Do their applications need to bind personal information? I don't want my personal information to be leaked

I just purchased a pair of headphones from their family, and the connection settings application allows me to use them as a tourist, so it eliminates the registration process. Personally, I really like them and they work well. The most important thing is that they are cheap, but the sound quality is not bad at all. I bought them back and the packaging is also beautiful, which can be used as a gift.

Is there a suggested carrying case for these headphones?

Hello! Thank you for your support, Yes, we have customized this headset bag for IKF headphones. It is suitable for iKF-King/iKF-King Pro/iKF-T1/iKF-T1 Pro/iKF-T2/K2/K3 and other headphones. It is made of high-quality EVA material on the outside, and has a built-in crystal flannelette lining, which is soft and close to the skin, safe and healthy, and does not hurt the headset. It can also be a multifunctional storage bag, with built-in straps, fixed earphones that do not shake, anti-seismic and anti-pressure. Now there is a 40% discount for purchase.

It says the headphones are rechargeable. Lithium coin batteries are not rechargeable. How can this be rechargeable?

Yes, our earphones are rechargeable. You can charge and reuse them. When fully charged, when the playback volume is 30%, it can last for 50 hours, sufficient to meet the needs of daily life. Don't worry about power issues. The package includes a 3.9-foot （1.2 meter） AUX audio cable. If the headset is completely powered down, you can convert the wireless headset to a wired headset by plugging in an audio cable. If you are very concerned about battery life issues, then I can recommend the T1 Pro to you. It has a battery life of 100 hours and is an upgraded version of T1 Pro. I hope it can help you. If you have any questions, please contact us and we will reply in time. thank you very much. Best wishes iKF official store

Can voice calls work well with these other than music? i.e Teams, Zoom calls etc.

Of course, T1 supports ENC noise reduction voice calls, stereo clear voice calls, and there is no need to worry about interference. At the same time, the headset can be used for 50 hours when fully charged, which can meet daily use needs for several days without worrying about battery life.It's enough to take it with you when you go out！ If you have any questions, please contact us and we will reply immediately.
