I have found it is very system dependent whether it sounds good or not. I have used it in some setups and not liked it, and then in other setups it has been a great addition to the sound. There are also a lot of very positive reviews on Amazon:
The price went up recently to $50, but it still is not a lot of money to try it out. And with the iCAN and the Sony's, there are lots of ways to adjust the sound quickly while listening, so that makes it easier to adjust if a song comes on that was mixed in a way that the effect is too strong. I just reach over and turn off the 3D on the iCAN or reposition my headphones to shift the tone a bit as described in this post I just put up on the MA900 appreciation thread:
I want to remind anyone new to the MA900s to try playing with the position of the headphones on your head. I find these headphones respond a lot to being moved forward or backwards. It seems that moving them all of the way forward so that the slanted earpads are tucked tightly in behind your outer ear works like a tone control and shifts the center of the tone lower and calms an overly bright treble. Whereas moving them back to center or even as far back as they can go adds a lot of energy to the treble. Because of the slanted earpads and the large drivers, you can change the position of these headphones a lot compared to other headphones, as there is a lot of space inside the headphone.
With the setup I described above, I find they sound best as far forward as possible since the iCAN 3D effect does boost the upper mids and lower treble. So shifting the headphones forwards balances this out and brings back a warmer sound. This effect can work like a quick and simple EQ where you can adjust the tone to suit your mood or the particular recording you are listening to.
The position also affects the soundstage with the forward position giving the most open spacious sound. I recently read a description of Ultrasone's S-Logic that suggested much of what they feel makes the soundstage more natural in their headphones is the position of the driver. Specifically, they feel that the driver should be further forward and down low, so that the sound enters your ear canal after reflecting off of the outer ear, which is the more typical way sound enters your ear when listening to speakers or live music. So maybe it also makes sense that I like wearing my Sony's as far forward and also as low down on my head as possible most of the time. A good part of the pads are down on my cheek and jaw, so the driver is very far forward and lower than my ear. Again this especially works well now that I have the TDS202 in the system which brings out a lot of detail and the iCAN 3D effect which boosts the upper frequencies. With a different setup or on an overly bright song, a different position might work better.
It is a nice feature of these headphones that they can provide a very different sound depending on how you wear them. It is kind of like having more than one pair of headphones for the price of one!
