Authentic performance inspired by decades of experience as the #1 professional DJ brand.

For over 15 years, Pioneer has been engineering award-winning products trusted by the World’s most respected professional DJs and musicians. With a portfolio of industry firsts including the World’s first scratch CD player and scratch DVD player, Pioneer has been transcending the limits of how enthusiasts emotionally connect with their music through innovative technology, performance and design. Pioneer's range of DJ-inspired headphones distills the essence of their professional products into a compact, stylish and consumer-friendly package available to all music lovers.

Pioneer’s professionally-inspired sound tuning heightens the presentation and impact of both high and low musical notes. Similarly implemented in Pioneer’s professional headphone line, this unique tuning philosophy is favored by pro DJs in order to make it easier to time and mix music tracks. Characterized by crystal clear highs, and deep pounding lows, the Bass Head DJ-inspired headphones get you closer to your music and the club scene with an energetic listening experience reminiscent of their award-winning pro models.


  • newegg Relentless Performance The same passion for quality sound reproduction that drives Pioneer's industry-leading line of professional DJ headphones powers the engineering behind their DJ-inspired consumer models. At the heart of the Bass Head headphone is a pair of 9 mm drivers which can handle up to 100 mW of input power, extremely efficient at translating all of that energy into loud, accurate sound due to its 110 dB sensitivity rating.
  • newegg Maximum comfort and durability A high quality OFC Litz cord provides a potent connection to your portable audio/mp3 player. The included 4 different sizes of ear tips ensure a custom and comfortable fit during extended listening period.

5 out of 5 eggsGreat headphones for working out

Pros: - very good sound reproduction for in-ear headphones, good bass and fine treble, exactly what I expected from 5 Hz - 22 kHz specification.

- with a few different size sets of rubber ear buds, they're as good as noise-canceling ones.

- durable, the cord's insulation is thicker than most in-ear headphones I used in the past; despite being folded, bent, tangled and untangled infinite amount of times, there is no loss of signal in any left or right channel, which I attribute to the physical properties of thick, excellent wear-resistant insulation. the same can be said about the connector - everything works perfectly like on the day I got them.
the wires are stiff for a reason - they're supposed to withstand physical abuse for months or even years. it's a pro, not a con.

- withstand occasional and accidental yanking out of whatever they are connected to (due to shorter than expected cord length) without any breaking or tearing,

- the red/black cord style factor - they look way above average, are very distinctive from afar in a room of people where everyone else is wearing white in-ear headphones (you can guess the brand). so if 99% of people in the same room "think different", and you're the one actually thinking different, how cool is that?

Cons: - 1.2 meter length is a bit too short, it could use 1.8 meter at least. that's about the only con i can think of.

Other Thoughts: totally worth the price.

running for prolonged time is totally possible with these (just match the ear bud size that's right for your ears). they don't fall out.

if you expect the audio quality of full-size headphones, you're looking at the wrong item. they are to be used outdoors, not for audiophile sessions at home.

of all the reviews here, only 1 other buyer has used them for more than a year, and gave it 5 eggs.

aside from defective units that may have caused other reviewers to give these headphones low rating, I think you can hardly find better quality, better sounding or more comfortable to wear outside in-ear headphones. and they'll make you look cool too (the red/black cables).

4 out of 5 eggsAre my ears shaped weird?

Pros: Excellent sound for $20 earbuds. Don't expect them to blow your mind, but they certainly beat iPhone buds any day. They're bassy, but not overwhelmingly.

Bass - 5/5
Mid - 4/5
High - 3.5/5

Cons: I've never had earbuds fall out of my ears like these do. They feel very comfortable, but if I'm moving around at all, they'll fall out every 10 minutes. Running is pretty near impossible for me with these.

Could just be my ears, but take it for what it's worth.

Other Thoughts: Definitely still a "Buy". Some of the best sounding earbuds you'll find for a reasonable price.

2 out of 5 eggsJust OK

Pros: Easy to tell left/right if you need to know, I guess.

Cons: They do not sound like what you would expect from Pioneer. I was disappointed. Side by side, the $20 Skull Candy ear buds I have sound 100x better..clearer. These seem muffled, dull sounding. I've been a professional radio DJ for 20+ years, I know headphones. Buy another brand.

5 out of 5 eggsIncredible Sound

Pros: Really really good sound and bass. Ive been looking for a good set of headphones like these for a long time. Insulation on the wires are a good quality, and not cheap. These are just awesome, but then again they are made by pioneer.

Cons: Would be nice if they had a built in mic for use with cell phones. Little pricy at $50. Im always afraid to spend that kind of money on something when I don't know how good it is. I got these when they were on sale on the E-Blast for $20. But If and when I break these I wouldn't flinch at paying 50 to get another pair.

Other Thoughts: When I would use my $100 bluetooth headphones to cut the grass with I would have a hard time hearing the music. Now I can barely hear the lawn mower and I'm turning the volume down because the music is so loud. Comes with different size rubber pieces for people with smaller or larger ear canals.

5 out of 5 eggsvery good headphones

Pros: Very good sound quality for a reasonable price (got them on sale 20 bucks bought 2 =) The ear buds have removable inserts that range from small to large to ensure best audio quality. COMFORT!!! I have never owned ear buds that were this comfortable before in life. Overall if you can get them for 25 or less its a steal

Cons: I did have 1 break on my after about 7 months of pretty hard usage. But as compared to beats headphones I had a back up and those 2 where still wayyy cheaper then 1 beats.

Other Thoughts: If your on the fence with these be like nike and "Just do it"
