If you want a compact USB-C-to-3.5mm adapter for wired headphones at work, choose BQEYZ LIN CX31993; if you need an amplifier that can feed several people’s headphones in a studio or rehearsal room, choose Bolanle PH400. These are not two versions of the same kind of headphone: one is a portable audio dongle, while the other is a multi-output headphone amplifier.
For everyday desk listening, the BQEYZ is the more relevant fit, provided your headphones have a 3.5mm plug and your device has USB-C. The Bolanle makes sense when the job involves multiple listeners, separate headphone connections, and a stationary setup. Neither product is itself a pair of ear clip headphones or open ear headphones.
• BQEYZ LIN CX31993 strength: a small USB-C-to-3.5mm adapter with a CX31993 DAC and support for audio up to 32-bit/384 kHz. Trade-off: it connects one set of wired headphones; it is not a multi-listener amplifier.
• Bolanle PH400 strength: eight 3.5mm and eight 6.35mm outputs, plus mono/stereo switching for shared monitoring. Trade-off: it needs a DC 12V/2A power supply and suits a fixed audio setup better than a portable work bag.
• Choose BQEYZ for a USB-C phone or other compatible device and one listener using wired headphones.
• Choose Bolanle for a studio, rehearsal, or recording setup where multiple people need headphone feeds.
BQEYZ LIN CX31993: Who It's For
The BQEYZ LIN CX31993 is a compact adapter, not a headphone. It connects a USB-C device to wired headphones with a 3.5mm connection. Its built-in CX31993 DAC supports audio up to 32-bit/384 kHz, and its cable is described as silver-plated monocrystalline copper. The unit is listed as about 8 grams, making its basic appeal easy to understand: carry a small connection accessory rather than a larger piece of audio equipment.
For work, I’d consider it for someone who listens alone from a compatible USB-C phone or device and already owns 3.5mm headphones. It may be a practical way to keep a wired listening setup in a laptop bag or desk drawer. The listed cable length is 6 cm, so it should be treated as a short adapter rather than an extension cable. Device compatibility is described broadly for USB-C and Android, but buyers should still check that their particular device supports audio through its USB-C port.
Skip it if you need several people to listen at once, need 6.35mm outputs, or are shopping for headphones rather than an adapter. It also does not provide a battery or wireless listening. For shoppers specifically seeking usb c charging ear clip headphones for work, this product is not that: it adapts a USB-C connection to a 3.5mm headphone jack and does not list ear clips or a charging case.
The Bolanle PH400 is described as an eight-channel headphone amplifier with 16 headphone outputs: eight 3.5mm and eight 6.35mm connections. It supports headphones up to 250Ω, and its mono/stereo switch lets the listener choose between those monitoring modes. A volume knob with a seven-color LED ring provides visible feedback, while the metal housing and DC 12V/2A input point toward a powered, stationary setup.
That makes it a more natural fit for shared listening in a studio, rehearsal space, or recording room than for one person’s portable work headphones. A group could connect compatible headphones through the available outputs, while the mono/stereo option addresses different monitoring needs. For a home recording setup or a work task involving several listeners, those connections are the defining advantage over the BQEYZ dongle.
Skip it if you want a lightweight adapter to carry with a phone, or if you only need a simple connection for one pair of headphones. It requires external power and does not claim noise cancellation or wireless operation. If your search is for open ear headphones for work, the PH400 is not a headphone either; it is an amplifier for connecting wired headphones.
• Best for connecting multiple listeners → Bolanle PH400. It provides 16 outputs across 3.5mm and 6.35mm jacks.
• Best for a small work bag → BQEYZ LIN CX31993. Its listed weight is 8 grams and its length is approximately 6 cm.
• Best for headphones rated up to 250Ω → Bolanle PH400. That headphone capacity is specified for the amplifier.
• Best for changing between mono and stereo monitoring → Bolanle PH400. It has a switch for those two modes.
• Best for a USB-C-to-3.5mm connection → BQEYZ LIN CX31993. The listed role is an adapter, not a stand-alone headphone amp for a group.
• Best for a powered studio or rehearsal station → Bolanle PH400. Its DC 12V/2A input and numerous outputs suit a setup that stays in one place.
• Best if you already own headphones and need an accessory, not another headphone set → either, depending on the job. Choose BQEYZ for a personal USB-C connection; choose Bolanle for a multi-listener arrangement.
How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
I would choose the BQEYZ LIN CX31993 for ordinary work listening if I had compatible USB-C gear and one pair of 3.5mm headphones. It is the more practical match for a compact, personal setup.
For a studio or rehearsal workspace, I would choose the Bolanle PH400 instead; its 16 outputs solve a different, group-focused problem. My work recommendation is the BQEYZ, but neither product replaces a dedicated pair of headphones.
No. The BQEYZ is a USB-C-to-3.5mm adapter with a DAC. The Bolanle is a powered headphone amplifier with multiple headphone outputs.
For one person listening from a compatible USB-C device, the BQEYZ is the closer fit. For work that involves several people monitoring audio together, the Bolanle’s 16 outputs and mono/stereo switch are more relevant.
The product information says it supports headphones up to 250Ω. It also has 3.5mm and 6.35mm outputs, so check that your headphones’ plug matches or can connect to the appropriate output.
Confirm that your device supports audio output through USB-C and that your wired headphones use a compatible 3.5mm connection. The listed adapter does not provide headphones, wireless playback, or a charging function.

The BQEYZ LIN CX31993 is a small adapter, not a pair of headphones. It connects a USB-C device to wired headphones with a 3.5mm connection. Its built-in CX31993 DAC supports audio up to 32-bit/384 kHz, and the cable is described as silver-plated monocrystalline copper. At a listed weight of 8 grams, it is intended to be easy to carry alongside a phone or other compatible device.
For work, I’d consider it if I listen alone and already own 3.5mm headphones. It could suit a desk setup or a work bag where I want to use wired headphones with a USB-C device. The listed adapter length is about 6 cm, so it is a short connector, not an extension cable. Compatibility is described broadly for USB-C and Android devices, but it’s sensible to confirm that your particular device supports audio output through its USB-C port.
Skip it if you need several people to listen at once, need 6.35mm headphone outputs, or are shopping for headphones rather than an adapter. It has no listed battery or wireless capability. And if your search is for usb c charging ear clip headphones for work, this is not that product: it adapts USB-C to a 3.5mm headphone connection and does not list ear clips or a charging case.
The Bolanle PH400 is described as an eight-channel headphone amplifier with 16 outputs: eight 3.5mm and eight 6.35mm.

Its volume knob has a seven-color LED ring, and the unit uses a DC 12V/2A power input with a metal housing.
Those features make it a natural fit for shared listening in a studio, rehearsal space, or recording room. Multiple people can connect headphones, and the available output types suit setups using either 3.5mm or 6.35mm plugs. For a work task that involves a group monitoring the same audio, its many outputs are the key distinction from the BQEYZ adapter.
