If you want detailed, bass-forward wired listening for audiophiles, choose BASN Metalen 4; if you need a rechargeable wireless monitor for rehearsals or live performance, choose Befuoiu UHF. The BASN is the more direct fit for personal music listening; the Befuoiu is built around moving freely while monitoring audio.
BASN Metalen 4 vs Befuoiu UHF at a Glance
• BASN Metalen 4’s strength: Four hybrid drivers per earbud, two cable options, and included ear tips and memory foam. Trade-off: It is wired, so you are connected to your playback device.
• Befuoiu UHF’s strength: Wireless monitoring with 16 adjustable channels and a rechargeable transmitter and bodypack receiver. Trade-off: Its stated battery life is five hours, and you need to manage charging.
• BASN fits: Listeners, musicians, and bass players who want wired in-ear monitors and a choice of cables.
• Befuoiu fits: Singers, DJs, bands, and studio or live performers who need a wireless monitoring setup.
• Quick distinction: The BASN is an earphone choice; the Befuoiu is a wireless IEM system.
The BASN Metalen 4 pairs two balanced armature drivers with two dynamic drivers in each earbud. Its stated frequency range is 16 Hz to 25,000 Hz, and the design emphasizes pronounced bass, warm mids, and detail. That combination makes it a plausible fit for someone who wants wired in-ear listening with a bass-forward character, rather than a neutral-sounding setup on paper.
It comes with two 4.9-foot cables: a silver-plated cable without a microphone and a fiber cable with an inline microphone. Both use detachable MMCX connections, so the cable can be removed rather than being permanently attached. The included kit also has silicone tips in small, medium, and large sizes, memory foam tips, a carrying case, a cleaning brush, a T-shirt clip, hook-and-loop cable strips, and a quarter-inch adapter.

I’d consider the BASN if I wanted a wired monitor for listening, practice, or a setup where a cable is not a problem. The microphone cable adds a speaking option, while the other cable keeps the listening setup simpler. I’d skip it if freedom from a cable is essential: this is a wired, 3.5 mm-jack earphone, not a wireless system.
Befuoiu UHF: Who It's For
The Befuoiu UHF is a wireless in-ear monitoring system, not simply a pair of wireless earbuds. It includes a transmitter and a bodypack receiver, connects over UHF, and offers 16 adjustable channels. The stated purpose is monitoring in contexts such as band rehearsal, studio work, DJ use, and live performance.
That makes it the more relevant option when a cable between the performer and audio source would get in the way. The trade-off is practical: you must charge it, and five hours is the stated operating time. The product information does not give a driver configuration, frequency range, or detailed sound signature, so I would not choose it over the BASN on claims about bass, tonal balance, or fine listening detail.
• Best for wired music listening → BASN Metalen 4. Its four-driver hybrid design and stated emphasis on bass, mids, and detail give a clearer picture of its listening character.
• Best for moving around during a performance → Befuoiu UHF. The transmitter and bodypack receiver provide a wireless monitoring arrangement.
• Best for a choice of cables → BASN Metalen 4. It includes a cable with an inline microphone and a separate silver-plated cable without one.
• Best for changing channels to address frequency overlap → Befuoiu UHF. It has 16 adjustable channels, with manual channel changes intended for situations where another device is using the same frequency.
• Best for a rechargeable performance kit → Befuoiu UHF. Its transmitter and receiver are rechargeable, with a stated two-hour charge time and five-hour use time.
• Best for included ear-tip options → BASN Metalen 4. It comes with three sizes of silicone tips plus memory foam tips.
• Best for a defined, bass-forward sound profile → BASN Metalen 4. The product details specifically describe strong bass and warm mids; the Befuoiu’s supplied specifications do not describe its tonal balance.
• Best for a wireless system in a band or rehearsal setup → Befuoiu UHF. Its intended use and included XLR-to-6.35 mm adapter point toward connecting the system to performance equipment.
A search for the best spatial audio headband headphones for audiophiles points toward a different kind of product. Neither of these is a headband headphone, and the specifications here do not establish spatial-audio processing. Likewise, shoppers looking for the best noise cancelling open ear earbuds for audiophiles should note that neither product is described as open-ear. The BASN lists sound isolation, while the Befuoiu lists adaptive noise cancellation; those labels do not make either one an open-ear earbud.
My Verdict
I would choose the BASN Metalen 4 for audiophiles who want wired listening, a described bass-forward sound, and two detachable cable options.
It gives more specific information about its drivers and sound profile than the Befuoiu does.
I’d choose the Befuoiu instead when the priority is wireless monitoring for rehearsal or performance, not a documented listening signature.
My pick is the BASN for personal listening; the Befuoiu is the more purpose-built choice for performers who need UHF freedom.
No. It is a wired in-ear monitor with a 3.5 mm jack and two included detachable MMCX cables. Choose the Befuoiu if you need a UHF wireless transmitter-and-receiver setup.
The listed battery life is five hours, with a stated charge time of two hours. That makes charging part of planning for longer rehearsals or performance sessions.
The BASN is the clearer match based on the supplied specifications: its four-driver hybrid arrangement is described as delivering enhanced bass, warm mids, and detail. The Befuoiu’s listed information does not specify its driver setup or sound signature.
Neither product’s supplied details state an IPX7 rating. BASN is described as sweatproof, but that is not the same as a stated IPX7 certification; the Befuoiu specifications do not provide an IPX7 claim either.
