STAX SR-009S (new flagship)

Multilayer fixed electrode MLER (Multi-Layer-Elect-Rords) established with SR-009 has evolved to MLER 2. The finish and etching process that smoothes the edge of the electrode opening reduces air resistance and further improves sound permeability. Also, the electrodes themselves are gold plated with high specific gravity to minimize the resonance of the ultra-thin electrode. At the same time, due to the effect of reducing the electric resistance of the electrode itself by gold plating, we have opened up a new ground for high speed, clarity, silky details, and powerful texture.

SR-009S adopts a diaphragm made of ultra-thin super engineering plastic film. The light mass has realized a high transient characteristic throughout the entire audio spectrum.

The main body was redesigned to further reduce resonance as to provide a consistent sound.

ENCLOSURE:
Aluminum is a metal good for sound and suitable material for audio equipment. It is abundantly used, e.g. at the frame supporting the appearance and sound element, to realize high-quality sound, rigidity and lightweight. Almost every part of the SR-009 is manufactured through precise machine processing.

CABLE:
The high-purity copper developed from the necessity of wiring large-scale integration circuits is also known as high-quality audio cables. High-purity copper wire of 99.9999% (6Nines) purity adopted for the cable is further silver-coated and finished with the most suitable structure to drive the earspeaker.

EARPAD:
The earpad of a new design is carefully made by a craftsman's hand and features both the real leather with good humidity environment and the cushion material with moderate elasticity.

The new earpad enables hours of comfortable listening to music.

ARC (head band):
The arc is equipped with a position adjustment mechanism of 10-step slider and corresponds to the wide range of cranial form with individual difference.

Just Buy It
This smells AMAZING! The body butter smells amazing too but the oil smells so much like the Vanilla Amber Sand+Fog oil perfume. I’m so glad I have all three and went ahead and picked up some Vanilla body wash. My kids said I smelled like a bakery all day. I couldn’t stop sniffing my arm and clothes the scent sticks and such a wonderful combination to my perfumes that has vanilla notes. Also, makes your skin feel awesome after a shower. It’s not so greasy after application and gives your skin a beautiful glow in the light. BUY IT!

Size: 6 Pairs - 6 Colors Assorted
Works great for myself & hub! I bought them mostly for him because his feet are wrecked, but it’s a 6 pack, so yay me. The cushiony heel was a bonus I didn’t expect, so nice + comfortable to sleep in- usually hate sleeping in socks but since your toes are free, these do not bug at all. Definitely get these

Go buy these heels socks they’re the best
Size: 6 Pairs - 6 Colors Assorted
I love that they have gel in the heels. I sleep in a pair and even wear a pair to work for extra protection for my heels. They are great to get your heels soft and prepared for the sandal wearing days of summer. They slide on my feet so comfortably because of the great stretch they have. I just love how they feel on my feet , walking in them is very easy and comfy and they don’t slide or is slippery. You can even wash them like regular socks and wear them over and over. I would recommend them to anyone who wants baby soft heels.

Love these
Size: 6 Pairs - 6 Colors Assorted
These are fantastic if you want a 'foot mask on the go'. They fit easy, the colors are great, and they work! I used them after putting on moisturizer and my heels were smooth and looked great in sandals after! No cracks or dry patches!
