Headphones are now used while working out, gaming, walking, or just lounging around. However, choosing a pair of suitable headphones is exhausting.

Namaslay helps headphone users to quickly get recommendation of the headphone they need & want and decrease the time they were looking for the ideal one in a physical store.

MyRole  My Role

I participated throughout the research process of contextual inquiry, interviews and survey. I took charge of the contextual inquiry, affinity diagram, and skeching journey maps and personas by collecting the findings. I also came up with two main design ideas which ended up as our final solution. Besides, I created Lo-fi design via Balsamiq and Hi-fi designs via Sketch.

                Barnes & Noble

At the Barnes and Noble, there were two separate locations within the electronics section where headphones were displayed.

One location had colorful packages of various brands of earbuds such as Skullcandy and Gumy.

The other section was a small counter where speakers and headphones were set up for the purpose of letting customers to try them on. There were no prices listed in this section.

                Apple store

In Apple Store, it's mostly Beats headphones throughout the store, possibly due to their branding strategies, and their deal of offering a pair of Beats with the purchase of a Macbook.

They had locations where you could listen to various sets of beats, as well as a place to hook your phone with them. Other brands offered were i.am+, Pioneer, Freedom, and Bose, often higher up on the shelves, but the Beats headphones were always at eye level.

Survey  Affinity Diagram

I want to make an informed decision

  • I want to try the physical touch before making decision
  • I want to try the audio quality before making decision
  • I want more information provided in a store
  • I need more online information

I am looking for specific features

  • I want noise cancelling
  • I want to test my own music in a store
  • I only want to check several types of headphones I intend to buy

I have preference of certain price range for headphones

  • I have a prior budget
  • I want to save as much as I can

I am an experienced headphone user

  • I think I know a lot about headphone
  • I found some information provided are not necessary


  • I'm willing to pay more for more features
  • I think the security gets in my way of seeing information
  • I go to a physical store because of geographic advantage
  • I have different headphones for different uses

UserRequirement  User Requirement

Instead of trying to solve every problem, we decided to put more efforts in solving the most important and urgent ones.


It turned out that 3 of them are the most important and have been waitting to be solved urgently:

1 Buyers come to the store with specific requirements and want their headphones to meet the requirments
2 People love to see what previous customers think about it, a.k.a customer reviews
3 People, epecially the young without high affordability, want to pay the lowest price.

As far as 4 People trying out headphones can help them to make the decision, we are informed that display of try-out racks are handled by the vendors themselves after communicating with managers in BestBuy and Barnes & Noble, rather than the physical store. So considering the feasibility, we compromised to a navigation part to guide people to try-out racks instead of changing the try-out rack itself.

personas  Personas & Journey maps

In order to focus more on specific user groups while identifying problems and designing solutions, we attempted to use 3 personas by synthesizing data collected about people from surveys and interviews.

Journey maps eanble us to think from users' perspectives by taking notes of their feelings and actions along their purchase experiece.

User Evaluation  User evaluation

In this step, we showed all of three different sketches and working flow to users, during when they were asked how they think the sketched idea works. In order to avoid order-bias during the study:

A: Kiosk   B: LED   and C: Personal assistant
We switched the order of presentation between ABC, CAB, BCA, etc for various users.

We started with a quick introduction for the participants, explaining that they were looking at concepts for various systems that may improve the headphone shopping experience. We made sure to inform them that any comments, even negative ones, would be useful for improving and refining these designs.

Cognitive Walkthrough  Cognitive Walkthrough

We printed the Lo-Fi wireframes above and showed them to 3 experts. Before every page, we asked them what they think should appear; when they browsed the page, they were invited to think aloud to tell us what their thoughts about the page.

Along the process we were observing their facial expressions and taking notes of their feedbacks.

Then I began to polish our Hi-Fi prototype in Sketch.


UsabilityTest  Usability test

We presented the Hi-Fi prorotype to 9 people, 3 experts for heuristic evaluation, 6 headphone buyers for usability test. For the usability tests, we went to Georgia Tech Barnes & Noble to help users to be immersed more in the shopping environment.


Iterative Design  Design Improvement

Based on feedbacks from heuristic evaluation and usability test, we began to improve design.
