Audio Top-ups

Audio top-ups for your in-ears and headphones - portable USB DACs, headphone amps and Bluetooth adapters that add volume, clarity and drive from a phone, laptop or PC.

Buying guide

What a DAC does, and what an amplifier does

Two different jobs get sold in one small stick. A DAC, or digital-to-analogue converter, turns the digital file into an analogue waveform. An amplifier then raises that waveform to a level your earphone can actually use. Most USB-C dongles contain both, which is why one small device fixes a phone with no headphone socket and also makes a quiet pair play properly. If your source already sounds clean and loud enough, you do not need either.

When you genuinely need one

There are three honest reasons to buy. Your device has no 3.5mm jack, so you need a converter to use wired earphones at all. Your earphone is demanding - a planar or a low-sensitivity set - and sounds thin or requires near-maximum volume from a laptop. Or you want a microphone and volume controls on a USB-C connection that the phone does not provide. Outside those cases, an upgrade here is a refinement rather than a fix, and the money usually does more if you spend it on the earphone.

Reading the specifications that actually matter

Output power in milliwatts, quoted at a stated impedance, tells you whether a dongle can drive your set - and it is the only power figure worth comparing. The JCALLY JM7 uses a CX31993 chip rated at 28.2mW, which is ample for typical 16 to 32 ohm in-ears. The JM6 Pro pairs the same CX31993 with a MAX97220 amplifier stage, and the JM20 MAX steps up to a CS43131 with an SGM8262 stage and DSD256 support. Sample-rate numbers like 384kHz/32-bit are mostly headroom - almost nothing you listen to is mastered that high, so treat them as a spec-sheet line rather than a reason to buy.

Bluetooth adapters: cutting the cord on a wired set

A Bluetooth adapter clips onto a detachable IEM cable connector and turns any compatible wired pair into a wireless one, which is a much cheaper route to wireless than buying a true-wireless set. What decides quality here is the codec. The KZ AN01 supports LDAC, which carries far more data than the SBC and AAC baseline and is the reason to choose it for music. The TRN BT20 Pro runs Bluetooth 5.3 with AAC and SBC, and uses swappable connectors so it fits different IEM fittings.

Connectors, and the mistake to avoid

Check the fitting before you order. Most IEMs here use a 0.78mm 2-pin connector and some use MMCX, and an adapter built for one will not fit the other unless it ships with swappable ends. On the source side, a USB-C dongle needs a device that supports USB audio output - most modern Android phones and all current laptops do, while some older or budget phones do not. A plain 3.5mm converter with no DAC inside will not work at all on a phone that has no analogue output, which is the most common disappointment in this category.

Key terms, explained
DAC
Digital-to-analogue converter. It turns the digital audio file into the analogue signal an earphone can reproduce. Every phone and laptop already has one; an external DAC replaces it with a better implementation.
Headphone amplifier
The stage that raises the analogue signal to a usable level. It supplies the power, which is what a quiet or demanding earphone is short of - not more detail.
USB-C dongle DAC
A short cable containing both a DAC and an amplifier, powered by the phone or laptop it plugs into. The standard solution for a device with no headphone socket.
Output power
How much power the amplifier can deliver, in milliwatts at a stated impedance. The single most useful number for judging whether a dongle will drive your earphone properly.
Impedance matching
Pairing the source's output with the earphone's impedance. Very low-impedance, highly sensitive in-ears can hiss on a powerful desktop amplifier, while high-impedance headphones need more voltage than a phone provides.
Bluetooth adapter
A module that clips onto a detachable IEM cable and adds Bluetooth, converting a wired pair into a wireless one. Far cheaper than replacing the earphone with a true-wireless set.
LDAC
A high-bitrate Bluetooth codec that carries considerably more data than SBC or AAC. Worth seeking out if you listen to music wirelessly and your phone supports it.
SBC and AAC
The baseline Bluetooth codecs that every device supports. Perfectly serviceable for calls, podcasts and casual listening, and the fallback whenever a higher codec is unavailable.
0.78mm 2-pin and MMCX
The two common detachable IEM fittings - a flat two-pin plug and a rotating click-fit connector. A cable or adapter for one will not fit the other unless it has swappable ends.
Balanced output
A connection, usually 4.4mm, that gives each channel its own separate signal path rather than sharing a ground. It typically delivers more power and better channel separation than a 3.5mm single-ended output.
ENC microphone
A microphone built into the dongle with noise processing on the outgoing voice. It matters if you take calls on a laptop or a phone that has lost its headphone jack.
FAQ
Do I need a DAC for my IEM?

Usually not. Most in-ears here are low impedance and sensitive, so a phone or laptop drives them to satisfying volume unaided. Buy one if your device has no headphone jack, or if you own a demanding set - a planar, for instance - that sounds thin or needs almost full volume from your laptop.

What is the difference between a DAC and an amplifier?

The DAC converts the digital file into an analogue signal; the amplifier gives that signal enough power to move the driver. Most USB-C dongles contain both. If your earphone sounds clean but too quiet, you need amplification - not conversion.

Will a cheap USB-C to 3.5mm converter work on my phone?

Only if it contains a DAC. A passive adapter simply passes an analogue signal through, and a phone without a headphone jack has no analogue output to pass, so nothing plays. If your phone lost its jack, you need a converter with a DAC chip inside - which is what the dongles in this collection are.

Can I make my wired IEM wireless?

Yes. A Bluetooth adapter clips onto a detachable IEM cable and converts a compatible wired pair into a wireless one. Check the fitting first - most sets here are 0.78mm 2-pin and some are MMCX, and the TRN BT20 Pro ships with swappable connectors to cover both.

Does LDAC actually sound better than AAC?

It carries substantially more data, so it has more headroom for music where you would otherwise hear compression artefacts. Both ends must support it - the adapter and the phone. For calls and podcasts the difference is not worth chasing; for music on a capable set it is audible.

Does 384kHz/32-bit support matter?

Barely. Almost no music you can buy or stream is mastered anywhere near that, so the figure is headroom rather than a benefit. Judge a dongle on its output power, its noise floor and how it actually sounds, not on its maximum sample rate.

Will a more powerful DAC make my earphone sound more detailed?

Not by itself. Power fixes volume, control at higher levels, and bass that goes soft when the source runs out of headroom. It does not add detail that the earphone cannot resolve. If you are choosing between a better DAC and a better earphone, the earphone changes the sound far more.

Why do I hear a faint hiss with my in-ears?

Very sensitive in-ears reveal the noise floor of whatever is driving them, so a powerful source can hiss with an efficient set even when it is silent with headphones. Using a lower-gain setting or a dongle better matched to sensitive in-ears solves it.

What is a balanced 4.4mm output for?

It gives each channel an independent signal path instead of sharing a ground return, which usually means more available power and better channel separation. You need a cable terminated in 4.4mm to use it, and on efficient in-ears the practical gain is modest.

What warranty and delivery do I get?
