If you want a fantastic "pop" to your music with a fun sound, do try the DT990s. They have a big wide soundstage with incredible bass, extremely analytical sound. However, for a safer option just go with the the 600 (neutral) or 650 (slightly warmer + more bass) from sennheiser.

Hi all, sorry I hadn't had the time to respond, was quite busy. I'm using a DT990 pro 250 ohm with a fiio E07K as the DAC and and iCan Micro as the amplifier. Frankly, does the mids sound good on the HD650? Yes! It's sounds great! No arguments there at all. However, what gets to me is the...

Do give the DT990 a shot? They have plenty of clean tight bass

I own a DT990, and yes the treble and bass is accentuated, but the mids are still great!   However, I cannot emphasize this enough. You need a good amp + high quality source files in order for them not to sound sibliant. 

Actually I just went to audition HD650 yesterday, and I found that I still much prefer the DT990.   I've realized that the HD650 vocals is really right in your face, whilst my DT990 is slightly pulled back and sounds further away. However, I felt that the instrument separation and bass on the...

Personally, I would go with the 250ohm and save some cash. The 250 does have a higher clamping force, but you can always stretch them out using books. Also, the velour pads are really comfortable, and thus the higher clamping force would somewhat be negated. Also, the 600ohm ones would be much...

I'm glad you've decided to move up to the HD600! I'm also planning to upgrade to the HD650 after a few years after saving and scaling up my setup and my files , but now am extremely contented with my DT990 along with the 320 kbps songs. Hope you enjoy the HD600!

Hmmm Okay, you can choose to believe that, and I respect your opinion that a better amp will not make any difference. However, there are many reports that said otherwise, and it is up to you to believe in them. Furthermore, nobody is denying that the DT990 do accentuate the highs and the lows...

As mentioned by some of the members here, you have to understand that different headphones for different types of people. For example, you cannot expect to buy a HD800, leave it unamped, use poor quality sound files, and expect it to sound awesome. Even though the headphone is fantastic, the...

I would recommend that to get a slightly better idea, you should look at the frequency response curves of the individual headphones. They can be found on websites such as head room. However, the best judgement wound be reserved for you to simply audition them yourself. You need to understand...

Try the COP from Beyerdynamic or the V-modas

Hmmm there have been people saying that the schitt magni+modi combo is pretty good, whilst others recommend the O2 combo. I personally never tried both of these, and thus cannot comment on their quality.   However, I bought the Fiio E07K as my starting amp/dac combo, and felt that it was a...

Yes that's true. However, the OP was looking for a headphone that would still provide a kick even whilst using an unamped source, so I felt that the COP were probably the best way to go.

No worries at all haha, glad to always learn something new everyday :) This is a pretty wide misconception that many, including myself had, and thanks for clearing it up!   Haha okay, let me rephrase my conclusion then, DT990s would sound great with an amp with a warmer signature :)

Nope, there is no tube in the iCan.   However, the sound signature, I feel, is warmer as compared to the traditional solid state amps.   The rationale behind me recommending tube amps is simply because they tend to be warmer sounding, and that IMO gives the DT990 an awesome sound.
