Arctic Sound E461 Earphones @ reviewstash.com
 

Just six months ago, we took a look at Arctic Sound's E361 earphones.
They were not only stylish and affordable, but also capable of
producing enjoyable, accurate sound. Barely half a year later, Arctic
has us taking a look at their newest earphones - the E461. Compared to
Arctic's previous product, the E461 costs $27 more (49.95 vs. 22.95),
features lower sensitivity and impedance, but has slightly better
frequency response for the low-end. Lower impedance means that the
unit will be more efficient in using electrical energy, whereas lower
sensitivity implies that the earphones need more power to sound loud.
On paper, these two items should balance one another out. Hopefully,
however, the E461 proves to be a solid upgrade to the existing E361.
The improved low-end (on paper) is a certainly welcomed addition.
