SoundTeoh, also styled as SOUNDTEOH ELECTRONIC, is a Singapore-based consumer-electronics and electrical-products brand. It is associated with Hean Lee Radio Service Pte Ltd, a family-owned business established in 1957. The brand focuses on affordable, practical electrical, electronic, household, audio, and lifestyle products. While its primary market is Singapore, its distribution network extends into various international markets.

The company’s history describes SoundTeoh as having evolved from a small radio-repair and electrical business into a broader importer, wholesaler, product developer, and consumer brand 2.

The history of SoundTeoh is closely tied to its parent entity, Hean Lee Radio Service Pte Ltd.

1941–1957: Founder’s beginnings

According to the company’s official history, founder Lee Hian Cheong left Xiamen, China, in 1941 at the age of 10. After working as an apprentice in various industries, he pursued his ambition of becoming an entrepreneur.

In 1957, he established his first business, Hean Lee Radio Service, at Pasar Lane in Singapore. The original business concentrated on electrical and electronic components and radio-related services. Contemporary reporting describes the early operation as beginning with the repair and resale of radios before developing into a formal shop and eventually a larger electronics business.

1960s–1980s: Expansion

The company expanded during the following decades:

• 1967: Hean Lee Radio Service moved to Kelantan Road as the business grew.
• 1978: The company relocated again to Kelantan Lane and began importing and wholesaling products.
• 1982: A head office and showroom opened at Jalan Besar Plaza 3.

This transition from repair and service work toward importing and wholesale distribution became an important foundation for the company’s later development.

2003–2015: Corporate development

In 2003, Hean Lee Radio Service was formally registered as Hean Lee Radio Service Pte Ltd.

In 2015, its Kelantan Lane branch was closed as the company consolidated operations at its head office.

2019 onward

The company states that in 2019 it was appointed an authorised distributor for Marshall Travel and appointed Maudire Distribution Sdn Bhd as the exclusive distributor for SoundTeoh in Malaysia 1. Today, the company describes itself as an established participant in Singapore’s electronics and electrical-products industry, serving both local and overseas customers.

SoundTeoh is considerably broader than an audio-only brand. Despite the name, its catalogue encompasses a large variety of electrical and consumer products. Its current online store lists hundreds of products across categories including:

• Electrical sockets and extension outlets
• AC/DC adaptors
• Travel adaptors
• Power converters and transformers
• USB chargers and accessories
• Fans and air circulators
• LED lamps and lighting
• Night lights
• Doorbells
• Mosquito killers and pest-control products
• Multimeters and testing equipment
• HDMI cables
• Audio equipment
• Microphones
• Megaphones
• Horn speakers
• Portable amplifiers
• Car accessories
• Torches and portable lights
• Hardware and tools
• Household electrical products

The official store currently lists more than 250 products under the SoundTeoh brand, while the broader store contains products from other brands as well 4.

Audio products

Although SoundTeoh is not exclusively an audio company, audio equipment is an important part of its product portfolio. Its audio catalogue includes products such as UHF wireless microphones, desktop microphones, vocal microphone systems, horn speakers, megaphones, portable amplifiers, and PA-related equipment.

For example, the company’s FT-700 wireless microphone system supports UHF transmission, Bluetooth audio, USB playback, and has a claimed open-environment transmission distance exceeding 100 metres. The product is also listed as IMDA approved.

This makes SoundTeoh more accurately characterized as a general consumer-electronics/electrical brand with an audio segment, rather than a dedicated hi-fi or loudspeaker manufacturer.

One of SoundTeoh’s distinguishing claims is that it does not simply function as a reseller of generic products. The company states that it develops products that are difficult to find elsewhere and has the capability to develop products from scratch. It also customizes products and patents them where applicable.

Its stated philosophy is built around two major ideas: Trust and innovation. The company says these principles apply to its relationships with customers, business partners, and employees, with the broader goal of providing quality products and services that improve everyday convenience.

Safety standards

SoundTeoh places considerable emphasis on electrical safety, particularly because many of its products connect directly to Singapore’s electrical supply. The company states that it adheres to international safety standards and maintains in-house testing capabilities through its manufacturing partners. Products requiring certification are submitted to internationally recognized laboratories such as Intertek and TÜV.

There is evidence of SoundTeoh-branded electrical products appearing in Singapore’s official Consumer Product Safety registration records, which is particularly relevant for products such as multiway adaptors, plugs, and other mains-powered equipment.

SoundTeoh’s strongest differentiator is arguably its Singapore heritage. The company traces its roots back to 1957, meaning that its corporate history spans several generations. Its own materials describe the company as having operated in the electrical and electronics market for approximately six decades, while Singapore media have likewise described the business as a three-generation family enterprise.

The brand has received external recognition. SOUNDTEOH ELECTRONIC was awarded the Singapore Prestige Brand Award 2020/2021 in the Established Brands category. This distinction sets it apart from many modern electronics brands that primarily operate as online labels without a long-established local business behind them.

Relationship with Hean Lee Radio Service

It is useful to distinguish SoundTeoh from Hean Lee Radio Service. Hean Lee Radio Service Pte Ltd is the underlying Singapore company, while SOUNDTEOH ELECTRONIC is the consumer-facing brand that developed from the company’s long-running electronics business. Corporate records identify SOUNDTEOH ELECTRONIC as one of the company’s brands 5.

In simplified terms, the lineage is: Lee Hian Cheong → Hean Lee Radio Service → electronics/import/wholesale business → SOUNDTEOH ELECTRONIC consumer brand.

Brand name spelling

The unusual spelling “SOUNDTEOH” has attracted some discussion because consumers may initially read the name as “SoundTech” 6. The company consistently uses SOUNDTEOH and SOUNDTEOH ELECTRONIC as its brand names. There is some online speculation about the origin of “Teoh,” but the company’s official materials identify the founder as Lee Hian Cheong and do not provide a definitive explanation for the brand-name spelling.

Although Singapore is its home market, SoundTeoh’s business is not restricted to Singapore. Its distribution network has extended to markets including:

• Malaysia
• Indonesia
• Brunei
• Cambodia
• Dubai/UAE
• Malawi
• South Korea
• Sri Lanka
• Cyprus

and other international markets. Malaysia is particularly notable because the company appointed Maudire Distribution Sdn Bhd as SoundTeoh’s exclusive distributor there in 2019 1.

SoundTeoh operates an official online store through its Singapore website. The current store offers hundreds of products and provides direct-to-consumer purchasing, shipping, and warranty-related information.

The company also has a physical address at:

No. 1 Genting Link, #03-04 Perfect One, Singapore 349518

Its published business hours are Monday to Friday, 9:00 am to 5:00 pm.

Today, SoundTeoh can be understood as a Singapore-origin, multi-category consumer-electronics and electrical brand built on a much older family business. Its evolution can broadly be summarized as:

Radio repair → electrical retail → electronics components → importing & wholesale → product development → consumer brand → regional/international distribution → direct online retail

That history is what makes SoundTeoh somewhat unusual. It is not simply a newly created private-label electronics brand; its roots reach back to 1957, and the business behind it has operated across several generations 5.
