    Sony ECM-77 reviews

    ECM-77BMP Lavalier Mic with Mini Connection is rated 4.8 out of 5 by 12.
    Rated 5 out of 5 by from Tried and True I have used the ECM-77 for years in different configurations. This is a workhorse lav mic of broadcast ENG. Sound is always clean and crisp without any colouring. The capsule is reasonably small and unobtrusive. The included metal windscreen works well for its size but you do need something like a microcat windscreen to really stop wind noise. Unfortunately like most things Sony, the accessories are really expensive. It's a good thing Pearstone make much cheaper accessories for the 77.

    Rated 5 out of 5 by from A giant step upgrade! I thought the stock mic with the Sony UWP V1 was pretty good, but after hearing so much about this one I decided to pull the trigger. I had two wireless sets and needed a backup, and now this is my main mic and one of the stock mics is backup. This mic has taken my work to the next level. A very good wireless system with an average mic is cheating yourself. The richness gives that pro feel I've been looking for. A happy camper!

    Rated 5 out of 5 by from Great mic, the broadcast standard! I've been using the ECM-77b for almost 15 years now, first with Lectrosonics transmitters, then with Sony. I'm very happy with it! The ECM series been the broadcast standard for decades. If it ain't broke, don't fix it! I love the 77b because it's tiny, and the windscreen and mic clip is made of solid metal, not plastic. No coloration in sound, and very easy to hide.

    Rated 4 out of 5 by from Great size and great sound I've used this product once so far and I'll be using it in an upcoming shoot. So far so good! I particularly like the size of the mic, it's small and discreet. The sound I've captured from it has been great. The downside is that it isn't compatible with seinheizer transmitters. It only works with my sony packs. Otherwise, it's a mic I'll be using for a long time.

    Rated 5 out of 5 by from Vast improvement As with all things video no matter how much you spend you will always have to spend more. The standard mic that comes with the Sony UWP-V1 kit I found to be horrible, after some research I went with the ECM-77BMP to replace the kit mic. It is a huge improvement , sound clarity is 10/10. This was extra money I was quite happy to spend!

    Rated 4 out of 5 by from Nice sound! This is a very nice sounding mic. It's no mystery as to why many are using this on pro applications and sets.
