Challenge
The Sennheiser Brand's consumer devices are premium, technical and feature-rich, which can create friction for shoppers. Customers often need to compare wireless technologies, understand Bluetooth, noise cancellation, battery life, compatibility, setup, spare parts and product specs before buying. The challenge is that many of these details are obvious to experts, but not always clear to customers. Even small moments of uncertainty can slow shoppers down, create hesitation and lead to more questions before they feel confident enough to purchase.
Results
The Sennheiser Brand deployed preezie’s AI Shopping Assistant sitewide on their Australian consumer business website on product detail pages to help shoppers get faster answers, understand technical features and buy with confidence, driving a 5% - 10% usage rate, 150% - 250% higher revenue per visitor and a 2.5x - 3.3x increase in conversion rate.
Key solution
AI shopping assistant
“The AI Shopping Assistant is helping us remove friction for customers, especially because our products can be quite technical. The transcript insights have been extremely useful. They show us what customers are actually asking in their own words, including questions we may have assumed were obvious.”
About The Sennheiser Brand
The Sennheiser Brand lives and breathes audio. They are driven by the passion to create audio solutions that make a difference. This passion has taken them from the world’s greatest stages to the quietest listening rooms – and made Sennheiser the name behind audio that doesn’t just sound good: It feels true. In 2025, the Sennheiser brand celebrated its 80th anniversary. Since 1945, they stand for building the future of audio and bringing remarkable sound experiences to customers.
While professional audio solutions such as microphones, meeting solutions, streaming technologies, and monitoring systems are part of the business of Sennheiser electronic SE & Co. KG, the business with consumer devices such as headphones, soundbars and speech-enhanced hearables is operated by Sonova Holding AG under the license of Sennheiser.
The strategy
The Sennheiser Brand used preezie’s AI Shopping Assistant in two key ways:
-
1. As a sitewide AI chatbot to support general product discovery, comparison and customer questions
-
2. Embedded on product detail pages to answer product-specific questions in context
Site Wide Chatbot
Embedded on Product Page
The strategy focused on helping shoppers:
-
- Understand technical specifications in plain English
-
- Compare products more easily
-
- Get immediate answers about Bluetooth, battery life, ANC, compatibility and setup
-
- Reduce hesitation before purchase
-
- Avoid leaving the product page to search for answers elsewhere
-
- Give the eCommerce team better visibility into what customers were actually asking
This made the AI Shopping Assistant both a conversion tool and an insights tool.
The launch & early insights
Once live, the AI Shopping Assistant quickly surfaced the kinds of questions customers were asking during the buying journey.
Across the transcript snapshot, customers asked about:
-
- Bluetooth and wireless connectivity
-
- Battery life and charging
-
- Noise cancellation and sound quality
-
- Smart Control app setup
-
- Product compatibility
-
- Cables and TV connection
-
- Stock, pricing and promotions
-
- Warranty and support
-
- Replacement parts and accessories
-
- Product comparisons and recommendations
The most repeated question theme was Bluetooth and wireless functionality, with customers asking questions such as:
-
- How does your Bluetooth wireless work?
-
- Is this compatible with Bluetooth adapters?
-
- Describe the Bluetooth pairing process.
-
- Does it support Mac devices?
-
- Is this compatible with iPhone?
-
- What is the wireless range?
These questions show that customers were not just browsing. They were actively trying to understand the product before making a decision.
The Sennheiser Brand has already used insights from AI transcript data to update product titles, descriptions and other on-site content.
Business impact
The Sennheiser Brand saw a 5% usage rate, showing meaningful customer engagement with the assistant across the site.
More importantly, AI-assisted shoppers delivered a 150% - 250% increase in revenue per visitor and a 2.5x - 3.3x increase in conversion rate.
That suggests the assistant was being used by high-intent shoppers at critical decision-making moments — helping them get answers, reduce uncertainty and move closer to purchase.
For a technical product category like premium audio, this is especially valuable. The assistant does not just recommend products. It helps translate product complexity into customer confidence.
Beyond performance: insight for the wider business
One of the biggest benefits for The Sennheiser Brand was not just the performance uplift. It was the insight from transcripts.
The AI Assistant gave the team a direct view into what customers were confused about, what they cared about and what information may need to be clearer on product pages.
For example, the team discovered that customers were repeatedly asking whether wireless headphones had Bluetooth. That is a simple but powerful insight.
It shows that customers may not always interpret product language the same way a brand or eCommerce team does.
These transcript insights can help The Sennheiser Brand improve:
-
- Product page content
-
- FAQs
-
- Merchandising
-
- Customer support resources
-
- Product education
-
- Campaign messaging
-
- On-site navigation
-
- Conversion rate optimisation
Instead of guessing what customers need, the team can use real customer questions to improve the shopping experience.
