JVC is not exactly a newcomer to the world of noise-cancelling headphones, but most of its previous cans were aimed at the budget end of the market.
With the HA-NC250, costing around £70, the company is looking to take on the likes of the Bose QuietComfort range, but have these 'phones got what it takes to play with the big boys?
The first thing you notice when you put on these 'phones is just how comfortable they are. The ear cups are covered with a soft leatherette type material and are oblong in shape so they fit snugly on your ears. There's also not too much tension from the headband so you don't feel like you've got your lugholes trapped in a vice.
When not in use, the cans can be folded flat and stored away in the hard case that JVC supplies in the box. As most people will make use of these 'phones while travelling, JVC has also included a dual plug adaptor, so you can connect them to the headphone sockets commonly found on planes. There's also a 1/4-inch adaptor plug for use with hi-fi's that have larger-sized headphone sockets.
The noise cancellation circuitry is powered by a single AAA battery hidden in the right hand ear piece and controlled by a simple on/off switch. A single battery will power the 'phones for around 50 hours of noise-cancelling time, which is not too shabby.
However, JVC has really taken a twin approach to noise cancellation on these cans. The headphones are built using a double housing construction, which helps to insulate them from background sounds, even with the noise cancellation circuitry switched off. It certainly works well, but when you flick the switch to the 'on' setting, things get even better. They tend to work most effectively on background low frequency rumble and the air conditioning type noises you get on airplanes and trains than they do on cutting out people talking in the background, but they're still very impressive.
