• MYPIN 192kHz — biggest strength: it's a digital-to-analog converter and headphone amplifier in one box, with Optical, Coaxial and 3.5mm inputs, Bluetooth 5.0 reception, and a physical volume knob that also acts as the on/off switch.
• MYPIN 192kHz — biggest trade-off: it is a stationary desktop unit that needs its own space and cabling, and it works as a Bluetooth receiver only — it will not transmit audio out to wireless headphones.
• ACANDYA USB C Earbuds — biggest strength: a complete wired listening setup in your pocket — USB-C plug, inline mic and remote with volume control, a DAC chip built into the connector, three ear-tip sizes and a storage case.
• ACANDYA USB C Earbuds — biggest trade-off: they only work with USB-C devices, the cable is fixed at 1.2m, and being in-ear buds they isolate sound passively rather than offering any active noise cancelling.
• Who each pick is for: MYPIN for someone building a home audio chain around a TV, amplifier or older wired headphones; ACANDYA for someone who just wants wired sound with volume control on a modern phone, tablet or laptop.
The MYPIN 192kHz is not really a pair of headphones — it's the box that sits between your headphones and your source. Feed it an Optical, Coaxial or digital audio signal, and it converts that to stereo analog output on RCA and 3.5mm jacks. There's a built-in high-performance DAC chip handling sampling rates from 32 up to 192kHz at 24-bit, and the headphone amp section is rated for headphones between 16 and 300Ω. That impedance window is the interesting part: it covers everything from sensitive in-ears up to fairly demanding full-size cans, which is more than most phone jacks will drive cleanly.
It also does Bluetooth 5.0 reception with a dedicated antenna, so a phone or tablet can stream to it wirelessly, and there's a built-in microphone path for phone calls, switched with a selector button. Note the direction: Bluetooth in, analog out. It is not a transmitter, so it won't send audio to Bluetooth headphones. In my opinion this is the right pick for a home theater, teaching setup, conference room or anyone with a TV or amplifier feeding wired headphones. Skip it if you want something pocketable, or if you're trying to add wireless output to a wired source.
ACANDYA USB C Earbuds: Who It's For
The ACANDYA USB C Earbuds are the opposite kind of product: a self-contained wired headset that plugs straight into a USB-C port. There's a DAC chip in the connector, dynamic drivers covering 20Hz to 20,000Hz at 32Ω impedance, and a 1.2m cable. The inline remote gives you a microphone plus button controls for volume and track switching, so you keep wired-headphone volume control without touching the phone.
Fit is clearly a priority here. The buds are in-ear with three ear-tip sizes in the box (medium pre-installed), and the design leans on sound isolation rather than active noise cancelling — the seal does the work. The housing is aluminum and TPE, in black, and it ships with a protective case plus the spare tips. For everyday listening, calls and gaming on a phone or tablet, that's a tidy package.
Compatibility is the deciding factor. The list covers iPhone 15/16/17 family, iPad 10th gen, iPad Air and Pro models, MacBook Pro, Samsung Galaxy S20 through S26 including the Ultra and FE variants, Tab S9 series, Z Flip and Z Fold models, Google Pixel 2 through 10, OnePlus, Motorola and other USB-C devices without a 3.5mm port. If your device has a headphone jack and you'd rather use it, these are the wrong buy. If your phone dropped the jack — which is most of them — they're a straightforward answer.
• Best for wired headphone volume control at a desk → MYPIN 192kHz. The knob controls the 3.5mm and RCA outputs together and doubles as the power switch.
• Best for volume control on the move → ACANDYA USB C Earbuds. The inline button remote handles volume and track skipping right on the cable.
• Best for TVs, amplifiers and home theater → MYPIN 192kHz. Optical, Coaxial and RCA connectivity plus a 16–300Ω headphone amp is built for that chain.
• Best for phones and tablets without a headphone jack → ACANDYA USB C Earbuds. USB-C plug, no adapter needed on the listed devices.
• Best for higher-resolution sources → MYPIN 192kHz. It handles 32–192kHz/24-bit conversion with 2.0ch PCM/LPCM formats.
• Best for calls → both can do it, differently. MYPIN routes Bluetooth calls through its built-in mic and selector button; ACANDYA has an inline mic on the cable.
• Best for portability → ACANDYA USB C Earbuds. 0.03kg, a 1.2m cable and a storage case versus a stationary copper-bodied unit measuring roughly 3.35" by 3.94".
• Best if you want to keep your own headphones → MYPIN 192kHz. It amplifies whatever you already own, from 16Ω up to 300Ω.
If I had to pick one, I'd pick based on what's already on my desk. For a TV, console, amplifier or a pair of wired headphones I already love, I'd buy the MYPIN 192kHz — the impedance range, the multiple inputs and that physical volume knob solve a real problem that software volume sliders don't. For a phone or tablet with no headphone jack and a need for something that just works out of the box, I'd buy the ACANDYA USB C Earbuds instead: mic, remote, three tip sizes and a case, all in one purchase. They're not competing for the same slot in your bag or on your shelf. Check the current price on Amazon before you commit, since that's the one thing specs can't tell you.
how to disable volume control on wired headphones
On most wired headphones, the inline remote's volume buttons are handled by the device, not the cable — so you can't truly disable them at the headphone end. With the ACANDYA USB C Earbuds, the inline remote is the volume control, so the practical option is to leave it alone and adjust volume on the phone itself. On the MYPIN 192kHz, you can simply leave the knob at a fixed position and control volume at the source, or use the knob as the on/off switch.
do earbuds have volume control
Do I need a DAC for USB-C earbuds?
Not necessarily. The ACANDYA USB C Earbuds already have a DAC chip built into the connector, which is what lets them output analog audio from a USB-C port. The MYPIN 192kHz is a separate DAC and headphone amp for sources like Optical, Coaxial, Bluetooth or 3.5mm, so it serves a different role — converting and amplifying a signal for headphones you supply yourself.
No. It's a Bluetooth receiver, not a transmitter — it accepts audio from a phone or tablet over Bluetooth 5.0 and outputs it as analog stereo through RCA and 3.5mm. To listen wirelessly you'd need Bluetooth headphones paired to your source directly, or a separate transmitter. The MYPIN's job is feeding wired headphones and amplifiers.
