• MYPIN 192kHz — biggest strength: it is a full digital-to-analog converter with a Bluetooth 5.0 receiver, a 192K/24bit DAC chip and a headphone amplifier rated for 16–300Ω cans, all fed through one volume knob.
• MYPIN 192kHz — biggest trade-off: it is a stationary desktop device that needs its own power and a set of cables; it is not something you wear, and it is a Bluetooth receiver only, never a transmitter.
• Bulktech 10 — biggest strength: ten complete wired on-ear headphones in one box, each with a 5-foot cable, a 3.5mm jack and a remote control for volume — ready to hand out.
• Bulktech 10 — biggest trade-off: sound quality is basic by design, there is no microphone, no noise control, and the impedance is a fixed 32Ω that you cannot tune.
• Who each pick is for: MYPIN 192kHz suits one person building a home theater, desk or training-room audio chain. Bulktech 10 suits anyone equipping many people at once — schools, libraries, computer labs, museums, coaches, parents.
Think of the MYPIN 192kHz as the hub at the center of a wired audio setup. It takes digital signals in — optical, coaxial, or Bluetooth 5.0 from a phone or tablet — and puts analog stereo out through RCA and 3.5mm jacks. Inside sits a high-performance DAC chip running up to 32–192K/24bit, so the conversion stage is doing real work rather than just passing a signal through. If your TV, console or older receiver only offers an optical or coaxial output and your speakers or headphones only take analog, this is the box that bridges the two.
The headphone side is where the volume control earns its place. The 3.5mm output doubles as a headphone amplifier rated for 16–300Ω, which covers everything from sensitive in-ears up to harder-to-drive over-ears. One knob adjusts the headphone jack and the RCA output together, and that same knob is also the on/off switch — a small detail, but it means you can shut the unit down without crawling behind your desk to pull the plug. There is a built-in microphone and phone-call support over Bluetooth, and the selector button handles call control, so it can double as a speakerphone path in a small conference or training room.
Buy it if you want one tidy device that consolidates DAC, Bluetooth receiver, headphone amp and volume control, and you are happy for it to live on a shelf. Skip it if you need headphones to wear while walking around, if you want to send Bluetooth audio out to a speaker (this is a receiver, not a transmitter), or if you need many units for many people. The copper-bodied enclosure measures roughly 3.35" by 3.94", so it is a compact desktop footprint rather than a pocket device.
The Bulktech 10 is a different animal entirely: a ten-pack of wired on-ear headphones with leather-look ear cushions, a 3.5mm jack and an inline remote for volume. Every unit is wired, with a 5-foot cord, and the cups swivel so they stack and store flat — which matters far more than it sounds when you are packing thirty of these into a cupboard. The build is deliberately light and adjustable, sized to fit both adults and children, and the cord is a thick one, chosen for the kind of daily handling kids put headphones through.
The remote control on the cable handles volume, and that is the whole control story: no microphone, no noise cancelling, no app. Impedance is 32Ω across the board, driven by a dynamic driver, so they will play from essentially any phone, tablet, PC or Chromebook without a separate amp. The frequency range is listed as 20–100, which tells you these are voiced for speech intelligibility and everyday listening rather than critical music work.
Buy them if you need quantity, uniformity and a simple volume control at arm's reach: classrooms, remote learning, libraries, art galleries, museums, health centers, kindergartens, computer labs, airline loaners or a family with several children. Skip them if you are shopping for one pair of serious headphones for yourself, if you need to make calls, or if you want isolation from surrounding noise — noise control is listed as none, which is exactly what you would expect from an open on-ear design at this level.
• Best for turning digital audio into analog → MYPIN 192kHz. Optical, coaxial and Bluetooth in; RCA and 3.5mm out.
• Best for driving a range of headphones → MYPIN 192kHz, thanks to the 16–300Ω headphone amplifier stage.
• Best for one volume knob that rules everything → MYPIN 192kHz. It adjusts the headphone jack and RCA output together.
• Best for equipping a group on a budget → Bulktech 10. Ten complete wired headphones in one purchase.
• Best for kids and shared environments → Bulktech 10. Lightweight, adjustable, swivel cups, thick cord, 32Ω so any device drives them.
• Best for hands-on volume at the cable → Bulktech 10. The inline remote puts volume next to your hand, which is often easier than reaching for a source device.
• Best for calls → MYPIN 192kHz. It has a built-in microphone and Bluetooth call support; the Bulktech set has no mic.
• Best for portable, on-the-go listening → Bulktech 10. The MYPIN unit is a powered desktop converter, not a wearable.
If I were buying for myself, I would take the MYPIN 192kHz. In my opinion it is the more capable piece of hardware: it solves a real problem (getting digital audio out to analog gear) and it adds a genuine headphone amplifier with a volume control that works across both outputs, plus Bluetooth and call handling. The Bulktech 10 is the smarter buy only when the job is outfitting many listeners at once, where ten wired headsets with inline volume remotes and stackable cups simply get the job done. Different problems, different answers — but for a single listener building a setup, MYPIN is my pick.
how to disable volume control on wired headphones
On most wired headphones the inline remote is a passive resistor-based control, so there is no software switch to turn it off. The practical workaround is to set the remote to maximum and adjust volume from the source device instead. With the Bulktech 10, that means leaving the cable remote at full and using your phone, tablet or PC slider.
do earbuds have volume control
Some do, some don't — it depends on the model, not the category. On-ear and over-ear wired headphones such as the Bulktech 10 include an inline remote control for volume, and the MYPIN 192kHz has its own volume knob on the unit itself. Neither design guarantees volume control on every device, so check the spec before buying.
No. It is a Bluetooth receiver, so it accepts audio from a phone or tablet and outputs analog sound. It cannot send audio out to a Bluetooth speaker or pair of Bluetooth headphones.
Yes. The 3.5mm jack is universally compatible, so you can plug them straight into a phone, tablet, PC or Chromebook and control volume from the device. The inline remote is there for convenience, not as a requirement.
