Performance

Since the Pro|Tones m250 are not made for gaming I have decided to test the general audio performance only, by listening to a lot of different types of music - all the way from classical over techno through rock. The attributes I listened for were a clear and precise treble and bass, as well as a well balanced output. The Pro|Tones m250 features a little Razer innovation called True Bass, which should boost bass performance of the headphones.

To test the performance of the m250s I used my Creative Muvo 2. Besides that I tested it with my Creative X-Fi Extreme music. When testing the definition of treble and bass I used MP3 files with low compression ratios in order to maintain all of the definition of the original wave file.

The general audio performance of the m250s are nothing like that of the Razer Pro|Tones m100s. Where the m100s are good the m250s are great, where the m100s are great the m250s are incredible. The definition of the treble with the Pro|Tones m250 is nothing short of amazing, compared to the size and cost of the headphones. When it comes to bass performance, these won't let you down. The bass has plenty of power and definition to make bass intensive music come to life.

One of the hardest qualities to gain in headphones is a balanced audio performance. I think that the Pro|Tones m250 are well balanced and has an exceptional treble, the high tones are precise and warm. This is great because the most mainstream headphones tend to have a precise but metallic sounding treble.

Comfort

Once you find the correct way to fit the Pro|Tones m250, they become quite comfortable to wear - even over an extended period of time. They seal your inner ear quite nicely, while still letting some surrounding noise and fresh air pass through, therefore they don't make your ears heat up like ordinary closed headphones.

Durability

The m250s are based upon a metal outer casing which should improve the overall durability of the headphones. The inner side of the Pro|Tones m250 is made of plastic and has some soft foam padding. The only weak point of the design that I could identify, is the clip. When it's extracted, it seems to be quite easy to tear off. This of course, is highly unlikely because the only time when the clip is extended is when you are putting the headphones on. I think that the headphones are quite durable when the clip is folded.
