It's always a good idea to use the very best plug adapters 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-adapter 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 adapter accessory for alleviating potentially damaging strain off the small sensitive mini-plug [3.5mm] source jacks on your smartphone, tablet, laptop computer, or portable headphone amp when using big headphones with stereo 1/4 inch full-size terminations. Gold-plated right-angled 3.5mm (1/8") male termination. This is the best adapter 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!
