Are the different specs compatible with each other? Yes, but subject to certain conditions. If, for example, you have a laptop with version 4.2 and a headset with version 5.0, the pairing will still be successful, but the data transfer rate will be markedly reduced. Therefore, buying headphones with the latest version of Bluetooth makes no sense if the laptop has an earlier specification. Connecting TOZO Wireless Earbuds to a Desktop PC The NC9 has definite room for improvement with it’s voice microphone and voice call capabilities. Microphone performance seemed adequate for casual calls, though I would not recommend them for professional/business calls. My guess is that it may be a cost containment measure and not a priority to include CVC technology. There is no ANC for the onboard microphones used for voice calling.

SOUND QUALITY: The T12 has the typical sound found on most Tozo's earbuds, but executes it the best. You'll find a warm and energetic sound, helped a strong, thumpy and surprisingly deep bass that will have your head nodding before you realise it - although, mind you, it can become too loose in bass-pushing songs.
