A Splendid Listening Experience,
This review is from: Blackbox i10 ANR Active Noise Cancelling Earphone for iPod (Wireless Phone Accessory)
Customer review from the Amazon Vine Programme (What's this?)
The Blackbox i10 Active Noise Rejection (ANR) headphones by Phitek are probably an audiophiles dream.
I have been sampling and reviewing headphones of various type and price range, quality and build, for some time. This is an iPod specific product, complete with the well known 30 pin connector.
Phitek are experts in developing electro-acoustic technology products for the airline industry. Based in New Zealand they were formed to provide solutions to the air passenger listening experience - in particular, noise reduction.
Rich punchy bass and crystal clear treble. Tembre - the ability to distinguish different instruments in a busy mix of sound, is noticeable. Volume can reach much higher levels than many headphones, without any distortion.
I sampled using a range of audio including folk, country-rock, speech and pop.
The Noice Cancelling Technology:
Phitek own the trademark Active Noise Rejection(tm).
The ANR works by measuring noise and generating an "anti-noise" response. Anti-noise is an inverted copy of the noise itself (generated by one microphone in each earpiece and one in the medallion for monitor function). The Noise Cancellation is up to 22 decibel and passive isolation up to 35db.
But does it really cancel noise? Yes, and the best part is - no additional battery pack or power charger is required. The noise cancellation is stated at being up to 22db. This is pretty similar to the average level of a pair of foam earplugs.
I tested the headphones by taking a pencil and tapping it on a wooden surface near me (while playing country-rock, at medium to high volume). At first I can hear the tapping, but the sound miraculously begins to deaden as the microphones located on the earphones and volume control panel pick up and allow the cancellation to take place. Then I compared to a conventional pair of high quality in-ear `noise isolating' (not cancelling) phones, at same volume. While both pairs performed well, the difference was noticeable.
I tested in a similar way, by clicking my fingers, tuning a radio to create white noise and flicking a light switch. Interesting to note - if you place your finger tips on the headphone sockets while listening, you can hear the sound adjusting itself to the interference. Therefore proof that the product is alive and working well.
At under £100, less than the price of other well known Sound Isolating Headphones you get an excellent listening experience and a hard carry case for your iPod too. They feel well made, coated in black rubber/silicone, surely able to withstand day to day use, in and out of pockets and bags. Recommended.
