Bose QuietComfort 20 vs Brainwavz Delta

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

These earphones produce a punchy sound with a good level of detail. The bass is not overpowering, but instead is fast and controlled with good depth. The mids sound natural, while the highs sound airy without getting harsh. These should sound good for all genres of music.

For a $20 pair of earphones, these are built incredibly well. The earpieces are made out of metal which makes them quite durable and resistant to damage. The cables are soft and flexible, and shouldn't break easily.

It's easy to unpack the Delta. Just open the box and there they are.

This set can be used for talking on the phone.

These come with 3 sets of silicon tips and 1 set of foam tips. The big selection of tips play a role in the notoriously comfortable fit provided by these buds.
