== Comparison Article ==
The user wants a 500-word Wikipedia-style article comparing the Bose QuietComfort 15 (QC15) and QuietComfort 3 (QC3) headphones.

I need to follow a strict set of guidelines to avoid AI writing patterns. This means focusing on a neutral, encyclopedic tone, using simple wikitext, and avoiding things like promotional language, editorializing, overuse of conjunctions, section summaries, etc.

The article structure is clearly defined:
1. An opening paragraph with citations.
2. A wikitext comparison table with 4-10 rows.
3. Additional sections if needed.
4. A reference list (which will be auto-generated based on my inline citations).

My process will be:
1. **Analyze Search Results:** I have a good set of search results that directly compare the QC3 and QC15.
2. **Extract Key Differences:** I'll pull out the main points of comparison. Based on the search results, these are:
* **Design/Fit:** Over-ear (Circumaural) for QC15 vs. On-ear (Supra-Aural) for QC3.<ref name="ref1" /><ref name="ref2" />
* **Power Source:** AAA battery for QC15 vs. Rechargeable lithium-ion for QC3.<ref name="ref1" /><ref name="ref2" />
* **Battery Life:** ~35 hours for QC15 vs. ~25 hours for QC3.<ref name="ref1" /><ref name="ref2" />
* **Noise Cancellation:** QC15 is noted as being slightly more effective.<ref name="ref1" /><ref name="ref3" />
* **Sound Quality:** QC3 is often cited as having better sound quality, especially at higher volumes, with the QC15 showing some distortion.<ref name="ref1" /><ref name="ref3" /><ref name="ref2" />
* **Portability/Size:** QC3 is smaller and more compact.<ref name="ref1" /><ref name="ref2" />
* **Passive Operation:** Neither headphone works for audio if the battery dies.<ref name="ref4" /> The noise cancellation must be on for the QC3 to work at all.<ref name="ref1" />
* **Cable:** Both have detachable cables, some with inline remotes for Apple devices.<ref name="ref1" /><ref name="ref5" />
* **Weight:** There are specific weights mentioned. QC3 at 4.8 oz or 5.6 oz and QC15 at 4.9 oz or 7.1 oz depending on the source. I'll use a consistent source or acknowledge the slight variance if needed.<ref name="ref1" /><ref name="ref5" />
3. **Write the Opening Paragraph:** I will introduce both models as part of Bose's noise-cancelling lineup, mentioning their respective release dates (QC3 in 2006, QC15 in 2009).<ref name="ref1" />
4. **Create the Comparison Table:** I will format the key differences into a `wikitable`.
5. **Write Additional Sections:** I'll add a couple of short sections to elaborate on the key areas of difference: `Design and Comfort`, `Performance`, and `Power`. This will allow me to incorporate more detail and citations naturally.
6. **Review against Guidelines:** This is the most critical step. I will meticulously check the generated text against the long list of "AI writing patterns" to ensure I have avoided them. I will check for:
* No undue emphasis on symbolism/importance.
* No promotional language ("breathtaking," "rich tapestry").
* No editorializing ("it's important to note").
* No superficial analyses ("highlighting," "underscoring").
* Varied conjunctions, no overuse of "Furthermore," "However."
* No "In conclusion" summaries.
* No "Challenges and Future Prospects" sections.
* No negative parallelisms ("Not only... but also...").
* No rule of three.
* No vague attributions ("some critics argue").
* No elegant variation.
* No false ranges.
* Use sentence case for headings.
* No excessive boldface.
* No inline-header vertical lists.
* No emojis.
* Use em-dashes sparingly, if at all.
* Use straight quotes.
* No letter-like writing.
* No collaborative communication ("Here is a...").
* No knowledge cut-off disclaimers.
* No placeholder text.
* Correct wikitext formatting for citations and the table.
7. **Format Citations:** I will use the `<ref>` tag format as requested for MediaWiki.
8. **Final Word Count Check:** Ensure the final output is around 500 words.

This structured approach should allow me to meet all the user's requirements and produce a high-quality, human-like article.== QC15 vs. QC3 ==
The Bose QuietComfort 15 (QC15) and QuietComfort 3 (QC3) are both wired, active noise-cancelling headphones produced by Bose Corporation. The QC3 headphones were released in 2006, followed by the QC15 model in 2009.<ref name="ref1" /> While both models were designed for travel and commuting, they differ significantly in their design, power source, and audio characteristics.<ref name="ref1" /><ref name="ref2" /> The primary distinction lies in their ear cup design, with the QC15 being an over-ear model and the QC3 an on-ear model.<ref name="ref1" />

=== Design and Comfort ===
The most noticeable difference between the two models is their physical design. The QuietComfort 15 features an around-the-ear, or circumaural, design where the earcups fully enclose the user's ears.<ref name="ref1" /> This creates a physical seal that contributes to passive noise isolation before the active noise cancellation is engaged.<ref name="ref2" /> In contrast, the QuietComfort 3 has an on-ear, or supra-aural, design, with smaller earcups that rest directly on the ears using memory foam pads.<ref name="ref3" /><ref name="ref2" />

The on-ear design of the QC3 makes it a more compact and portable headphone, with a smaller carrying case.<ref name="ref1" /><ref name="ref2" /> The over-ear design of the QC15 is larger but is often preferred for long-term wear, as the pressure is distributed around the ear rather than on it. Some users reported that the QC15's earcups could get warm over time, while the over-ear pressure of the QC15 was noted to create a more pronounced pressurized sensation for some listeners.<ref name="ref3" />

=== Performance ===
In terms of active noise cancellation, sources generally report the QC15 to have a slight performance advantage.<ref name="ref1" /> Its over-ear design and acoustic technologies provided more effective sound dampening, particularly in environments with varied frequencies like offices.<ref name="ref3" />

Regarding audio reproduction, the QC3 was often considered superior.<ref name="ref1" /> The QC3 provided better sound clarity and detail, especially at higher volumes.<ref name="ref1" /> The QC15, while delivering clear sound, was noted to suffer from some audio distortion when playing louder music.<ref name="ref3" />

=== Power ===
The two models used different power solutions. The QC15 was powered by a single AAA battery, which provided approximately 35 hours of use.<ref name="ref2" /> This allowed for a quick swap when power was depleted, a convenience for travelers.<ref name="ref2" /> The QC3 used a proprietary rechargeable lithium-ion battery that lasted about 25 hours per charge and required a separate charging unit.<ref name="ref2" /> Neither model could be used to listen to audio once its battery was depleted.<ref name="ref1" /><ref name="ref4" />
