As the earbuds follow the shape of your ears, it already blocks out a lot of noise, and the ANC only makes the effect stronger.

Most headsets that have the same amount of bass, audio pickup, and noise-canceling qualities are big headsets. The company claims an eight-hour continuous battery life when using ANC, they only managed to last slightly longer than six hours. Despite the excellent ANC rating and good isolation in the upper frequencies (provided you can achieve a good fit), noise between 100-1,000Hz is not as well attenuated.I found myself on many occasions just keeping the earphones on and in, without listening to any source, just appreciating that I can better concentrate on my tasks at hand.

If you have small ears, then you might experience some discomfort because the earbuds may not fit appropriately over your ears and they may fall out if you move around too much while wearing them. Noise attenuation in the lower frequencies is very good and outpaces a lot of other capable noise canceling earbuds. Due to size and power limitations, active noise cancellation has long been a feature confined to over the ear headphones. If it’s none of these, then restart your Tozo earbuds, using the instructions in the next section below.Along with its superb noise-cancelation, the NC9 creates a great space for its vocal registers, so listening to podcasts or audiobooks sound more desirable and focused, and outside noise will be hard to distract you.

The first suggestion to fix your connection problem is to put the earbud that isn’t connecting back into the case, close it up, wait for a few seconds and take it back out to see if it syncs back up. Setting realistic expectations: the NC9 technology is not world-leading ANC that will make your surrounding world disappear into silence. Also, you will find a rechargeable lithium-ion battery pack embedded in the control pod that is located on the cord. If the volume is loud enough then unpair and re-pair them over Bluetooth, and restart the device you’re trying to play audio from such as a smartphone.Take note: The ANC on wireless earbuds doesn’t reach the level of full-sized headphones like the Sony WH-1000XM4 or Bose 700. As a general rule, the charging case could have been completely flat when you put the earbuds in to charge. I use this video for casual listening tests, as it provides bass, treble, and vocals by the incomparable Nina Simone. It is pretty much automatic after you initially pair it, which is a plus because we all know how annoying trying to reconnect earbuds feels.
