Sennheiser HD380 Pro vs Shure SRH440

The tight clamp on the 380HD helps create a seal that prevents quite a bit of sound leakage.

These headphones, as far as reference or pro-quality headphones go, are fun sounding. There is a slight boost to the lower frequencies which adds fullness and depth to the bass. The mids are also full-sounding, but there is a peak at the upper mid frequencies which can make guitars in heavy music sound harsh. The highs have good detail to them, but the peak in the top frequencies can also make the sound a bit grainy.

The 380s sit well over your ears and do not typically touch them when positioned correctly. This helps make them comfortable as the clamping force is distributed over a wide area, not directly on your ears.

The HD380 Pro is quite portable thanks to the detachable cable. Also, the included cable has a specially designed locking mechanism which prevents it from being detached accidentally.

The HD380 Pro can produce great sound even paired with low power amps. Some headphones require expensive amps to sound properly, but for these, even entry-level portable amps are sufficient.

These headphones can easily be brought along while traveling and spending time outdoors thanks to the included carrying case. The solid, clam shell design gives the headphones extra protection from impact and scratches.

The large ear cups and the strong clamp allow for impressive passive noise cancellation.

These headphones have fairly wide soundstage, despite being closed back.

The ear cups of the HD380 Pro can be folded up into the headband. This reduces these headphones' size and footprint, making these much easier to fit inside a bag.

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.
