Headset Market

       There are generally three major brands available for headsets in the current US

market; Logitech, Microsoft, and Plantronics. According to the information listed on the Best

Buy and CNET websites, the leading supplier in the market is Logitech, followed by

Platronics and Microsoft. Among these three brands, we have selected one representative

product from each brand in a similar price range and with desired features (please see Table

1), and conducted the following evaluation to make the best recommendation.

           Logitech: Logitech Premium Notebook Headset

           Microsoft: LifeChat LX-3000

           Plantronics: GameCom 377 Over-the-Head Stereo Headset

   Headset Critical to Quality Features

          The headset will be used for online verbal discussion during virtual classes. As part of

   the verbal human interface, the headset should have the following features, which indicate the

   critical to quality (CTQ) aspects for the Math TLC project:
                                                                       Headset Review 3


1. Quality of Sound Input: quality of sound captured by the microphone is measured as

   microphone response bandwidth.

       a. Microphone Response bandwidth – A wider bandwidth indicates a higher

          quality of sound being broadcast.

2. Quality of Sound Output: quality of sound output from speaker is dependent on

   noise cancelling and headphone response bandwidth.

       a. Noise canceling – Reducing unwanted ambient sounds by means of active

          noise control.

       b. Response bandwidth – A wider bandwidth indicates a higher quality of sound

          received.

3. Connection Type: USB versus regular jack connection and impact on teacher

   participant ease of use with synchronous conferencing package.

       a. USB is familiar, but may require changing the audio setup when using the

          synchronous conferencing package.

       b. Regular jack connection can be less convenient, but is default for audio on

          some synchronous conferencing packages.

4. Comfort of the Headset: the headset is designed to be comfortable for up to three

   hours of continual use in online courses.

       a. Ear-Cup Model: Over-the-head design is uncomfortable, placing enough

          pressure on the head to cause headaches over an extended period of time

          (based on personal experience of some Technology Team members).

       b. Behind-the-Neck Model: more comfortable then Ear-Cup model (based on

          personal experience of some Technology Team members).

5. Compatibility Issues: must be compatible with both Mac and PC Platforms.
                                                                                Headset Review 4


       The evaluation is based on the above CTQ features. In order to achieve this, we

established the following matrix to review and compare these features in a quantitative

manner.



Evaluation Matrix

       The three headsets were rated with respect to CTQ features and market share, the later

providing evidence of product quality. Each feature was ranked with scores ranging from 0

for weak fit, 1 for moderate fit, and 2 for strong fit to desired CTQs (See Table 2).

Purchase Recommendation

      After a thorough evaluation of the available headsets, the Technology Team

recommends the Logitech Premium Notebook Headset (Model: PN 980445-0403) for the

Math TLC project. The Logitech headset ranked highest on the Critical to Quality features,

and the high market share on headsets held by Logitech indicates the product is of high

quality. The average users’ ratings, the CNET editor’s review from CNET.com, and the

ratings from Logitech.com all rated the Logitech product as 3.5 stars (out of five), also

indicating the high quality of this product. CNET average ratings are not available for the

Microsoft: LifeChat LX-3000 and Plantronics: GameCom 377 headsets. However, Best Buy

rates the Microsoft: LifeChat LX-3000 at 2.9 stars (out of five) and both the Plantronics:

GameCom 377 and the Logitech product at 3.9 stars.



Summary of Product – Logitech Premium Notebook Headset

       First, the Logitech Premium Notebook Headset (Model: PN 980445-0403) has “noise

canceling” which reduces feedback and echoing, allowing clear communication between

faculty and teacher participants.

       Second, the product is designed for comfort, which is necessary when continuously

using the headset for several hours during online class sessions. Specifically, the behind the

neck design reduces physical contact to the head, reducing pressure that may lead to

headaches.

       Third, providing a USB and standard jack adaptors is convenient for teacher

participants, as they can choose either for use with the synchronous conferencing software.

While USB may be more familiar to some users, it can require reconfiguration of the audio

settings for the synchronous conferencing software. Having the option of using a standard

jack that does not require changing audio settings may be less confusing to some users. Of
                                                                            Headset Review 6


course providing training on using the audio wizard in the synchronous conferencing package

would reduce the USB concern.

Manufacturer/Company Background – Logitech

         The recognition of “Logitech” as a leading company in manufacturing computer

accessory products (for example, headsets and webcams) supports purchasing this product.

Logitech first became famous as a supplier of computer mice and then grew as the leading

company for interface peripherals of any kind. Logitech headsets are competitively priced,

high quality, and the designs are quite sophisticated. Their designs have earned many awards,

such as Design and Engineering Showcase Honors, Good Design, and an iF product Design

Award, not only due to aesthetics, but also because the design always considers the user’s

environment. Logitech is globalized, with products used everywhere in the world. They are

one of the biggest shareholders in the market.

Budget

         The Math TLC project has provided a budget of $50.00 for each student’s headset.

Although the Logitech Premium Notebook Headset price is $59.99, bulk purchase by the

Math TLC project will result in a discount on this price.
