But, could the scarcity of this limited item have stoked desire from online headphone communities Once a Massdrop closes, chances are that product may never be seen again. Massdrop Drops Fostex TH X0. Purpleheart and Ebony. Great news Not only did the TH X0. Fostex upped its Massdrop game by bringing back the TH X0. Mahogany, but two new wood grains Purpleheart and Ebony. Fans that missed out on Mahogany now had a lot to consider Fostex promised that as you went up the line from Mahogany to Purpleheart to Ebony, the wood grain increased in density, resulting in a unique sonic signature namely, a less resonant and more subtle bass response.

According to Fostex and the TH X0. Lets take a closer look at the TH X0. Purpleheart.  Look and Build Quality. The first thing headphone aficionados will notice when cracking open their new Fostex TH X0. In our post Steve Jobs era, lavish packaging and unboxing has become a kind of expectation one that in my humble opinion is way past its sell by date. So, its actually a refreshing surprise to find these relatively high end headphones packaged in what looks like a recycled pizza box, then taped up in bubble wrap like a mail order car part. As soon as you tear off the bubble wrap, the gleam of polished purpleheart earcups will dazzle your eyes like pure gold. Youll quickly forget being cheated out of a fancy unboxing ceremony, and you may appreciate that the cost saving measure resulted in more headphone for less money. But upon closer inspection, and for better or worse, Fostexs corner cutting extends beyond the packaging. The TH X0. 0 earcups are solid and balanced like a fine musical instrument. From Fostexs own biodynamic drivers to the faux leather earpads that envelop your head like a lovers embrace the parts that make contact with your ears are quality. But the earcups themselves dont have much swivel and certainly wont bend to lie flat for portable storage. The headband and adjustment mechanism are decidedly less than high end, made from cost cutting plastic, and they lack the solid build quality of the earcups. So, while the earcups make the Purpleheart look like a 1. Which really isnt terrible. If anything its probably the best place to cut cost. But another cost cutting measure Fostex employed across the TH X0. This is non ideal for users whose headphones have to endure the abuse of teenagers borrowing their headphones or audiophiles that like to tweak their cables to improve sound quality. The cable Fostex used on the TH X0. On one hand, not many headphones include such a long, thick, well made cable. I have no doubt that if youre into cables, this should satisfy the need for audiophile grade. Photo Booth App. But the downside to the high quality cable Fostex chose is its not removable So, basically youre stuck with a 1. Y cable attached to your headphones that is practically as thick as a fire hose. The heavy fabric around the cable is designed to resist entanglement but also resists being bent or wound up to fit into a pocket sized space for on the go listening. At the end of the cable is an audiophile grade quarter inch plug, but Fostex also includes a 3. The headphones do come with a soft leatherette bag with a drawstring to help protect them on the road. But its too bad the TH X0. Theyre just so darned beautiful, youll find yourself wanting to conspicuously wear them in public. TH X0. Headphone Setup. The TH X0. Purpleheart headphones only have a very light 2. This means they will work off your cell phone, but for dedicated listening youll be better off with some kind of external headphone amplifier. I tested these headphones under two conditions For home listening, I used a combination of Emotiva DC 1. DAC connected to a Cavalli Liquid Carbon series 2 headphone amp. This headphone rig has sounded spectacular with any headphones Ive connected to it, and they drove the TH X0. At work I sit in front of a laptop using. Optoma Nu. Force u. DAC5 a perfect companion for the workday.
