• BQEYZ LIN CX31993 — biggest strength: a dedicated CX31993 DAC chip and 32-bit/384kHz support, so it feeds your existing 3.5mm earphones a cleaner signal than a bare adapter.
• BQEYZ LIN CX31993 — biggest trade-off: it is only an adapter. There are no earbuds, no microphone and no in-line controls in the box.
• ACANDYA USB C Headphone — biggest strength: everything in one package — wired USB-C earbuds, an HD microphone, an in-line button with volume control, and three sizes of silicone tips.
• ACANDYA USB C Headphone — biggest trade-off: it is a self-contained set, so you are locked into the bundled earbuds rather than your own.
• Who each is for: the BQEYZ for listeners who already own good wired earphones and want better sound from a USB-C device; the ACANDYA for anyone who needs calls, controls and a fit that works out of the box.
The BQEYZ LIN CX31993 is a small converter, and it is proud of it. One end is USB-C, the other is a 3.5mm female jack, and tucked inside is a CONEXANT CX31993 DAC chip running up to 32-bit/384kHz. In plain terms, that is a far higher sampling ceiling than a basic passive adapter can manage, and it means the digital-to-analog conversion is being handled by a component chosen for audio rather than whatever is cheapest.
The cable is the other half of the story. It uses monocrystalline copper plated with silver — the spec sheet lists 0.05mm × 14 strands × 7 bundles × 2 cores × 2 branches, a total of 392 wires — and BQEYZ describes the result as clear, delicate sound with a lively character. I read that as a deliberate attempt to keep the run short and clean rather than pad it with bulky shielding. The whole thing weighs about 8 grams with a roughly 6cm cable, so it disappears in a pocket, and it is finished in silver.
Who should skip it: if you need a microphone for calls, if you want a volume rocker on the cable, or if you do not already own a decent pair of 3.5mm earphones, this is the wrong purchase. You would be buying a bridge with nothing on the other side. It is also worth noting the connector is USB-C only — no Lightning, no USB-A.
ACANDYA USB C Headphone: Who It's For
The ACANDYA USB C Headphone is the opposite approach: a complete listening kit. You get wired in-ear buds with a USB-C plug, a built-in DAC chip for lossless transmission, and an HD microphone paired with an in-line push-button controller for answering and rejecting calls, skipping tracks and adjusting volume. If your phone has no 3.5mm jack — and most current ones do not — this replaces the whole chain in one purchase.
Fit gets real attention here. The buds are in-ear with an ergonomic shape and come with three sizes of ultra-soft silicone tips (S/M/L), which matters if you have small ears or you are buying for a child. The lightweight build is aimed at reducing fatigue over long sessions, and the housing mixes aluminium, plastic and rubber in a grey finish. A protective case and an earphone clip are included, and the 32-ohm impedance is a sensible figure for phone-driven listening.
Who should buy it: commuters and travellers who want one cable that handles music and calls, people who take a lot of voice calls and need to be heard clearly, and anyone who wants a fit that works without hunting for aftermarket tips. The compatibility list is long — recent iPhone, Galaxy S, Pixel, OnePlus, iPad and Motorola USB-C devices.
Who should skip it: if you already own a favourite pair of wired earphones, this set makes them redundant. And if sound isolation is your priority, note that ACANDYA describes sound isolation rather than active noise cancellation — it blocks some ambient noise through the seal, nothing more. It is also wired-only, with no wireless mode to fall back on.
• Best for improving earphones you already own → BQEYZ LIN CX31993. The CX31993 chip and 32-bit/384kHz support exist to serve hardware you already like.
• Best for taking calls → ACANDYA USB C Headphone. The built-in HD microphone and in-line button make calls the point, not an afterthought.
• Best for cable controls → ACANDYA. Answer, reject, skip and adjust volume without touching the phone.
• Best for portability → BQEYZ LIN CX31993. Around 8 grams and roughly 6cm of cable versus a full set of earbuds.
• Best for small or sensitive ears → ACANDYA. Three tip sizes (S/M/L) and a lightweight, low-fatigue design.
• Best for travel and commuting → ACANDYA. Wired USB-C earbuds plus a protective case are one item to pack.
• Best for a child or a second listener → ACANDYA. The small-tip sizing is explicitly aimed at children and women.
• Best for buyers who hate clutter → BQEYZ LIN CX31993, but only if you already own earphones worth keeping.
For most people reading this, I would buy the ACANDYA USB C Headphone. It solves the actual problem — no headphone jack — in one purchase, with a microphone, cable controls, three tip sizes and a case included. The BQEYZ LIN CX31993 is the better choice for a narrower, more specific buyer: someone who already loves their wired earphones and wants a cleaner signal rather than a new set. If that is you, the CX31993 chip and 32-bit/384kHz ceiling make it the more interesting piece of hardware. If it is not, the dongle leaves you without a microphone or controls. Decide which of those two people you are, and the choice is straightforward.
FAQ
Yes, per the compatibility list — recent iPhone models with a USB-C port are named, along with iPad, Galaxy, Pixel, OnePlus and Motorola devices. Check your exact model before buying, and remember it needs a USB-C port, not Lightning.
They solve noise differently. The ACANDYA relies on sound isolation from its in-ear seal plus three tip sizes to get that seal right. The BQEYZ does not isolate at all — it just passes audio through to whatever earphones you plug in, so isolation depends entirely on those.
The ACANDYA USB C Headphone. It has an HD microphone and an in-line button for calls. The BQEYZ LIN CX31993 has no microphone and no controls, so you would still need to handle calls on the phone itself.
Check the current price on Amazon before you commit, since both sit in very different product categories and the value math changes depending on whether you need a full set or just an adapter.
