Saramonic Blink900 B2 Reviews

Tough, little mics

By Juan R.
Rated 5 out of 5
Date: 2025-09-16

I’ve been using these for about two years as a daily photojournalist, and trust me, they’re solid. I’ve dropped them plenty of times, had them out in rain, sweat, dust, salty air, and heat — they still work perfectly. Signal reliability is strong, even around other 2.4GHz or broadcast RF mics at TV stations. Audio quality isn’t on par with high-end broadcast mics, but for voice at low gain and ambient at max gain, they’re excellent. The only minor issue is sometimes the mics don’t seat perfectly on the charging pins, so I’ve found them discharged a couple of times. I just make it a habit to double-check they’re charging overnight. Overall, nothing bad to say — these Saramonic mics are really good.

This plus DaVinci's new voice Isolation is amazing

I did one test so far but under very challenging circumstances. I went to a windy rooftop of an apartment building which also has a large exhaust machine for the hallway air circulation and is quite noisy. I shot the same subject at the same distance, about 8 feet, with the Saramonic 900 B2 and then another clip with the RODE VideoMic NTG Hybrid Analog/USB Microphone. Both clip where then put on DaVinci Studio with the audio, voice Isolation switch on full. Both were extremely good and so close that the shotgun mic wins in the sense of doing run and gun stuff on the street, it wouldn't be worth the extra effort of clipping the Blink on the subject. You get a quality audio with the RODE and it cancels side and rear noise so well, that when you add the audio isolate its amazing even under the trying circumstances of the rooftop I used. The Blink 900 seemed not to have quite as much bass in the voice as the Rode but was obviously much dryer than the Rode since the mic was close to the subject. In fact I used the Lav on the subject and just used the cube on myself without bothering with the lav for me. Both sounded about the same, which is great. But it did seem like the Blink has a low end cut, or it could be the mics. My question to BH would be, if I bought much better Lav mics, would the Tx Rx manage the better sound to the camera? In any case, this is a fantastic piece of kit and if you have this and the Rode you should be equipped for any circumstance you may need.
