Lieven posted a review of the newish ER4-XR and SR IEM over on Headfonia. They have a bit of a bass boost from the original ER4-S. Read the review of the for your by clicking the link below. Personally, I’m sticking with my 2003 ER4-S and if I need more bass I’ll EQ it. Interestingly, the original S and P models are going for about the same price as the XR and ST models.
Nathan posted a review of these IEMs over on Headfonia. From the review it appears that that these IEMs have a pretty flat presentation. The vocals shine but you don’t have bass of other IEMs such as Noble’s K10.
LIEVEN over on Headfonia posted a review of the quad-BA plus dynamic driver IEM. From the review it sounds like LIEVEN really liked this flagship IEM. Likely due to the dynamic driver, the A91 has bolder mids and bass than some comparable BA only IEMs. Pop over to Headfonia and read his complete review.

Nathan posted an extensive review of the BE6I IEM over on Headfonia. Sounds like they are a reasonable product at the sub-$150 price range.
Lieven has a wonderful review of the new HD800s headphone on Headfonia with extensive comparisons to the original HD800. I agree with Lieven that the HD800s is reaching out to a broader market by bringing out more lower mids and bass. I recently compared the HD800s with my original HD800 and have decided to keep the originals. Read the review and see which headphone Lieven likes more.
