 7962G, 7965G, 7970/7970G, 7971G, 7975G, 7985G, 8811, 8841, 8845, 8851, 8861, 8865, 8900, 8941, 8945, 8961, 9951 and 9971. If your desk phone is on that list, this headset is designed to plug in and work.
What it does best is live on your head for hours. The build uses PU materials and plastic parts with a reinforced cord, and MKJ states it is made to handle the wear that comes from office chair wheels and sharp edges — the everyday accidents that kill cheaper cords. The ear cushions are soft, the headband and microphone boom arm are adjustable, and the lightweight over-ear design is aimed at eight-hour wearing sessions. The mic uses noise control and sound isolation, which is what you want when you are taking calls in a room full of other people talking.
Ciglow Headset: Who It's For
The Ciglow Headset is a different animal entirely. It is a Bluetooth ear-hook headset — you suspend it over one ear rather than clamping it over your head — and it can be worn on either side. At 0.04 kg it is extremely light, and the ABS shell keeps it that way. The idea is that you forget you are wearing it.
Its standout feature is dual connection: it can pair with two phones or mobile devices at the same time, so you can take a call on one while staying linked to the other. That is genuinely useful if you carry a work phone and a personal phone, or a phone and a tablet. Ciglow also builds in voice prompts, so the headset tells you what is happening instead of leaving you guessing, and the chipset is rated for a stable connection within 10 metres.
On audio, Ciglow describes a speaker positioned close to the ear canal plus noise-reduction processing that targets the mid-to-high frequencies of the human voice — the practical effect being clearer speech and less background interference. The spec sheet lists a 42 dB sensitivity, a 90 mAh lithium battery, 5–6 hours of working time, 1–2 hours of charging and 160 hours of standby. The wireless spec is listed inconsistently across the sheet (Bluetooth 4.2 in the model name and style field, Bluetooth 5.2 in the description), so I would treat the exact version as unclear and judge it on what it does: stream audio, take calls, connect to two devices.
Who should buy it: people who want a wireless earpiece for phone calls and casual listening, delivery and field workers, drivers who want one ear free, and anyone who dislikes bulky headsets. Who should skip it: anyone who needs a full workday of continuous talk time, anyone who needs a wired connection to a desk phone, and anyone who wants a headband-style fit rather than an ear hook.
• Best for Cisco desk phones → MKJ Cisco Headset. It is built around the RJ9 jack and the long compatibility list above.
• Best for wearing all day at a desk → MKJ Cisco Headset. Soft cushions, adjustable headband and boom arm, over-ear fit.
• Best for wireless freedom → Ciglow Headset. Bluetooth, 10-metre range, no cable to your phone.
• Best for connecting two devices at once → Ciglow Headset. Its one-to-two pairing is a feature MKJ simply does not have.
• Best for long battery-free sessions → MKJ Cisco Headset. It draws power from the phone connection, so there is no battery to run down mid-shift; Ciglow is rated 5–6 hours per charge.
• Best for portability → Ciglow Headset. At 0.04 kg with an ear-hook design, it disappears into a pocket.
• Best for noisy open offices → MKJ Cisco Headset. Noise control plus sound isolation plus a boom mic positioned at your mouth is the more reliable setup for constant call handling.
• Best for mixed personal and work mobile use → Ciglow Headset. Dual pairing and voice prompts suit a phone-first workflow.
One caveat worth stating plainly: neither of these is a universal headset. MKJ only fits the Cisco models it lists, and it will not work on the Cisco SPA series. Ciglow only works wirelessly, so it cannot replace a corded desk-phone headset. Pick based on the socket you actually have, not on which one sounds better on paper.
If I were outfitting a desk with a Cisco phone and taking calls all day, I would buy the MKJ Cisco Headset. The RJ9 connection, the reinforced cord, the adjustable over-ear fit and the noise-cancelling boom mic are all pointed at exactly that job, and there is no battery to fail halfway through a shift. I would only choose the Ciglow Headset if my calls happen on a mobile phone and I want something weightless in my ear with dual-device pairing. In my opinion, MKJ wins for office and call-center work; Ciglow wins for wireless mobility. Check the current price on Amazon before you decide, since both sit in very different budget brackets.
FAQ
No. It is a Bluetooth headset, so it pairs with phones, tablets and other Bluetooth devices within about 10 metres. It has no RJ9 connector for a Cisco desk phone.
The listed figures are 5–6 hours of working time, 1–2 hours to charge and up to 160 hours of standby. That suits calls and listening sessions, not a full continuous workday.
Both use noise-reduction technology. For a loud office with nonstop calls, I would lean toward the MKJ Cisco Headset because its boom microphone and sound isolation are designed around desk-phone use, while Ciglow focuses on voice clarity for a single ear-hook wearer.
