June 2, 2009 Experience sound and silence with the revolutionary Nokia Bluetooth Stereo Headset BH-905 with active noise cancellation Nokia today launched a headset ideal for listening to music and making calls with virtually any compatible phone or music device, with or without a wire. The Nokia Bluetooth Stereo Headset BH-905 with active noise cancellation combines two in one – both music and calls – and provides crystal clear sound by eliminating background noise with novel active noise cancellation technology from Wolfson Microelectronics, a leader in high performance audio technology. This multi-microphone feed-forward active noise cancellation technology allows for pure sound without ambient noise and is now introduced for the first time in the Nokia Bluetooth Stereo Headset BH-905.
These days I was awfully glad to hear about Q-Sound's new concept of a headphones: solar-powered Bluetooth Stereo headset. It uses absolutely free and renewable solar energy!
This is the first test of a speakerphone for this site. I tested Avantalk Pioneer with different devices, for example desktop computer with BlueSoleil, laptop, MP3 players, and among them, to complicate the task, was Palm Treo with Softick Audio Gateway installed.
As for iPod Nano 3G, I tried to test with it too, but naughty thing refused to work with Avantalk Pioneer. I can't say now whose fault is - adapter's (Satechi SRS-200BD Bluetooth Audio Dongle for iPod / iPhone ) or speaker's. AVRCP worked flawlessly, but no sound I heard, just some croaking from time to time.
Also I took a non-A2DP mobile phone for calls testing, to see how it works with older cellphones.
Appearance
Well, as I unpacked the speakerphone, I saw two joint speakers in a black and silver rectangular casing. The arrival turned out to be a very lightweight, not big, easy to be carried anywhere device. It has a stand that folds up when the speaker is temporary not in use, or if you are carrying the Pioneer from one room to another while listening. According to specs, its size is 206mm*88mm*42mm and weight is 295g without battery.
Recently we've tested a headset called Avantalk AS1. Let's see what we've learned.
Design
So, the headset is of behind-the-neck design with foldable headband (but this headband is not adjustable). It looks like a mix of two famous headsets: Jabra BT620andPlantronics Pulsar 590. If you like Plantronics' black-and-silver earpieces and Jabra's behind-the-neck design, Avantalk AS1will be just for you.
The CK-600 car kit is the new A2DP-enabled product manufactured by Nokia. The gadget sports adjustable and detachable 2.2 inch TFT display that gladdens the eye with 65,536 colours. The display shows caller ID and not only - it helps to put to rights the synchronized contacts, so you can make outgoing calls. The car kit allows to download for two users up to 3,000 phone numbers each, and can handle 2 calls at a time.
