Sennheiser IE 100 PRO NEGRO

These headphones are superb. The sound quality is top notch with tactile buttons to control them. Battery life is, so far, good and I like that you can swap the bluetooth module for the included wired connection. The fact that they stay in your ears is a huge bonus too.

Love the sound - but you need to stay close to your source - probably due to on-stage use via wireless links. I've not experimented with the different ear tips yet - but I've not felt the need so far.

the item was supposed to be new in damaged packaging from amazon warehouse. the wifi cable has traits of very heavy perfume in it i am struggling to get rid of. amazon were kind of helpful and rectified with partial refund, however, after reflection it is still not acceptable. other than the state of the wifi cable, the actual headphones work well and i am happy with fidelity.

The earphones are a good fit I think and they stay fixed around the ears well with a good bass sound I find.

Many dislikes about these headphone given the price. First off, sound quality was OK but not great at noise cancelling nor are they that loud The controls are too close to the ear to swing around like a set of dangling earrings. The charger port has a little rubber tab to open which keeps out dust and water. It's impossible to open without a small tool such as tweezers. Eventually the end of the tab snapped off and now I cant open it all. And 5 months in one headphone has completley cut out, now the other one is crackling so I will say finally, not pleased.
