Introduction

The TOZO NC2 fully wireless headphones are well-made. They have a battery life of over 10 hours and come with a case that can contain three more charges. Because of its somewhat v-shaped sound profile, your music will have more rumble and punch, while instruments and vocalists will seem more present and brilliant. They don’t have an equaliser, thus you can’t change the sound. They have a dismal and inadequate active noise canceling (ANC) function, especially when it comes to filtering out bass-range noise like rumbling motors, unlike the TOZO NC9 Truly Wireless.

Truly Wireless Active Noise Cancellation Technology

With the technology of Earbuds, you can select compatible communication devices without using cables. Earbuds do not require keeping the phone facing earphones directly, but the maximum distance between them should not exceed 10 meters (about 30 feet).

Using active noise cancellation technology, the microphones collect the noise, then the acoustic engineer calculates and designs a series of software and hardware algorithms, the circuit generates a reverse sound wave that is opposite to the noise and emits it through the horn. Finally, the noise and the reverse sound wave cancel each other.

Frequently Asked Questions

  • Do these support aptx/HD? 
    I don’t think so. Acc & sbc is getting better that’s why a lot of new headphone does not need them nowadays. I might say aptx is passé especially when a lot of people are using apple products. Even SBC is getting better.
  • How deep do these fit in the ear canal? I have the too nc9 but the push was too deep in my ear and hurt after an hour. 
    This is a bit difficult to answer in consideration of the different sizes of individuals’ ears. Though these are very comfortable in my ear and don’t go too far into my ear canal. Again my ear and someone else’s ear may differ. That’s all I can offer.
  • Do these have in-ear detection? 
    In-ear detection works good for me, works if I pull either one out, or if I’m only using one, still works, and usually resumes when you put it back in your ear. It does get confused if I pull the left one out(it pauses) and put it in the case and leave the right one in.
  • Do these work with Google voice assistant? 
    Yes. If you have a Samsung phone though, Bixby might try to launch instead of Google Assistant. I have a Galaxy Note 20 Ultra, and I had to completely disable Bixby before it would let me choose Google Assistant as my preferred voice assistant with these headphones. This is more of a criticism of Samsung though.
  • Can I turn off both anc/transparency mode? 
    Yes, only when you start it. Default is none then anc or transparency only.
