Whether you need a 3.5mm stereo TRS plug for consumer electronics, a 6.35mm balanced TRS for studio monitors, or a 3-pin / 5-pin XLR connector for microphones and stage cabling, Verchil offers ready-stock SKUs, OEM/ODM customization, and full traceability from raw material to finished product.
Explore Our Audio Connector Categories
TRS Connector
Three-contact (Tip-Ring-Sleeve) connectors available in 3.5mm (1/8"), 6.35mm (1/4"), and right-angle 90° variants. Used for stereo audio, balanced mono signals, and headphone monitoring across consumer electronics, instrument cabling, and professional audio interfaces.
XLR Connector
3-pin, 4-pin, and 5-pin cylindrical connectors with locking latch and electromagnetic shielding. The industry standard for microphones, stage cabling, lighting DMX, and balanced line-level interconnection in live sound and broadcast.
What Is an Audio Connector?
Types of Audio Connectors — A Complete Comparison
Verchil specializes in TRS and XLR connectors. Need help comparing TRS, TS, TRRS, XLR, RCA and Speakon? Our Audio Connector Types guide covers each one in depth. To order, choose a product family below.
TRS connectors are the most versatile category, available in 2.5mm, 3.5mm, and 6.35mm sizes. For an in-depth breakdown of pinout, sizes, and wiring conventions, see our TRS Connector Sizes, Pinout & Wiring guide.
XLR connectors are the industry standard for balanced microphone signals and stage cabling. The 3-pin XLR is the most common, but 4-pin and 5-pin variants are used for DMX lighting control, intercoms, and stereo headphones. For wiring details and pin assignments, refer to our XLR Connector Pinout guide.
TS (Tip-Sleeve) connectors look identical to TRS at a glance but have only two contact points and carry unbalanced mono signals — the standard for electric guitars and patch cables.
TRRS adds a fourth pole to the 3.5mm jack to carry both stereo audio and a microphone signal, which is why it became the standard for smartphone headsets. The differences between TRS and TRRS are subtle but important — our TRS vs TRRS Connector comparison explains them in detail.
Why Source Audio Connectors from Verchil
18+ years of audio connector specialization — Our team has worked with mixing console brands, microphone OEMs, and stage equipment integrators since 2006, producing over 12 million audio connectors to date.
Vertically integrated manufacturing — In-house die-casting, machining, plating, and final assembly under one roof in Wenzhou. This means tighter quality control and shorter lead times.
Stringent QC at five checkpoints — Raw material inspection, in-process dimensional check, contact resistance testing, mating force test, and pre-shipment AOI inspection ensure consistent quality across every batch.
OEM/ODM ready — Custom housing colors, laser-engraved branding, custom pinouts, and pre-assembled cable harnesses available from MOQ 1,000 pcs.
Stable supply chain — Average lead time of 15 days for standard SKUs, 25–35 days for customized OEM orders.
Frequently Asked Questions
Can I use a TRS cable with an XLR equipment?
Yes, but only with a proper TRS-to-XLR adapter or wiring conversion. The pin assignments must match: TRS Tip → XLR pin 2 (hot), TRS Ring → XLR pin 3 (cold), TRS Sleeve → XLR pin 1 (ground). For full pinout details, see our XLR to TRS Connector guide.
What is the most durable audio connector for stage use?
XLR connectors with metal shells, locking latches, and strain relief are the most durable for live stage environments. Verchil's Neutrik-style 3-pin XLR series is rated for 10,000+ mating cycles and includes a chuck-type cable clamp.
Is 3.5mm TRS the same as 1/8 inch?
Yes — 3.5mm and 1/8" refer to the same connector size. Similarly, 6.35mm and 1/4" are identical, and 2.5mm is approximately 3/32". These dual naming conventions exist because the metric and imperial standards developed in parallel.
Do gold-plated audio connectors really sound better?
Gold plating does not improve sound quality directly — analog audio signals are not affected by plating material at audible frequencies. However, gold plating significantly reduces contact resistance drift over time by resisting oxidation, which means the connector maintains consistent performance over thousands of insertions. For studios, broadcast, and medical applications where reliability over years matters, gold plating is worth the cost.
What is the difference between male and female XLR connectors?
Male XLR connectors (with exposed pins) are outputs; female XLR connectors (with receptacles) are inputs. This convention is consistent across the entire audio industry and prevents accidental signal routing errors. For deeper detail, see XLR Male Connector guide and XLR Female Connector guide.
How do I choose between a 3-pin, 4-pin, and 5-pin XLR connector?
3-pin XLR is the standard for balanced mono audio (microphones, line-level). 4-pin XLR is used for headsets, intercoms, and stereo headphone amplifiers. 5-pin XLR is the standard for DMX lighting control and AES/EBU digital audio. The pin count is determined by the signal type, not by quality.
Can audio connectors carry phantom power?
Yes — XLR connectors are specifically designed to carry +48V phantom power for condenser microphones. The phantom voltage is applied to pins 2 and 3 simultaneously, with pin 1 as the ground return. TRS connectors typically do not carry phantom power in standard configurations.
What's the typical lead time for OEM audio connector orders?
Standard SKUs from Verchil ship in 15 days. Custom OEM orders with branded housings, special pinouts, or assembled cable harnesses typically take 25–35 days, depending on tooling and material availability.
Do you provide samples before bulk orders?
Yes. Verchil provides free samples (1–3 pieces per SKU) for qualified B2B buyers, with the customer responsible for express shipping. For customized samples requiring tooling adjustment, a one-time prototype fee applies and is credited against the first production order.
