ETM Series, EIM Series? What are the differences between two different product lines?

The ETM-Series microphones are a 3.5mm 3-pole (TRS) electret condenser microphone designed for the devices with a TRS jack such as GoPros, camcorders, DSLR cameras, PCs and audio recorders.

* For GoPro® Hero3 or later models you will need a proper GoPro 3.5mm mic adapter.

The EIM-Series Microphones are a 3.5mm 4-pole (TRRS/CTIA) electret condenser microphone designed for the devices with a TRRS jack such as iPhone, iPad, iPod, MacBook, iMac, Android Smartphone and Tablet.

** For iPhone 7 or later iPhones, you will need a 3.5mm to lightening adapter. 

What is the difference between similar-looking microphones on Amazon and eBay and Edutige microphones?

There are several significant differences. First of all, Edutige microphones are built to last, made from brass, whereas other mics found elsewhere are plastic.  Second, quality. Inside, Edutige microphones are carefully assembled like a fine watch. And something else you won’t find with those cheap mics is a 1 year warranty from date of purchase.

What kind of warranty is there on Edutige microphones and accessories and what is your return policy?

Your items are protected by our 30-day money back guarantee and 1 year limited warranty. Please see our Returns and Warranty page for all the details.

What are the differences between ETM-001, ETM-006 and ETM-008 microphones?

Edutige Dual Microphone ETM-001
The ETM-001 is a high-sensitivity omnidirectional microphone that captures sound from all directions and boosts the volume of your audio recordings. The ETM-001 is a general purpose plug-in and play mic good at capturing sounds at a distance.

Edutige Lavalier Microphone ETM-006
If you need a lavalier microphone, the ETM-006 is the one. It is a high-sensitivity, omnidirectional microphone featuring the same technical specifications as the ETM-001.

Edutige Unidirectional Microphone ETM-008
The ETM-008 is a unidirectional microphone, capturing sound from directly in front of the mic and rejecting ambient sounds. This is perfect for anyone who makes videos because you will only get the sound you want to make your video sound awesome. The ETM-008 also comes with a 4.3ft long extension cord and lapel clip so you can use it as a lavalier microphone.

How can I reduce wind noise in the recording?

We have the furry windscreens specially designed to reduce unwanted wind noise when recording outdoors. 

Do I need a battery to operate the microphones?

No batteries are required. The power supply comes through your recording devices.

Can I use the ETM-Series microphones with iPhones and other smartphones?

No. iPhones and most smartphones today has a 3.5mm TRRS audio jack, so you will need an EIM-series microphone. But you can use the Edutige ETG-003 TRS to TRRS adapter to use the ETM microphones with the iPhone and other smartphones.

What are the differences between EIM-001, EIM-003 and EIM-0?

EDUTIGE iMicrophone EIM-001
The original EDUTIGE iMicrophone for the iPhone, iPad, and other Apple products. The EIM-001 is a highly sensitive microphone, boosting the volume of your audio recordings and is perfectly suited for meetings or lectures when you can’t get close to the source.

EDUTIGE iMicrophone EIM-003
The EDUTIGE iMicrophone EIM-003 is originally designed for monitoring music. Features a flat frequency response and high signal-to-noise ratio for clean, original sound in your recordings. The EIM-003 is the perfect mic for monitoring music, recording something you want to share with customers or clients like a presentation or screen capture video, or for external audio for your iPhone videos.

What is the difference between the EIM-001 and EIM-003?

The EIM-001 is for getting a louder input volume compared to your Apple device’s built-in microphone. The EIM-001 is the ideal mic for recording lectures, business meetings, or any situation where the person can’t speak directly into your device.

The EIM-003 is specially designed for monitoring music. The EIM-003 is also great for recording audio for video because it captures sound in it’s natural state. You will notice that the EIM-003’s recording volume is no higher than the Apple device’s built-in mic, but the captured sound will be much clearer and cleaner.

Do the EIM-Series microphones work with the iPhone 6?

Yes, they will work with the iPhone 6, iPhone 5/5s, and iPhone 4.

Do the EIM-001 and EIM-003 work with Android phones?

Yes and No. Android is open source. The phone manufactures and app developers change their interface with external microphones on their own discretion. Therefore, it is nearly impossible to predict what they will make changes to each upgrade to the hardware, OS, and recording apps. As a result, the recording quality widely varies between devices, OS, and apps. Direct testing will only assure your phone’s compatibility with the mic and it is always wise to ask us if you are not sure.

Do I need an extension cable to use any of the EIM-Series microphones?

No. All the microphones are designed to work by plugging them directly into your device.

However, you may use our ESL-Series extension cable to extend the reach of the microphones, useful when recording audio for your iPhone videos. If you are a musician or need to fine tune your audio, you may need the ESL-001 and ESL-002 cables. These extension cables feature a built-in volume control and earphone/headphone plug. Please note that you need a recording app that supports the external monitoring such as Apple’s Garage Band or FilmicPro.

How can I reduce noise in the recording?

Sometimes, noise can be caused by interference from your device or other nearby electronic equipment. In particular, interference from digital signals from cellular networks can cause noise.

Some tips to reduce or avoid noise are to always switch your device to Airplane Mode and unplug any unnecessary electronic equipment in the room. You can also try different recording apps. We recommend ClearRecord, as it features an ambient noise reduction (ANR) setting.

If you’re using the microphones with your laptop, try unplugging your laptop while recording because interference from the outlet can enter your recording.

When you recording outdoors, the EWS-003 Furry Windscreen help block or reduce unwanted wind noise.

Which microphone should I use for recording music or singing with my iPhone, iPad, or iPod Touch?

The EIM-003 would be best, but if you’re recording very loud music or drums, then go for the EIM-004. Unfortunately, the EIM-004 is out of stock and no long in production.

Can I use my phone’s built-in recording app or do I need a special recording app?

The built-in recording app, like Apple’s Voice Memos app, is fine since it’s the easiest. However, if you want a little more control over the recording in terms of quality, then try a special recording app.

In the product demo videos here on the site, ClearRecord was used. ClearRecord works well because it has an ambient noise reduction (ANR) setting. Others such as Fire, Recorder Pro, VoiceRecord, Griffin’s iTalk, or even Apple’s GarageBand would also work.

Can I use Edutige microphones for podcasting?

Absolutely! We recommend the EIM-003 since it works well up close to the person speaking and has a lower noise floor. In addition, here are some tips for getting good quality sound for podcasting when using an Edutige microphone…

  1. If using a laptop, unplug it before recording.
  2. When using your mobile device, switch to Airplane Mode to reduce interference and to avoid unwanted calls or messages while you’re recording.
  3. If using your iPhone with the EIM-003, keep the mic about 6-10 inches away from your mouth.
  4. For the ESL-001, clip the microphone about mid-chest level or slightly lower.
