Design and Build Quality: Bose QC Ultra Headphones vs. Bose NC 700

As we delve into the design and build quality of the Bose QC Ultra Headphones, it’s clear that Bose has made some notable changes, distinguishing them from their predecessor, the Bose NC 700. Let’s break down these aspects to understand how these changes impact the user experience.

Carrying Case

  • Design Evolution: The Bose QC Ultra comes with a hardshell case, similar to its predecessor, but with a few essential modifications. The case is designed to be compact, recognizing the needs of frequent travelers.
  • Comparison with NC 700’s Case: The QC Ultra’s case is slightly smaller than the NC 700’s due to the headphones’ fully collapsible design, as opposed to the NC 700’s lay-flat structure. This results in a more compact and travel-friendly profile.
  • Other Competitors: Compared to other models in the market, like the Sony 1000XM5 or Sennheiser Momentum 4, the QC Ultra case stands out for its smaller size and superior protection. They offer a significant upgrade over competitors’ cases, like Beats Studio Pro or AirPods Max.

Headphones Design

  • Fully Collapsible vs. Lay Flat: The QC Ultra boasts a fully collapsible design, a stark contrast to the lay-flat design of the NC 700. This feature enhances portability and influences the case size and shape.
  • Aesthetic and Ergonomic Considerations: The design choices reflect Bose’s commitment to combining aesthetics with functionality, catering to users who prioritize style and practicality in their audio devices.

Build Quality

  • Material Selection: The QC Ultra features plastic ear cups with well-engineered pivot and swivel mechanisms, accompanied by aluminum arms for durability. The headband is a mix of plastic and cushioned leatherette.
  • Comparison with NC 700: Despite their robust construction, the QC Ultra doesn’t quite match the premium feel of the NC 700, which boasts more exposed aluminum and a more luxurious headband with super-padded silicon.
  • Leatherette Quality: Though decent, the leatherette on the QC Ultra falls slightly short compared to the more supple and softer leatherette of the NC 700 and Bose QC45.

2. Comfort and Fit: Fine-Tuning the Experience with Bose QC Ultra Headphones
