The Good: Decent sound quality; nice build; carry pouch included. The Bad: Earcups are too small; noise cancellation not very effective; sound leaks out. The Bottom Line: For the price, the JVC HA-NC80s offer an acceptable sound quality, but the noise-cancelling feature just isn't up to what it could be. Anyone on a budget should give them a try, but if you can afford more money you can find much better performance JVC's HA-NC80s offer a truly affordable way for you to escape the hums and bangs of office chatter, public transport engines and aeroplane turbines. are designed to reduce the sound level before it even reaches your eardrum, and JVC claims the HA-NC80s will block 75 per cent of such ambient noise. For around \u00a340, that's an enticing claim. \r\nDesignThe HA-NC80s fold up into a convenient flat semi-circle shape for easy storage, making them extra-suitable as travelling headphones. The 1.5m cable feels rugged and hard-wearing. The top-most part of the headband is nicely padded and it extends enough to accommodate even the widest of skulls. \r\nThe earcups are very well padded, but incredibly small. Unless you have ears no larger than a two-pence piece, you'll struggle to get your whole ear inside. This sadly makes periods of extended use quite uncomfortable and we found ourselves having to give our ears a five-minute break every hour or so to give them a rest from the pressure. \r\nNoise-cancellation controls feature on the lower part of the right earcup and are easily accessible with a thumb. \r\nFeaturesLiving up to their name, the HA-NC80s' main feature is noise cancellation. Two modes are supported: 'Low' for countering noise you might experience on a bus, and 'Wide' for use on the Tube or on a plane. The headphones will last for up to 50 hours from a decent AAA battery. \r\nWe found that the 'phones manage to block various low-level frequency sounds -- such as our air-conditioning system in the office -- fairly effectively, but voices, keyboard tapping and coughing (it's flu season here at CNET.co.uk) were let through without hindrance. \r\nWe don't have as many jet engines hanging around our offices as British Airways might, so we can't vouch for the cancellation of in-flight noise. But our tests on the Tube certainly showed that the HA-NC80s leave a lot to be desired in the noise-cancelling department.
