Sorry,  I ment lower impedance as in a four ohm speaker has a lower resistance to electrical current than an eight ohm speaker. Therefore, a four ohm speaker will draw more power from the amplifier than an eight ohm speaker.     kill me...

 Impedance is how you get more watts into a speaker and that does correlate to visceral.   There are also other factors that make up a great speaker, but to say  "impedance doesn't correlate to visceral in any way" is just wrong.   Re the SE-846, keep in mind that, along with 9 Ohm rating, ...

It is very simple.   The lower the Ohm number value, the higher the impedance.    As you add more speakers/armatures to an IEM,  the impedance goes up , and in turn you need more amps to drive the enclosure  at the same voltage.      This is not exactly the case with the SE-535 which are...

If you plan to drive these off of your Iphone 5 - without an amp,  the 535s may be a better choice.    I am very happy with the iphone 5 and my 535 set up.   Re: the SE 846, 9 ohms, this is unheard of  resistance for an IEM.    Sonically  this is a good thing, as most of you know.   With the...

Specs are impressive!   Almost half the Impedance of the IE-800s   Impedance:   Sure 535                      36 Ohms JH-16                           18 Ohms Sennheiser IE-800       16 Ohms   Sure 846                        9 Ohms

I am a huge fan of the 535.    I have been using a pair in  clear for 2 years now.    I fitted these with the Comply P-Series Slim Foam Tips.     As we all know, fit and sound quality are subjective.  Now add to that other variables such as the  type of music you play and your rig, and nobody is...

Spyro,   UE900 are really sweet.   Nice design as well.    If I had purchased these,  I would not have spent the dough on customs.  Do you have a pair?   Have you played with the Arrow 4g?   Thinking about that gem.   -VL      

I have the Westone 4s and many other excellent IEMs in my growing collection.   They are all so different that it is hard to rate them without taking into consideration so many factors.  To name a few,  1) the type of amp(s) used, 2) style of music, and 3) personal taste ( the dark horse in this...
