Good Headphones for electric keyboard?

[gleeok]

Yeah, my earbuds broke. Although they weren't meant for this kind of use, they had a very good isolation which helped me to practice, suppressing the sounds of my noisy family.

I have a beginner yamaha psr-423, which I will not only use for classic pieces, but also a bit of mixing/synth and keyboard-like music (beat+melody*).

Which headphones would you recommend for my case? Are there good ones with a decent isolation? It makes difference in the sound if I use one specific for the big 5mm jack or a 3.5 one with a 5mm out adapter will do?

(does this have an specific therm in english? I have no idea on how to pass this to english lol)*

I'm really thankful for any suggestions I get, I have no idea where to start. I'm good with picking earbuds for portable use, but for this I really have no idea..

i think some of the better inexpensive 'noise reducing' ones are the jvc marshmallows, i love my little ones i use right now, the cord could be a little longer but it is long enough for this use.

More money equals better sound. Spend as much as you can. I use battery powered noise cancelling over the ear head phones which were very expensive. They keep out distracting noises so I can concentrate.

Generally speaking, better sound can be had by open back headphones.  If you want noise canceling properties, you do sacrifice some sound quality for that feature.  As mentioned above there are also headphones with active noise cancelling. 

Some headphones that I have tried, and liked for piano listening include:

Denon AH-D1100.  Closed back, with some open properties in the sound.  There is somewhat of a tenor/bass boost, so if you like a thick bassy sound you may be interested in this.  If you can afford the more expensive headphones in this series, go for them. 

Sennheiser HD 518.  Open back.  Very good soundstage with flat response.  I very much like the Sennheiser sound for my listening.  Open back means that ambient noise is let in, but with that a much greater sense of sonic realism.  If you can afford headphones higher up in the 500 series, or even better the 600 series, these are really excellent.

I'm not much for ambient sound while I'm practicing. I seldom have the luxury of being totally alone.  I'm using Bose both for my piano and on the airplane. It's really up you.

Bose? Mind telling which model? Thanks for the suggestion.

Quiet Comfort 2. That was a model when they first came out. They're still doing fine. I often practice in very noisy surroundings. These cut out everything except a person talking nearby. On the plane I only hear the P.A. No engine sound.

They have a switchable input which seems to match every source.
