The Sennheiser HD 380 PROs are headphones that are great for use in situations/environments where silence is key. Their closed back design is very effective at minimizing sound leakage so other people will not get distracted by the sound produced by these.

Pros
Pro Fairly natural sound with slightly boosted bass
The bass is slightly boosted, adding good punch and thump to low-end sounds without overpowering the other frequencies. The mids are natural and forward, while the highs have good clarity.
These headphones can work well with a wide range of music genres, though rock and pop music are the ones that these will shine the best in.
Cons
Con Very strong clamping force
The 380HDs have a very strong clamp. This helps the headphones achieve better sound isolation and minimal sound leak. Although some will find the clamp very uncomfortable. Fortunately there are also many who will never notice this at all and find the 380HDs very comfortable.
