It's not the size of the boom that makes it better. It's the noise canceling software embedded in the unit. There are passive noise-canceling devices, which is suitable for most people, and the price range of these is below $60...generally.
The active noise-canceling ones cost more, and most people don't wish to pay as much for a headset, as they do their phone. But the technology is there, if you want it, and are willing to pay for it...they run above $60.
I mentioned my Blue Ant to you. It is excellent, and the price is much lower now, as it is an older model. When I bought it, it was $70. There is no cumbersome long boom...and much more comfortable to wear.
These voice activity sensors is not new technology. Noise shields are a military-grade technology originally developed for use in tanks and helicopters, to eliminate background noise in the harshest environments. But you get what you pay for. Cheap headsets will sound like crap.
