Connecting to an audio source

Connecting to an audio source

You can use the headphones with a variety of audio sources: airline audio, a CD, DVD or MP3 player, a per- sonal or laptop computer, or home stereo. The maximum input voltage is 9 Vrms.

To make the connection, insert the headphone plug into the jack on the audio source you will use.

Notice the jack conﬁgurations on the left in the chart below. Instructions on the right tell you how to connect to each type of jack:

A single, 3.5 mm jack (on most portable

sources) – use the single plug. No adapter needed.

Two 3.5 mm jacks – use the dual plug adapter.

One 3.5 mm jack and one power jack – use the single plug in the 3.5 mm jack (the larger one). The smaller jack does not need a connection.

One power jack and two 3.5 mm jacks – use the dual plug adapter for the two 3.5 mm

jacks. The power jack does not need a connection.

One 6.3 mm jack (for home stereos) – use the 6.3 mm stereo phone adapter.

Note: Audio jack conﬁgurations on airplanes vary. Also, airline audio may not equal the high quality audio you can get from a home stereo or a portable source.

QC-2 specifications

The Bose QuietComfort 2 (QC-2) headphones were introduced as a benchmark in the realm of noise-canceling audio technology. These headphones quickly became synonymous with comfortable listening experiences, deployed particularly by frequent travelers and urban commuters who sought a respite from environmental noise.

One of the standout features of the QC-2 is its advanced Active Noise Cancellation (ANC) technology. This system employs microphones both inside and outside the ear cups to detect and analyze ambient sounds, effectively producing opposing sound waves that cancel out unwanted noise. This acoustic innovation ensures that users can dive deep into their music or podcasts without the distractions of the outside world.

Additionally, the QC-2 headphones feature plush ear cushions that are designed for long-term wear, providing both comfort and passive noise isolation. The lightweight design further enhances the listening experience by allowing users to enjoy extended periods of use without discomfort. The headband is adjustable and crafted from soft materials, ensuring a snug yet gentle fit.

Another notable characteristic of the QC-2 is its audio performance. Bose has a longstanding reputation for delivering high-fidelity sound quality, and the QC-2 is no exception. Users experience deep bass, balanced mids, and crisp highs, enhancing the audio experience across genres. This is complemented by the headphones' ability to provide consistent sound quality regardless of ambient noise levels, guaranteeing an immersive experience whether in a quiet room or bustling subway.

Battery life is an area where the QC-2 shines. With an impressive playback time on a single charge, these headphones can keep up with the demands of long trips and busy schedules. Moreover, the simple controls allow for easy management of volume, play/pause functions, and calls, providing user-friendly accessibility that doesn’t distract from the listening experience.

Finally, versatility is a key feature of the QC-2. While designed primarily for personal audio enjoyment, they are compatible with various devices, including smartphones, tablets, and laptops, thanks to standard audio jacks and Bluetooth connectivity options. This adaptability ensures that users can seamlessly integrate the QC-2 into their daily lives, making it an ideal choice for anyone seeking high-quality audio combined with cutting-edge noise-canceling technology.
