Marketing Definition and Requirements 

This section shall contain consolidation of the process in product marketing. It is 
acceptable that spec can be a bit loose in this chapter but subsequent chapters leave no 
room for loose specs. 

1.1

 

General Description 

The product is a Bluetooth-enabled USB audio device intended to be used as an accessory 
for standard industry PCs. It is designed to work with BT headsets as long as they adhere to 
the Bluetooth 1.2 specification supporting the headset Bluetooth profile and supports no 
other BT function than bi-directional audio streaming (no support for other BT devices like 
Keyboards, Mice, DFU etc.)

 

 
The product targets primarily the ingenuous consumer or first-time headset user who 
appreciates a hassle free truly PnP solution which operates instantly without requiring 
neither configuration nor any installation of software, driver etc.   

1.1.1

 

Market Problem 

Due to an increasing interest in convenient VoIP services on standard industry PCs, where 
headsets are a prerequisite, there is a growing demand for inexpensive, easy to install and 
easy to use cordless headsets solutions. 

1.1.2

 

Product Problem 

Originally BT headset intended to be used with Mobile phones supporting voice services 
only. Existing BT implementations on PCs consist of built-in BT components or external 
accessories, like USB dongles, with BT functions and additional BT SW. This PC BT 
implementation compared to built-in BT in telephone handsets is much more complex 
(normally supporting many more profiles), and more focused on data use instead of voice 
services, even if those solutions are capable supporting, e.g. headset or handsfree profile. 

1.1.3

 

Technology Problem 

For BT support in a PC environment a BT Host protocol stack/SW needs to be operated on 
the PC. This software needs to be installed, managed and launched by the user on the PC 
before the headset can be paired and used for e.g. VoIP services. This kind of use is much 
more complex and challenging for the user compared to the BT telephone 
implementation/use case.

Key Features, Benefits and USPs 

This section is informative. This is a list of new, essential and unique features which 
differentiates the product. 

Feature 

Benefit, explanation, comment 

Mono and Stereo capabilities on 
same hardware platform 

Core unit performs as a mono / voice solution .   
Firmware is user upgradeable to additional 
stereo operation. In this state the product 
converts into a mono/voice plus stereo 
streaming device depending on BT HS 
capabilities (=Swan). 

Ease of use 

A330 (and Swan) is a truly PnP solution not 
requiring any specific driver or installation of 
dedicated software for basic operation. Even 
though A330 is state of the art in terms of MS 
Windows operating system (XP or higher) 
support with MS standard USB and audio 
drivers.
