I bought Sennheiser HD600 and returned them immediately. They were very uncomfortable for me and completely lack of bass. I was very disappointed. I like warm sound and a little bass. Your review about HD630 is very positive. You did not mention about how comfortable they are. I was going to buy Sony MDR1A because they are very comfortable. Is HD630 or MDR1A better choice?
Thank you again for helping me making a good choice. I really appreciate it.
I'm really sorry for your bad experience. I avoid saying anything about Sony because I never heard them or wore them on my head. FWIW, I wouldn't recommend something I have no experience with.
However, saying that HD600 lack bass is a bit strange to me. I went on to read a bit about them and found these specs:
Frequency response: 16Hz-30kHz, ±1dB. THD: <0.1%.
Nominal impedance: 300 ohms.
Sensitivity at 1kHz: 97dB.
Headphone caliper pressure: approximately 2.5N.
Now, if they extend anywhere near 16Hz, and Sennheiser doesn't really cook their books, you should have bass-galore. Some reviewers say that the bass is not pronounced and that HD600 is a neutral and good resolving model. perhaps it's that.
But to lack bass, I would be quick to blame the impedance, but I leave that to bigger experts.
I recommended the HD630VB model because they are suppose to go down to 10Hz according to Sennheiser site. And they have Bass Boost +/− 5dB at 50 Hz.
Having said that, I've noticed that most of the over-the-ear models from Sennheiser have a similar shape of cans. If this is somehow uncomfortable to you, it's possible other models will be uncomfortable as well.
Of course, regardless of any advice, you should always test them before buying.
