Sony ECM-77B Reviews

Excellent Microphone

I have been using these for years. Great size, the sound from the mic is great. I use these for all my interviews. Also, the capsule is very small so it doesn't look bad on camera. Highly recommend!

Great for Basic Studios

My company has built a tiny studio in the office with many editors coming in and out and using the studio. I already have and use Sennheiser wireless lavalieres which are the best, but a problem I was having (as studio manager) was that many people were not turning off the mics which drained batteries and which costs money. These Sony mics sound great and get rid of the need to turn on/off the mics. One less thing for the team to worry about.

My Go To Mikes

I purchased 3 of these 77Bs from B&H 25 years ago and they are still going strong. I have absolutely no complaints. I have used them in the field most of the time for video production in all kind of conditions. I have used them for voice over work in the studio as well with clients even attached to a podium for my own audio feed. When I can I try to go wired because I have had some frequency issues with my wireless. My experience with the wired Sony ECM-77B has been the best over all these years. As I say, they are my GO-TO mikes.

The Standard of the Industry!

I just purchased 2 SONY ECM-77B microphones and they sound great. Last one I had lasted 30 years so as far as durability no worries. For a lav mic they are the workhorse of the broadcast industry. I would absolutely recommend them for anyone looking for a hard wired mic.

Weak Audio

By Kevin

Date: 2020-09-22

I bought this mic because of the length of the cable and the fact that it's xlr. However, I'm not sure why it gets such good reviews. The audio levels are incredibly low and the playback quality is poor. I read another 1-star review that suggested their mic was defective but I am having the same issues. This was a waste of money because I can't even use the audio.

Best microphone for interviews!

I had one for several years and now just bought another due to my need for filming more people at the same time. The mic is very solid and performs awesome without a doubt. You get 2 mic clips and one wind screen. Its good to buy an extra wind screen as they tend to get lost fast. Also, you can either use this with or without a battery.

question

Is it safe to use a NiMH battery (Eneloop) in a Sony ECM-77B lavalier mic?
Asked by: David M.
It is safe. I use them all the time. However, make sure they're not more than a year old if you're using them on critical assignments. They tend to go from 100% to flat much faster as they age.
