Our take on the JVC SU-DH1

by Ralph Graves

Put on your headphones and enjoy your DVDs, video games and music with spacious, virtual surround sound. The compact SU-DH1 surround sound headphone adapter from JVC makes it possible. The SU-DH1 works with just about any headphones. And it features an attached cable that plugs into the headphone jack of your laptop, handheld game, MP3 player or other device.

For home audio/video systems, the adapter features a mini optical digital input. With a mini-Toslink cable (available separately), you can run a digital feed from your DVD player or receiver for even more realistic effects.

The SU-DH1 makes a great travel accessory, too. An included adapter plug for airline systems lets you enjoy surround sound with your in-flight movies. The SU-DH1 provides up to 10 hours of continuous operation from two "AA" batteries — a real plus for longer international flights.

Line Attenuation Switch (LINE IN ATT): This switch allows you to adjust the input volume level of the component connected by line in cord. Set the switch to -8db in standard use.
