MEEaudio A151 IEM (2nd Generation) Preview PRE-MEASUREMENT SUBJECTIVE NOTES Just some quick impressions before I throw up measurements. A touch bassy with UERM like middle and upper mids (call it DF tuning, or not). I didn't have a problem getting a good seal with the stock provided tips. Note that the nozzle diameter size is very small. Bass was strong from the mid-bass down to the sub regions. The bass did not intrude into the midrange at all. A peak somewhere just below the silbilance region, which should be around 7kHz. I can't decide if the mids are recessed or not, but I think it's more a matter of the mids in relation to some elevated peaks around 3k and 7k. Just a guess. The FR irregularities are easily bearable for me, considering the $40 street price. I do prefer these from my warmer more laid back sounding Sony X (or warm sounding laptop outputs) than from my phone which is more neutral. The Sony X also happens to have EQ sliders at 2.5k and 6.5k which can be moved a notch down. Impressive plankton retrieval, but doesn't have quite the clarity of UERM or Jupiter. There seems to be a veil throughout the entirety of the audio band. Bass is murky. Would be interesting to see distortion plots. Stage is flat and two-dimensional. Stereo width is good and overall stage isn't closed in or constrained. At $40, a very good value.
