A Vocal Mic with Astonishing Accuracy!

You will be astonished when you first use an Earthworks microphone! You will hear more clarity, detail and transparency than you have ever heard from a microphone. Musical instruments and vocalists will sound more real, vibrant and alive. The Earthworks SR20 is one of the most accurate mics we've ever heard.

Earthworks SR20 Condenser Microphone at a Glance:
  • Delivers the sonic equivalent of hearing live music
  • Captures attack and punch of percussive sounds
  • No "smearing" of low-level signals
  • Uniform response across all frequencies
  • Amazing extended frequency response

Delivers the sonic equivalent of hearing live music
Most sound recordings don't live up to the sonic experience of listening to live music. Earthworks has discovered that audio equipment with extended high frequency response and better time domain performance will yield a substantial audible improvement and more life-like results. People continue to be astonished and amazed when they use the SR20 with its extended high frequency response. While you may not be able to hear pure tones beyond 15kHz, you will hear the difference in the time domain and impulse response of live music.

Captures attack and punch of percussive sounds
The Earthworks SR20 offers superior impulse response - the speed and accuracy with which a microphone responds to a signal with fast rise times, such as percussion, guitar and brass. This helps retain the attack, punch and excitement in recorded music and sounds.

No "smearing" of low-level signals
The SR20 also features fast diaphragm settling time - how long it takes a diaphragm to return to rest. If a microphone's diaphragm is still vibrating from previous sounds while it is trying to pick up new sounds, it adds coloration and smearing of low-level signals that contain important minute details. The SR20 delivers accurate reproduction of ant sound source!

Uniform response across all frequencies
The Earthworks SR20's pickup pattern technology maintains accuracy and uniform frequency response throughout the pickup pattern. With this improved uniformity there is no spotlighting, less off-axis phase problems, and more gain before feedback.

Extended frequency response
The SR20 has an extended frequency response, capturing high-frequency details and overtones. This is a clear advantage when using today's higher sampling rates for recording. Earthworks' proprietary technology provides higher frequency response, better impulse response and time domain accuracy, which will capture overtones and details that conventional microphones mask.

Earthworks SR20 Condenser Microphone Features:
  • Spectacular vocal microphone
  • Small-diaphragm condenser with cardioid pattern
  • Frequency response 50Hz-20kHz
  • Accurately captures a voice with the same precision and quality up to 90 degrees off-axis
  • Warm, not boomy, when used up close
  • Unique windscreen assembly eliminates the popping of Ps
  • More gain before feedback than other microphones
  • Also outstanding for piano, guitar, drums, brass, woodwinds and other instruments
  • Handles up to 145dB SPL
  • Requires +48V phantom power
For sonic accuracy you can't beat the Earthworks SR20!

Awesome mic

Not kidding about the near perfect cardioid pattern. It really is. Fantastic sound from this mic. I picked up one second hand at a great price. Yikes! It has ruined me. All other sub $500 cards are shown up so badly I need more of the SR20's. Transients are so clean, response so even, it really does reveal how much unnecessary hash is picked up by other mics. Rejection to the rear is excellent. Can't understand why they aren't far more popular.


I have been using SR20 for both studio and live recordings. I recorded violin, viola, bass, guitar, trumpet, saxophones, trombones, flute, clarinet and pianos. Replay of the recordings with the use of B&W 800D speakers gives the sound almost undistinguashable from the live instrument sounds. xy configuration is especially nice for the piano recordings because small microphone diameter allows a pair be very close each other, so that the phase differences at high frequencies are minimal. At live recordings, these smaller and black microphones are less conspicuous. I use Earthworks TCs for percussions recordings. A bunch of my large diaphram microphones are retiring.

SR20 - A real winner.

The SR20 is a fantastic all-around cardioid condenser microphone. A pair can yield VERY accurate results when paired with a good preamp. The SR20 is an excellent choice for recording realistic sounding acoustic guitars and other acoustic stringed instruments. It handles transients superbly yet doesn't sound thin or harsh. My only complaint is that the SR20 is considerably noisy to my ears compared to a Neumann KM184 or AKG C 451 B. For recording critically quiet passages, look at the Earthworks QTC Series microphones.

Hot Mic!

This is a great sounding mic. I recieved it a few weeks ago and have used it for four gigs and some home recording. It captures the soft passages with great detail and handles high volume singing with no distortion. I unscrewed the windscreen, set it up for my acoustic guitar and recorded some of the best sounding guitar I have ever done in my home studio. To perspective buyers I say buy it. To Earthworks I say great mic, but the pop filter seems rather delicate and the case is very cheap. Both are easily overcome by taking care of your stuff. My Senheisser 431 will go into retirement. NOTE: Make sure your rig has full 48 volt phantom power. My Bose PAS has 24 volt and the mic will not work.


I work about 300 gigs a year doing mainly jazz, brazilian, latin and occasionly some pop and r n'b. I have owned many mics in the past 10 years and I tend to use only high end, top quality gear. The M69 is the best mic I've ever owned. Period . Clear, open, faithful and detailed sound. Light and elegant design. The first one I had was stolen and I can't wait to get a new one. If I ever reach some sort of celebrity I'll ask earthworks to let me endorse this mic.
