Big on Comfort and Clarity

With more color, connector, and clip options than other headset mics in its class, the Shure TwinPlex TH53 offers the flexibility and clarity to power theaters, studios, conference halls, and houses of worship all over the world. The TH53’s extremely natural sound signature complements speakers and performers of all qualities, with low noise, dynamics, and dependability that far exceed its price. Its ultra-compact dual-diaphragm capsule boasts twice the surface area of other leading subminiature microphones. This increased size, paired with its omnidirectional polar pattern and superior off-axis consistency, lends the TH53 a natural speech pickup that excels in any live environment. What’s more, a lightweight and fully adjustable headset frame primes the mic element for optimal speech/vocal pickup without obscuring sight lights. So whether you’re filming or presenting, teaching or performing, the TH53 holds up to extreme scrutiny. A paintable, 1.6mm-diameter reinforced cable is also included.

Stress tested beyond real-world conditions

Lab-tested, road-ready Shure TwinPlex headset microphones keep ticking when all others fail. Every microphone and cable in this series is treated to a series of exhaustive stress tests to ensure dependability and premium sound in real-world performance applications.

  • Sweat Test — It’s no secret that performers sweat into their headworn mics. The hot lights, the performance pressure — it’s enough to make even the most seasoned professional a little warm under the collar. That’s why Shure’s TwinPlex mics have undergone rigorous moisture testing to resist sweat-related noise and mic failure in the heat of a performance. Shure’s custom-designed SweatBot saturates its TwinPlex test capsules in a 99% humidity soak for a full 24 hours. Mics are then rigorously tested to ensure noise-free, crystal-clear voice and speech pickup. The secret is a superhydrophobic coating, which is proven to keep perspiration out of the mic capsule.
  • Flex Test — Shure’s medical-grade TwinPlex spiral test cables have been stretched, bent, and smashed to their limit in the name of audio excellence. The breaking point has been shown to be one so extreme that most performers and engineers are likely never to reach it in their careers. Even after years of use and abuse, TwinPlex cables are engineered to deliver pro sound and performance without the memory effects, cracking, and stiffening common to lesser cables.

Dual-diaphragm design

Dual diaphragms in the Shure TH53 tailor this mic to all qualities of speakers and performers. From the huskiest baritone to the brightest soprano, the natural tone of every voice is brought to life through this marvel of modern engineering. Beyond its consistent on- and off-axis frequency response, the TwinPlex TH53 delivers a wide-open dynamic range with high SPL handling and a low noise floor to maintain the excitement and energy of every performance. The TH53 is also built to resist RF interference from bodypack wireless systems for a cleaner signal in any live environment.

Double-shielded 1.6mm cable

An included medical-grade cable with fiber reinforcement gives your TwinPlex headset mic the endurance to go the distance, night after night. This cable is built on Shure’s exclusive Spiral Cable technology to resist the kinking, cracking, and memory effects common to other mini mic cables. A redundant ground wire in the cable serves as secondary shielding for added strength and longevity. Even better, the TwinPlex cable is paintable to match any performer, environment, set dressing, and costume. If you’re after a mic that’s built to stand up to the rigors of the modern live performance environment, you’ll find it in the Shure TwinPlex TH53 from Sweetwater.

Shure's TwinPlex headset mics are available in multiple color and connector options.

  • A lightweight and flexible headset mic for any stage or set
  • The most comprehensive connector and color options within the TwinPlex series
  • Ruggedly built and exhaustively engineered
  • Stress tested to ensure long-term pro performance

What is Certified Open Box Gear?

At Sweetwater, we're so picky that what we call "Certified Open Box" is actually better than what most music retailers sell as "new" gear! Our gear hasn't endured hundreds of people a week plunking away at all the keyboards, fumbling through Stairway to Heaven on every guitar or playing with every fader and knob on a mixer or control surface.

Certified Open Box (also known as a demo) means we’ve had it out of the box for our YouTube channel, displayed at events, tested in our studio, or maybe it was in a customer’s hands for a few days and isn’t ‘factory fresh’ as a result. Every Certified Open Box item we sell has Sweetwater’s 2-year Total Confidence Coverage™ warranty and has been tested and verified up to ‘new’ specs by our factory-authorized technicians to make sure it’s in perfect working order before we ship it to you.

When you buy a Certified Open Box item at Sweetwater, you get:
  • 2-year Total Confidence Coverage Warranty™!
  • Products inspected and tested by our factory-authorized techs, guaranteed to function like new (or better)!
  • FREE shipping on most items
  • Equipment that will MEET or EXCEED your expectations!

Reviews

Not for small ears
I found it bulky and not very stable, especially when you are sweating. the mic keeps turning. Not for people with small ears. For this price, I should have saved up and get one of the DPA.
