Description
The Cuzabe CBH11 is a neckband headset with earplug shaped tips, sold explicitly for industrial safety. The product name says hearing protection use, the bullets say hearing protection, and one of them recommends it for a shooting range. What the listing does not contain, anywhere, is a noise reduction rating. No decibel figure, no test standard, no laboratory. That absence is the most important fact about this product and it governs everything below.
What it claims to be
Cuzabe describes a flexible neckband with braided wires running to in ear tips described as tri layer silicone, a built in microphone and a multifunction button. The pitch is that you can wear hearing protection and listen to music at the same time on a work site, with the wires hidden under a shirt. Twenty hours of battery and a protective pouch complete the package. There is no charging case, so the quoted battery figure is the whole story rather than a combined total.
The appeal is real. Wearing earbuds under muffs is awkward, and a single product that does both is an obvious idea. But a product sold on attenuation has to publish the attenuation, and this one does not.
The hearing protection claim, examined
The bullets say the tips significantly reduce harmful noise, block out ambient noise so you can play music all day in safety, and provide what the copy calls the ultimate in hearing protection. The recommended settings include landscaping, welding, woodworking, farming, yard work and a shooting range.
None of that is backed by a number. In the United States, hearing protectors carry a noise reduction rating derived from testing under a defined standard, and that rating is what lets you calculate whether a given protector is adequate for a given exposure. There is no such figure on this listing. Without it there is no way to know whether these attenuate 10 decibels or 30, and no basis on which to compare them to a certified protector.
The shooting range recommendation deserves a direct objection. Firearm noise is impulse noise at levels that can cause permanent damage from a single unprotected exposure, and it requires protection with a known, adequate rating. An earplug shaped Bluetooth headset with no published rating is not that. This review makes no claim that the CBH11 protects your hearing at any level, and it should not be relied on for occupational exposure. If you work somewhere loud enough to need protection, take the protector from your employer’s hearing conservation program.
There is a second problem the copy never addresses. Playing music inside a sealed earplug at high volume substitutes one noise exposure for another. A protector that lets you listen loudly all shift is not protecting you from the thing coming out of the drivers.
Connection, and a specification that contradicts the bullets
Bluetooth is given as 5.0 with a range of 33 feet, and the structured field records the same figure as 1E+1 meters, which is scientific notation for 10 meters. Those agree with each other, which is a rarity in this catalog. Pairing is described as pressing a single multifunction button.
The noise control field on the specification reads active noise cancellation. Nothing in the bullets describes active cancellation. There are no cancellation microphones mentioned, no cancellation modes, no toggle and no decibel figure. Everything the copy describes is passive: silicone tips sealing the ear canal. Those are two incompatible accounts of how this product reduces noise, and the passive one is the only one with any supporting detail. Treat the specification field as an error.
No codec is named anywhere. Not SBC, not AAC, not aptX, not LDAC. SBC is the only safe assumption. The fourth bullet claims delicate sound and solid bass from high quality copper wire and a Japanese sound diaphragm, neither of which is a specification you can check. The frequency range field gives the standard 20 Hz to 20,000 Hz that appears on almost every listing.
Battery: 20 hours, stated once and consistently
Cuzabe quotes 20 hours of playback, and the structured battery life field agrees at 20 hours. Charging takes two hours. Because there is no charging case, the 20 hours is the total, which removes the usual ambiguity between bud runtime and combined figure entirely. On a product intended for full working days that is a sensible design decision and a clean disclosure.
As always, 20 hours is a best case measurement at moderate volume, and heavy call use will not match a music playback figure.
Fit, and the water wording
The tips are described as tri layer silicone and ergonomically shaped for a tight fit. How many sizes ship in the box is never stated. On any sealing earbud that is an omission; on a product whose entire value rests on attenuation it is the single largest gap on the page, because a tip that does not seal in your ear canal does not attenuate. Ask the seller how many sizes are included before ordering.
The product name says waterproof. The fifth bullet describes the product as water and sweat resistant, able to withstand wetness, spills, sweat and light rain. That is splash level language, which corresponds to a code around IPX4. The structured specification records waterproof with no code at all. There is no IP rating published anywhere on this listing, so this review will not call the CBH11 waterproof. Treat the protection as unstated, note that no consumer IP code covers seawater or pressurized water, and remember that seals degrade with age and sweat exposure.
What the numbers say, and what else to consider
Cuzabe records the sales position as ranked 1,358th in Electronics and 211th in earbud and in ear headphones, but the star average is 3.6 across 583 ratings. That is the lowest customer rating of anything in this part of the catalog by a clear margin, and on a product first listed in November 2022 it is a signal worth weighing rather than dismissing. The included components field lists only a protective case. Item weight is 0.06 kilograms, or 2.08 ounces, which agree with each other and are plausible for a neckband.
Multipoint is not mentioned. There is no app, no EQ and no firmware update path described. For alternatives in the same shape, the MIPEACE LMI04 at least publishes a noise reduction figure, though it names no test standard for it either. The LG TONE Flex is the mainstream call focused neckband, and the Boean U8 and Boean U18 take the sport route instead. All appear in our earbud headphones section and the wireless headphones listings.
Who should buy it, and who should not
Buy the CBH11 if you want a cheap neckband with sealing tips and 20 hours from one charge, for a moderately noisy environment where hearing protection is a preference rather than a requirement. Do not buy it as workplace hearing protection, because no noise reduction rating is published. Do not use it on a shooting range. And be aware that its customer rating is the lowest in this group.
