Beyerdynamic is better known for making high-end and pro monitor headphones. Lately, however, it's been rolling out affordable models, including the DTX 350 p, that are aimed at a mainstream audience.
Available in black or white, the DTX 350 p, which retails for about $70 online (£35 UK and can be found online in Australia for around AU$125), is designed in Germany but made in China, and cosmetically speaking, it's pretty ho-hum with a mostly plastic construction. On the plus side, for a lightweight 4.6-ounce headphone, it does seem reasonably sturdy and more importantly, is comfortable for an on-ear model with nice, soft leatherette earpads. It offers a snug fit with decent noise isolation -- it leaks a little sound at higher volumes -- but doesn't clamp down on your ears too firmly.
A small, rectangular pouch is included, and with a little effort, the headphones fold up to fit inside it (the pouch looks like something you'd store sunglasses in, not headphones).
