Connector and signal-path guide
The four contacts from one CTIA combo socket are wired in parallel to two female sockets. Both listeners receive the same programme; there is no independent volume, mixing or electrical isolation.
Why this matters: 3.5mm plugs can look alike while carrying different numbers of contacts. TRS normally provides stereo left/right/ground; TRRS adds a microphone/control contact. Digital USB-C or Lightning audio needs conversion electronics rather than passive rewiring.
Direction check: one 3.5mm four-pole TRRS male to two 3.5mm four-pole TRRS female sockets. Do not buy by connector diameter alone.
Use scenarios
Shared listening. Feed the same stereo programme to two compatible headphones from one CTIA combo socket.
Headset plus microphone setup. Use selected TRRS combinations cautiously and keep only one microphone/remote active to avoid conflicts.
Home and office. Use one 3.5mm four-pole TRRS male to two 3.5mm four-pole TRRS female sockets where the connector direction matches the equipment.
Travel kit. The compact form is easy to keep with the device whose port standard it matches; label it SKU 30619 to avoid mixing similar adapters.
Setup and usability guidance
Comfort rule: start playback at a low volume. A new adapter can expose a different device volume setting than the one used previously.
- Step 1: Switch off or lower the volume on connected audio equipment before insertion.
- Step 2: Identify input and output direction from the connector types and labels; do not force a plug into a mismatched socket.
- Step 3: Insert every plug fully. A partially seated 3.5mm plug can lose one channel, swap contact behaviour or create noise.
- Step 4: Route the cable with gentle curves and keep strain away from device sockets.
- Step 5: Test audio at a low level, then test microphone and inline buttons only if this model supports them.
- Step 6: When disconnecting, grip the plug housing rather than pulling the cable.
Compatible devices and systems
Compatibility class: phones, tablets, laptops, controllers and other devices with one CTIA-style 3.5mm combo headset socket; TRS headphones and compatible CTIA TRRS headsets.
Connector first. Confirm the male/female connector, TRS/TRRS contact count and input/output direction. Brand name alone does not prove fit.
Host capability. For USB-C, Lightning or Bluetooth products, the host must support the relevant audio function. For passive cables, both endpoints must already provide analogue audio.
Headset standard. CTIA and OMTP four-pole wiring are not interchangeable in every product. Inline button behaviour can also differ by phone, headset and operating system.
Cases and recessed sockets. A protective case, recessed jack or closely spaced panel can prevent full seating even when the nominal connector matches.
What this product does
- Provides the one 3.5mm four-pole TRRS male to two 3.5mm four-pole TRRS female sockets connection described for SKU 30619.
- Splits one compatible combined 3.5mm CTIA headset socket into two parallel four-pole female sockets for shared listening or selected headset combinations.
- Uses the build: 20cm AV141 splitter with black TPE cable, gray metal/ABS housings, enamelled copper conductors, gold-plated contacts and an adjustable cable slider.
- Keeps buying guidance tied to this SKU rather than borrowing capabilities from a related cable family.
What this product does not do
- not a PC breakout into separate headphone and microphone plugs; not for two independent audio programmes; use only one headset microphone at a time because two microphones or remotes can interact.
- It does not guarantee louder sound, remove source noise or repair worn sockets, damaged cables or incompatible wiring.
- It does not create independent audio channels, mixing, electrical isolation or professional balanced conversion unless explicitly stated—which this product is not.
- It is not a power cable, charger, video adapter or networking accessory.
- It does not prove compatibility merely because another device has a visually similar port.
What to do
Match this SKU. Use 30619 only when one 3.5mm four-pole TRRS male to two 3.5mm four-pole TRRS female sockets matches the required direction.
Seat connectors fully. Push straight into clean sockets while equipment volume is low. A half-seated plug is a common cause of missing channels or microphone failure.
Test each function. Check stereo left/right, microphone, calls and controls separately; not every contact or button applies to every product.
Protect device ports. Leave slack, avoid side load and disconnect by the housing so the small audio socket is not used as a lever.
What not to do
Do not force a plug. Stop if the connector does not align or seat. Check case clearance, debris, plug diameter and male/female direction.
Do not assume TRS equals TRRS. Count the contacts and confirm stereo-only versus headset microphone/control requirements before connecting.
Do not pull the cable. Grip the connector housing. Pulling, twisting or sharply folding the cable can damage conductors and device sockets.
Do not connect live at high volume. Lower or mute amplification before changing analogue connections to avoid pops, feedback or unexpectedly loud sound.
Warnings and limitations
Hearing safety: begin at low volume and limit exposure. An adapter does not provide hearing protection.
Compatibility: not a PC breakout into separate headphone and microphone plugs; not for two independent audio programmes; use only one headset microphone at a time because two microphones or remotes can interact.
Environment: keep connectors dry, clean and away from extreme heat. Do not use a damaged or corroded plug.
Vehicles: pair, route and adjust controls while parked. Hands-free hardware does not remove the need to follow local driving and phone-use laws.
Selection guidance
1. Identify the job. Splits one compatible combined 3.5mm CTIA headset socket into two parallel four-pole female sockets for shared listening or selected headset combinations.
2. Check direction. one 3.5mm four-pole TRRS male to two 3.5mm four-pole TRRS female sockets.
3. Check contact standard. Decide whether the requirement is stereo TRS, CTIA headset TRRS, Bluetooth reception, USB Audio or Lightning audio.
4. Check limitations. not a PC breakout into separate headphone and microphone plugs; not for two independent audio programmes; use only one headset microphone at a time because two microphones or remotes can interact.
Troubleshooting
No audio. Confirm the source output, destination input and operating-system output selection. Reseat both ends with any obstructing case removed.
One channel only. Lower volume, cleanly reseat the plug and test with another known-good headphone/source. A partially inserted TRS/TRRS plug often drops a channel.
Microphone missing. Verify this SKU carries a microphone path, then check CTIA/OMTP wiring, input selection, app permissions and mute controls.
Buzz or crackle. Keep connections away from power noise, stop cable movement, clean dry plugs and test components one at a time to identify a worn socket or cable.
Controls behave oddly. Device and headset manufacturers can map inline buttons differently. Remove parallel splitters, confirm the standard and test basic audio before controls.
Level is too low. Check source and destination volume independently. Passive cables do not amplify; digital adapters still depend on host volume, DAC output and headphone load.
model check before ordering
Match SKU 30619, one 3.5mm four-pole TRRS male to two 3.5mm four-pole TRRS female sockets, 20cm and the stated compatibility boundary. Similar UGREEN audio cables can differ in TRS/TRRS contacts, direction, digital conversion, microphone support and colour.

Questions buyers ask.
What is UGREEN 30619 designed to do?
Splits one compatible combined 3.5mm CTIA headset socket into two parallel four-pole female sockets for shared listening or selected headset combinations.
Which connector direction does it use?
one 3.5mm four-pole TRRS male to two 3.5mm four-pole TRRS female sockets. Match both ends before purchase.
Does it need a driver or separate power?
No. It is a passive analogue cable or adapter.
Will microphone and inline controls work?
The contacts are paralleled, but two microphones or remotes can conflict; use one active microphone/control set at a time.
Can I use it with a phone case?
Only if the plug housing can seat fully. A deep or narrow case opening can block complete insertion; never force the connector.
Does it improve audio quality or volume?
It provides the documented connection. Real noise, level and fidelity depend on the source, destination, file, amplification, socket condition and environment; it is not a universal amplifier or sound enhancer.
Can it be used as a microphone adapter?
Only in the compatible headset arrangement described above. It is not a universal professional microphone interface.
What should I check if sound comes from one side?
Lower volume, push each plug fully into a clean socket, remove an obstructing case and test each source/headphone separately. A half-seated TRS/TRRS plug commonly loses a channel.
Is it suitable for studio, stage or balanced audio?
It is a consumer audio accessory, not presented as a balanced professional interface, isolated splitter or stage-rated installation cable.
Can I connect extra adapters or splitters?
Possibly, but each extra joint can add fit, wiring and signal-level uncertainty. Check TRS/TRRS standard and direction at every step, then test at low volume.
