Shure SRH440 vs Plantronics BackBeat Pro 2

Sound signature is fairly neutral, with slight elevations to the bass, mids and highs.
Bass has a nice fullness to it, with some extra depth which gives the sound a lot of body.
The mids are neutral but slightly forward, making the vocals sound really clear. Aggressive guitars can sound a bit harsh because of this though.
Treble has good extension, and the added peak on the highest frequencies add more sparkle to the sound.
Overall, these headphones can be used both for critical listening and for casual music enjoyment as well.

The closed back, over the ear design blocks out a significant amount of noise, allowing users to easily focus on the audio. Sound leak is also kept to a minimum.
These are great for tracking and monitoring, and are also great choices for use in quiet environments like a library.

You can easily remove the cable when these are not in use, making them easy to store. This also makes the cable easy to replace when needed.

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.
