I hate wires, so the only solution that can give a good quality is USB RF connection.Īfter a lot of surfing, reading reviews and articles, I’ve figured out that Jabra has a good experience in mic noise cancellation, decided to buy a pretty expensive headset Jabra Evolve2 65.Īnd, victory! Results on the side talk cancellations are really great! It cancels all side voices very well! They really almost disappear! Even a colleague, that sits 1 meter to my right and talks pretty loudly, is practically not heard in my conferences! So, the solution for garbage sound quality in calls is only a wired or RF connection. Station 6: World of USB RF connection: Jabra Evolve2 devices The sound quality is great, it has 4 modes of directed capturing - that’s exactly what I need:īut does it resolve my problem? Not! I still hear all side talk, not so loud as in previous microphones, but pretty loud!Īnother fail: Separate professional microphones seems not a solution too. I’ve analyzed several reviews and bought a pretty good model - Thronmax MDrill One. Station 4: World of professional cardioid microphonesįrom audiophiles, I noticed cardioid microphones that capture sound only directly in front of the microphone. So, striking out all Bluetooth-based headsets, and go further to the next station. So, all Bluetooth headsets even in theory can’t give you a good quality sound in calls and meetings! Limitation: The Bluetooth protocol still has no normal profile for two-sided audio! There is only HSP (Handset Profile) that gives low bit rate, “voice-quality” audio, using the CVSD codec at 8 kHz sample rate, or the HSP 1.6 "wideband speech" mSBC codec at 16 kHz. I’ve bought and tested couple of more modern and expensive headsets: Apple Airpods, JBL FLEX - the results are similarly poor! Okay, maybe that headset just is too cheap? Let’s try with more expensive ones. Station 3: More expensive Bluetooth headsets I’ve bought just a regular cheap Bluetooth headset Sony DR-BT101 - the microphone is closer to my mouth, so it should work well.īut not again! The same problem - other talks are heard pretty loudly! It’s the same as built-in microphones in laptops. But canceling side noises, especially high‑frequency noises like plastic bag rustling - not for them! Station 2: A cheap Bluetooth headset I’ve bought an external webcam (Genius ECAM 8000) with 2 microphones - the results are the same! A lot of self-noise and no cancellation of side noises at all.Ĭonclusion: Two microphones are just two microphones! Even an array with two microphones doesn't give you any kind of noise cancellation at all! There is just more than one microphone, which gives you maybe some stereo effect or some other benefits, I don't know. Maybe an external webcam? They’re made for conferences, isn’t it? So, when I don’t speak, others hear a lot of background noise. I’ve replaced my old laptop with a modern pretty expensive model HP Elitebook in the hope that it has better microphones for such a price.īut the results are the same - a lot of background noise and no cancellation at all.Īnd even more - when I’m not speaking, its microphones thinks that I speak just quietly, and increase their own sensitivity, making all side sound louder. Maybe just the laptop is too cheap? Let’s try a more expensive one? Two mics, it would seem, should cancel side noise well, I thought… But not! All side noises are caught pretty loud, even louder than my ears hear them!Īnd a lot of self background noise, even in a quiet room, and keyboard clicks are too loud… I’ve started with an old good laptop ThinkPad X240, which has a built-in microphone array with two microphones. The problem: The main problem is that most of the microphones pick up all side talk pretty loud, which makes it very unpleasant for other people to listen to my voice in meetings! And the journey… Station 1: Built-in laptops and webcams with microphone array So, silence in the room is a rare situation. The environment: I work in a pretty talky office room, where sit around 10 people, and all of them have many online conferences every day, including me. And physical cancellation is implemented well only in Jabra devices yet, but other features suck them! All Bluetooth headsets suck too! So, no solution yet, just complaints! TL DR: All AI-based noise cancellations suck, only the physical cancellation technique works! It's named " beamforming microphone ".
