Excellent full-size 1/4" to 1/8" mini-plug adaptor with a right-angled 3.5mm male termination. Takes potentially damaging strain off highly susceptible 'mini' 1/8" iPod, iPad, iPhone and laptop headphone jacks when using larger headphones with big 1/4" stereo plugs. Unbreakable plastic 1/4" housing minimizes weight. Highly recommended, hard-to-find Cardas / HeadRoom adaptor delivering superb ergonomics, durability and sound quality.

Product Features:

  • Reference-grade 1/4" to 1/8" flexible adaptor exclusive to HeadRoom
  • Ideal accessory for full-size 1/4" plug headphones + iPad, iPhone iPod or portable amps
  • Employs proprietary Cardas high-definition HPI 'Mini' interconnect cabling
  • Excellent gold-plated 3.5mm right-angled male jack
  • Unbreakable plastic 1/4" female housing minimizes weight

What's In The Box:

  • 1 - Cardas 1/4" to 1/8" headphone plug adaptor accessory

It's always a good idea to use the very best plug adaptors possible in your headphone system. Rest assured that's precisely what you'll get with every one of Oregon-based Cardas Audio headphone cabling and headphone connector products.

This short 6-inch length (approx) of highly pliable flex-adaptor uses the renown Cardas Audio 'mini' HPI interconnect cable design/construction wedded to a beefy female 1/4" full-size connector via an extremely strong heat-shrunk relief joint. The female 1/4" receptacle is built of a very durable lightweight plastic to minimize the housing weight. It's the perfect adaptor accessory for alleviating potentially damaging strain off the small sensitive mini-plug [3.5mm] source jacks on your iPod, laptop computer, or portable headphone amp when using big headphones with stereo 1/4" full-size terminations. Gold-plated right-angled 3.5mm (1/8") male termination. This is the best adaptor of this type that we've ever tried here at HeadRoom and a rather hard to find but critical accessory -- so get an extra one for your other set of reference headphones!

Excellent sound quality compared to Radio Shack adaptor
Posted by jtrimm from Philadelphia suburbs, PA on 2012-10-23

Recommend Product: Yes
Pros: Works well with DragonFly
Cons: None so far...

I have a set of Sennheiser HD600's with the old blue Cardas upgrade cables with 1/4" plug (has it been 10+ years with these cans already?). I recently purchased an AudioQuest DragonFly which only takes an 1/8" headphone plug. I started with an Radio Shack adaptor. One of the problems is the weight/stiffness hanging off this small USB DAC/amp. The Cardas adaptor, with the 90 degree plug and short cable, puts less physical stress on the DragonFly. Sound quality is also excellent and a marked improvement compared to the Radio Shack adaptor (even right out of the box). I treated both the Radio Shack and Cardas headphone adaptor with Deoxit and Deoxit gold.

Recommend Product: Yes
Pros: Right angle 1/8 plug plus more
Cons: None

Well worth the money! Just what I needed: A well made right angle 1/8 plug, connected to a ¼ end by several inches of flexible cable (to help keep movement of the ¼ end from having any effect on the 1/8 end). I used to have a Radio Shack adaptor sticking out of the side of my Total Bithead. Probably not the greatest quality to start with, but even if it was, to have an adaptor sticking straight out (vs right angle) always seemed like a dumb idea to me, but that’s all I could get. The body of the ¼ inch plug coupled with the body of the adaptor added up to a solid piece close to 3 inches long sticking straight out and only being supported/stabilized by its 1/8 inch pin. That’s a lot of leverage on that little plug. The slightest movement and a channel would go out. You always had to jiggle the plug, etc. Drove me nuts. The Cardas adaptor appears to be very high quality. I’m happy. I loaded music onto my smart phone, then run it through a Total Bithead to power an old set of Sennheiser HD 580 phones. All things considered, the sound is pretty amazing.

Senheisser HD 650, Headroom Ultra Micro Amp, Cardas adaptor
Posted by Sound Ideas from Montreal, Quebec on 2010-01-18

Recommend Product: Yes
Pros: Excellent- wonderful musical synergy between cables, amp and headphones
Cons: none

This review is for the three above mentioned products I have purchased from HeadRoom in the last 3 months and the fine synergy between them, and not just the Cardas adaptor: After spending more than 20 years in the A. V. business one begins to realize that who you buy from is nearly as important as the product itself.The nature of music descriptions are quite limited and full of cliche simply because words and sound do not mix easily.In some cases the equipment reviewers sometimes just furnish us with the words we want to hear and can identify with. In many ways describing music is like trying to describe a fine wine or a wonderful painting.Of course,it should be a personal experience, but all personal experiences are shaped by many outside influences. This leads me to the importance of good personal advice in sound. This means that people who are credible and who are interested in your choice of music and the way best to express it given the factors involved[ including making a price and suggesting the appropriate product] must take the time to listen and, in short,care. We all know that we can buy products at other places and perhaps at a slightly discounted price, but I can assure you I have never experienced purchasing any product on the web that came with such professional and personal recommendation as it does at HeadRoom. And, the price was also very competitive. Sound is difficult to buy when you cannot hear, but you can trust these people at HeadRoom to hear for you.
