Pioneer leverages over 70 years of audio know-how to deliver an audio DNA specifically designed to emphasize what's most important to the dancer--the beat.
Engage your music
The same passion for quality sound reproduction that drives Pioneer's industry-leading line of professional DJ headphones powers the engineering behind the dance-culture-inspired STEEZ Effects headphones. At the heart of the STEEZ Effects headphone is a pair of oversized 40 mm drivers which can handle up to an astounding 1,000 mW of input power, extremely efficient at translating all of that energy into loud, accurate sound with a 104 dB sensitivity.
Listen long, listen anywhere
Just like in the club, music is meant to be enjoyed over long periods of time. The STEEZ Effects headphones feature a lightweight frame and leather ear pads for ultimate comfort. A compact, folding design and carrying pouch make sure your lifestyle never has to miss a beat.
Focus on what matters
All of this unbridled power and passion is wrapped in an on-ear closed monitor design that provides passive sound isolation. Another coveted feature of the pros--this closed, sound isolating design minimizes sound leak from the external environment ensuring that nothing gets between you and your music.
In-line microphone with answer / end buttons
STEEZ Effects headphones come with a cord featuring an Apple-certified in-line microphone with call answer and music playback features. So you can use these headphones with your smartphone, iPod, iPhone, or iPad.

STEEZ Effects headphones are available in four colors: Red, Black, Brown, and White. Pick the Effects headphone that matches your personal style.

1 out of 5 eggsYuck!

Pros: None.

Cons: I thought I could trust Pioneer, but these headphones are aweful! The high notes are very cheap sounding and the bass sounds like someone turned the bass knob all the way up. They are also very flimsy. No matter how cheap the price, don't buy them! Yuck!
