    ECM-77B - Miniature Omni-directional Lavalier Mic is rated 4.8 out of 5 by 50.
    Rated 5 out of 5 by from Overall, VERY good mic As a local news photog. I have used the same ECM-77B mic for over 10 years through the extremes of Chicago weather without a problem. I am of strong belief that audio should be heard and not seen, and these mics allow for a great compromise of sound quality and size. I know there are better sounding lavs, but the ones I have experience with have been too bulky for my comfort. I take care of my gear as best I can, and as I've said, brutal winters, humid summers, strong wind and rain, and the abuse of local news and reporters have not stopped this mic from working problem free.

    Rated 5 out of 5 by from My go-to lav mic I've used the ECM-77B to record about 35 documentary-style interviews in the past year. I'm consistently impressed with the quality of recording it produces. I don't want to speak to its noisiness in any way because I think it varies depending on your setup, but I use it with a Tascam digital recorder and post-produce the audio in Audition with the iZotope noise correction VST. It feels like, no matter which boom mic I use, and no matter how much I post-produce a recording from another mic on the same set, the ECM-77B recording is always my #1 choice for dialogue tracks. Strongly recommended.

    Rated 5 out of 5 by from Went out and bought a second one the next day We bought this lav to shoot web videos including interviews and comedy sketches. After our first shoot, using our shiny new ECM-77B on one actor, and a borrowed lav (can't recall the model) on the other, we immediately purchased a second ECM-77B. The sound quality was incredibly superior. We had listened to it live in the booth at B&H and loved the sound right away compared to it's competitors, but after ingesting our footage we were even more pleased. The mic delivers a crisp, full sound at a reasonable price. The head and clip work so well together, never picking up rustling or unwanted noise.

    Rated 5 out of 5 by from Industry Standard for a Reason I've use the ECM-77B for broadcast journalism, documentary filmmaking, and have even used it for off-camera voiceover work. Totally solid build quality, small and inconspicuous to use, and the sound is flawless. It's worth mentioning that the semi-hardshell padded case it comes with is a huge perk of the mic - it keeps this little guy safe when you're schlepping around gear to & from shoots, projects, etc.

    Rated 5 out of 5 by from Great Lavalier Mic I bought this mic as a second mic for my video production business. My main lav mic was the Sony ECM-77B, which I've had for years. It provides great sound for interviews. I recently had a shoot where I needed to mic two people so I bought another ECM-77. This mic is definitely durable and lasted much longer than the wireless mic I owned. I use it with my Canon XF300, powering it thru the camera's phantom power. Excellent mic, worth it's cost.

    Rated 5 out of 5 by from THE industry standard I've had my Sony 77B's for 20 years. They have been through hurricanes, ice storms, and snowstorms. For 10 years I was a network news photographer and did numerous live shots and all day coverage for a cable network. My 77's NEVER failed me. I've got Trams that are susceptible to RF interference. When the Tram fails, I know my 77 will save the day. Time to replace them as the wires are starting to fray near the capsule.

    Rated 3 out of 5 by from Pricey industry standard This is my field lav. I like it for its durability, long cable and epic battery life. Its sonic characteristics and quality are acceptable but don't compare favorably with comparable units from Sonotrim, Voice Technologies or Tram, specially in terms of price. Additionally, their accessories are also pretty pricey. Overall, a satisfactory mic, but you are paying a premium for the SONY name.

    Rated 5 out of 5 by from Reliable and great quality sound We use these microphones for weekly scheduled webcasts of our product presentations and product launches. These webcasts are initially presented live, but are recorded for internal on-demand viewing. The Sony microphones have great sound quality and are very small so they are not distracting to the viewer. I have never had an issue and these microphones are easy to use for our sometime novice guest presenters. I believe it is better to pay a little more money for a product that is going to provide good quality and last for a long period of use.
