When a company refreshes a product range and simply puts a lower-case letter at the end of the product title, you know you're in for a minor update. This is the case with the latest high-end stereo Bluetooth headphones from Nokia, the BH-905i. They look identical to the headphones that preceded them, with the few updated features existing below the surface.
In style, design and physical dimensions, the BH 905i is a dead ringer for the former model. Nokia has managed to shave 8g off the unit's weight and slim down its profile when folded flat, but otherwise you'll have great difficulty telling them apart. The sales package remains equally generous, with a huge range of cables and adapters covering all possible use cases for these headphones, including an aeroplane adapter and a dedicated iPhone cable.
The fit of the BH-905i is comfortable to begin with, but we found that over the space of about an hour the heat of the pleather ear-cups, along with the gentle pressure of the headband, build up to produce a slightly unpleasant experience. If you're considering the BH-905i to drown out engine roar on a long-haul flight you'll want a chance to test these for yourself first to see if you find them more comfortable than we did.
One of the key selling points for these headphones is active noise cancellation, delivered with the help of eight microphones and activated by a switch on the underside of the left-hand side speaker. This feature works impressively well; the almost imperceptible white noise blocks outside noise so well that you'll feel like you're in a sensory deprivation tank even when you're on the bus or train.
