Pioneer Expands Headphones Offering



Pioneer Electronics went heavy on the headphones in April, launching a multitude of models. The new products included a model that lets users adjust bass on the fly.

The Steez line of headphones is said to be inspired by the DJ and dance scene. Three models make up the line: 808 (SE-MJ7511), Effects (SEMJ7211) and Dubstep (SE-D10MT).

The 808 model features two sets of drivers: 40mm and 30mm. The ear cups have a dial that users can turn to minimize and maximize the amount of bass they want. Other features include plush ear pads, in-line Made for iPhone mic and controls, and a detachable cord.

Frequency range is listed at 8Hz to 28kHz, with a sensitivity of 104 dB and impedance of 16 ohms.

They will be available in May for a $129 suggested retail.

The Effects headphones ($69.99, May) come in four colors (black, white, red and brown) and have 40mm drivers and in-line mics. Frequency range is listed at 6Hz to 28kHz, with a sensitivity of 104 dB and impedance of 32 ohms.

The Dubstep headphones ($99.99, currently available) feature a DJ-style design with swiveling ear cups. Black or white versions are offered, both of which have swappable ear pads. The black model comes with green and orange ear pads, while the white model has blue and pink.

They too have 40mm drivers and the in-line mic and controls. Frequency range is listed at 8Hz to 28kHz, with a sensitivity of 105 dB and impedance of 32 ohms.

Separately announced were two highend models, the flagship SE-MJ591 and the noise-canceling SE-NC21M.

The SE-MJ591 ($299, April) features 40mm drivers, a foldable on-ear design with aluminum-alloy components and memory foam ear pads, and a detachable cord. A hard carrying case is included. Frequency response is listed at 5Hz to 40kHz, with a sensitivity of 108 dB and impedance of 32 ohms.

Model SE-NC21M (May, $119) uses a AAA battery to provide active noise cancellation. Battery life is said to be 120 hours, and the headphones will continue to operate when it dies.

Features include 30mm drivers, a foldable design, and an included carrying case. Frequency range is listed at 10Hz to 22kHz, with a sensitivity of 92 dB and impedance of 145 ohms when the active noise-canceling technology is turned on. When it’s turned off, sensitivity is 95 dB and impedance is 44 ohms.

Finally, Pioneer took the wraps off a pair of DJ-style headphones earlier this month that are geared toward the pro market.

The over-ear HDJ-1500 (May, $209) feature 50mm drivers and copper-clad aluminum wire voice coils, a frequency range of 5Hz to 30kHz, impedance of 32 ohms, and a maximum input of 3,500mW.

The leather-covered ear pads are made of urethane memory-foam, and they can swapped with Pioneer’s HDJEP01 open-cup protein leather ear pads that sit around the ears. Both the left and the right cups can swivel 45 degrees or flipped around 180 degrees for one-ear listening.

The headband and hinges are made of magnesium alloy, and the coil cord can be removed and replaced if necessary.

Two color options are offered: Deep Silver and Black Chrome. A carrying pouch is included.
