Plantronics BackBeat Pro 2 vs Sennheiser 4.50 BTNC

With the BackBeat Pro 2, you get powerful yet clear sound that is comparable to higher end models but at a noticeably more affordable price. Wireless range and stability is quite good and the noise cancelling, while not the best, can reduce a good amount of external noise.

While the active noise canceling is not the best, it is able to reduce a good amount of noise from your surroundings. Loud engine sounds or high pitched noise may still mix in with your music though.

The BackBeat Pro 2’s mids and treble are not forward, yet sound clear and neutral. You may hear a bit of sharpness in the higher frequencies, but overall you’ll get a pleasant listening experience with great details from your music.

The low-end is quite emphasized, so you’ll get a lot of thump from bass hits. Bass lovers will likely find these headphones to be up their alley.

You won’t need to press a button on the headphones or on your source device to pause the music when you need to remove the BackBeat Pro 2. There are sensors inside the headphones that detect this motion, so the music is automatically paused, and then resumed when you put the headphones back on.

Listen to the environment via a microphone without taking off the headphones.

These headphones have Bluetooth connectivity for wireless convenience, but you can also switch to 3.5mm wired mode if the battery runs out and you cannot charge right away.

You’ll be able to hear audio even if you are around 100 feet away from your source device, provided there is a clear line of sight. Signal quality is also pretty good with minimal music cuts and drops.

These headphones can last up to 24 hours of playback from a full charge, and this with moderate volumes in wireless mode with noise cancelling activated. This is very good battery life, considering other wireless headphones at the price range only have around half the battery life on average.

The active noise cancelling feature can reduce a good amount of ambient noise that may mix in with your music, though it doesn’t completely eliminate both high and low-pitched noise if they're loud enough.

The headphones can last around 19 hours from a full charge on wireless mode with noise cancelling on. When on wired mode, it can last 25 hours with noise cancelling which is pretty decent for its class.

These headphones can easily fit inside a bag or purse, and should be easy to carry. The ear cups can fold up to the headband, reducing the headphones’ overall size.

The mids of the 4.50 BTNC sounds natural and clear. Music with a lot of vocals and guitars will definitely sound great with these headphones. The bass is not very powerful, but still provides a satisfying thump to the music. Overall, these headphones sound warm and laid back, great for casual music listening.
