Plantronics BackBeat Go 2 vs Bose QuietComfort 20

Plantronics BackBeat Go 2 is among the smallest headphones ever made - all functionality is crammed within the control buttons and earbuds themselves.

To get extended use out of your headphones you can use a charging case that can be bought separately or as part of a bundle. You attach the micro usb connector from the charging case to the earbud and let it replenish the battery. A fully charged case can charge the earphones twice.

These headphones are designed to be sweatproof so you can use them in the gym, while running, etc.

The BackBeat Go 2 can pair with up to 8 devices.

If adjusted to sit correctly in your ear, these headphones give a balanced sound performance, and should work well for all genres of music.

To help the earbuds stay comfortably in the ears, there are plastic stabilizers that can be adjusted to better suit your needs.

You can get them in a bunch of different colors at Amazon.com and you can find them for less than $30 US dollars.

The BackBeat Go 2 has a decent microphone for making calls indoors, but it is somewhat lacking for outdoor use.

These headphones are ideal for long flights. In addition to having overall impressive noise-cancelling (-33dB across all frequencies on some tests), these headphones excel when you need to cancel out low frequencies like jet engine sounds (-45dB).

The headphones stay comfortably in your ear. They don't always offer a complete seal but surprisingly, this doesn't affect noise cancellation or reduce comfort. Also included are 3 sizes of eartips to help better fit your ear. Note that these tips have a unique design so you won't be able to use aftermarket tips.

These headphones have a 2.5 ft cord that's split chest high with a control module near the jack. It does a good job of not getting too tangled.

The pouch will make it much easier to bring the headphones and its accessories on the go.

You can disable active noise canceling at a press of a button. Aware Mode can be quickly accessed from the remote, which will disable active noise-cancelling and open up the microphones to allow you to hear your surroundings better.

LEDs on the control module will let you know when this mode is turned on.

These QC20 has a lithium-ion battery that promises to work for 500 charge cycles without diminished returns. After that it will still work, but won't last as long.

Note that the battery is non-replaceable so when it finally does stop working, you will need to buy a new pair of headphones.

These headphones come in 2 flavors:

• QC20 that includes a 1-button remote intended for Android users
• QC20i that includes a 3-button remote intended for iOS users
