While there are a lot of good wireless earphones out there, some can be really bad. Choosing the right pair of wireless earphones can be confusing. It's important to choose the right pair for you.

Don't go for cheap ones 

Cheaper wireless earbuds use low quality Bluetooth chips that create a big delay in audio transmission. Such delays are more noticeable while watching videos and playing games on your smartphones. Moreover, cheaper models often use poor microphones. Making or receiving calls from such earbuds can be a mess.

The codec is critical

A codec determines how audio is transmitted over Bluetooth, from the source to your wireless earbuds. It encodes and decodes digital audio signals for faster and reliable wireless transmission. A pair of good wireless earbuds support codecs such as aptX, aptX HD and LDAC 900. These codes are far better than SBC codecs due to their lower latency and support for faster bitrate.

How about battery life?

If a device claims a battery life of 10-12 hours, expect the real-world performance to be lower by an hour or two. Also, batteries on some basic wireless earbuds may wear-out quickly which can drastically reduce the device’s lifespan.

Noise cancellation

Most noise cancellation earbuds also come with a “Hear through” feature which by a single touch, lets you hear what people around you are saying, without removing the earbuds. Having noise cancellation on your wireless earbuds improves the audio experience, however it can drain the battery quickly too.
