If you only use one earbud dows the other one work if u have the main one on

Thanks for your question. CX 400BT True Wireless earphones deliver stereo audio via their left and right earbuds. However, the user can use the right earbud, which serves as the ‘master’ earbud to establish the connection to the paired Bluetooth device, as a stand-alone unit for phone calls and voice assistant access. World Wide Stereo is 42 years old and a proud authorized Sennheiser dealer.

Will these work with my smart tv in place of the sennheiser headet i’m currently using?

If your smart the has blu tooth it should.

Are these good for taking calls?

They are OK at best for taking calls. There are better options for that but these will work. Sennheiser is more about great sound quality for music.

How do I find wireless earbuds for my android phone motorola?

These should work fine with your Motorola phone as long as it is a recent enough model to have Bluetooth. Actually, your Motorola phone, if it has Bluetooth will work with just about any wireless earbuds.
