Fit and Comfortability- This earpiece is lightweight and comfortable because it only weighs about 1.6 ounces. It will make you forget that you’re wearing the device. This earpiece is light, fits great, and even when you can tell it’s in your ear, the sound quality is amazing. The customer has said that the device is one of those must-have devices that you keep with yourself all the time. They said that it’s lightweight and comfortable as well. With the M70, you can finally free your hands from carrying or looking at your smartphone.

Connectivity- Plantronics M70 is Bluetooth connected and hence you don’t have any wires trailing off your ear. You don’t need to worry about untangling the wires while wearing it. The Bluetooth allows for long-distance connectivity of up to 33 feet from the connected device. It offers superior sound quality with noise cancellation that works very well to effectively cut out background sounds.

The voice command feature allows you to keep your hands free while on the phone or listening to audio from a compatible smartphone, tablet, or PC. This Bluetooth device eliminates background noise and an echo that would otherwise affect the clarity of your phone.

Compatible- It is compatible with any Bluetooth-enabled device. The M70 is compatible with other Plantronics devices such as Voyager Legend, CS100, CS500M, and Savi Office. You can also connect it to non-Plantronics brand devices like Samsung Galaxy S3/S4/S5/Note 2/Note 3, and Blackberry. This Bluetooth headset is compatible with most mobile phones, smartphones, Xbox 360, Kindle Fire HD, and other Bluetooth-enabled devices.

Noise Canceling- It is not so obvious that the M70 can cancel noise. It does, however, cancel ambient noise in noisy environments so you won’t have to worry about background noises while driving. You will also get an uninterrupted listening experience with your favorite music and songs since these headsets cancel any echo from the loud sounds of an environment.


Although it has excellent and promising features, there are still some downfalls. One of the biggest complaints about this product is that it does not provide a long battery life. This may be because of the noise cancellation feature, which bleeds off the battery’s energy faster than expected. Manufacturers say that you will get up to 8 hours, while other users have noted that it only produces up to 5 hours of battery.
