So, what do you get?
The Bluetooth SIG (Special Interest Group), released Bluetooth 4.1 as an incremental software update to Bluetooth 4.0 on 4 December 2013. This update incorporated the Bluetooth Core Specification Addenda (CSA 1, 2, 3 & 4) in this, new features were added that improve consumer usability. Including increased co-existence support for LTE and bulk data exchange rates.
Whether you’re at home or out and about, background sounds such as ambient noise, road noise and other people talking can make having a clear-sounding conversation difficult. Qualcomm® cVc™ noise cancellation technology brings advanced audio enhancements and noise suppression to the near and far end, and provides packet loss and bit error concealment. In combination, this delivers the best possible call quality on Bluetooth headsets, handsets, hands-free devices and automotive communication devices. (Qualcomm®)
What are they like to use?
Now to the Quality of the Sound.
As always, i put these through their paces. I used a Benchmark test and some of my favourite listening tracks. Let’s see how they performed.
Please Note:- I am 57 and peoples hearing change as they get older, so this is just the results that i found with my delicate ears. The Headphones were tested with flat equalisation. Tests performed using 24-bit/96kHz FLAC Files on a FiiO X3 2nd edition.
Frequency response stated:- 20Hz – 20kHz. I found heard frequencies of 20Hz – 13kHz
Spectral Flatness:- Did the Headphones perform with equal volume across a full Spectral frequency sweep. The tone stayed central across the whole frequency spectrum.
Dynamic Range:- 72 dBFS (decibels below full scale).
Quality Test:- (Bass Shaker) The sweeping tone sounded pure and clear throughout all frequencies. There was no parasitic buzzing or rattling sometimes found in budget products.
Driver Matching:- (All frequencies swept from 10 Hz up to 10 kHz. at exactly the same sound levels in both earphones) The tone stayed in the central position throughout the frequencies.
Correctly wired:- (left plays on left and right on right) Perfect.
Polarity Preserved:- (wired in phase) They are wired in Phase.
Binaural Test:- (a knock to a wooden door, first right then left) The Knocks very clear and lifelike.
Last but not least, listening to my favourite music. How does it sound? (Tracks used for this were as follows)
Izzy Bizu – Talking to you. Adele – Hello. Michael Jackson – She’s out of my life. 10cc – I’m not in love. Michael Jackson – Don’t stop ’til you get enough. A-ha -Hunting high and low.
