Contact Us: M-T 8am to 4:30pm, Fri 8am to 3pm 1.800.872.5677 [IMG: certified] Contact Form [IMG: certified] [H2] Frequently Asked Questions How can I contact Koss Corporation? You can reach Koss Corporation's US headquarters from the US by calling 1-800-USA-KOSS, by writing: Koss Corporation 4129 N. Port Washington Ave. Milwaukee, WI 53212, or fill in our contact form and a Koss representative will get in touch with you.Where is Koss Corporation located?The Koss International Headquarters is located in Milwaukee, Wisconsin (4129 N. Port Washington Ave. Milwaukee, WI 53212).How long has Koss Corporation been around?Koss Corporation was founded by John C. Koss in 1953 as a television rental company. In 1958, John Koss, along with his partner Martin Lange JR., developed the world’s first stereophones, the SP/3. Today, Koss offers a complete selection of over 40 different models of stereophones, ranging from our top-of-the-line electrostatic stereophones, noise reduction systems, and infrared and radio frequency stereophones to our line of lightweight portables. Within the past several years, Koss has branched into the field of multimedia with a complete line of computer speakers, microphones, accessories, and boom microphone stereophones.What is Koss Electronics?The entity Koss Electronics no longer exists. Koss Electronics manufactured consumer electronics products such as: home theaters, DVD players, portable media players (MP3), table top stereo systems and boom boxes. [H4] REPAIRS Can I get my older Koss stereophones/speakers fixed?In most cases, if we have the parts still available, we can repair your old Koss product. Please call us at 1-800-USA-KOSS and talk to a customer service representative for part availability and pricing. [H4] SECIALTY STEREOPHONES What is Active Noise Reduction (ANR) Technology?Active noise reduction technology in stereophones creates an invisible shield between the listener and the droning sounds of the world by stopping low frequency noise before it reaches the ears. Tiny microphones are embedded in the stereophone ear cups. These microphones read the surrounding low frequency noise and transmit information about those undesirable sounds to a processor in a pocket sized control case. The processor, in turn, generates mirror image anti-waves that are 180 degrees out of phase and relays those anti-waves back to the stereophones. When the offending sound waves encounter the waves generated by noise reduction technology, the two counteract each other at the wearer’s ear. The offending hum and buzz is reduced and a peaceful listening environment is created where once there was only noise. Lawn mowers, jet engines, crowded environments, vacuum cleaners, computer fans or any other low frequency noise below 1000 Hz can be reduced by an average of 10dB by Koss’ Noise Reduction Stereophone the Quiet Zone 2000. Quiet Zone noise reduction is even greater for noise below 200 Hz, offering at least 15dB of protection against low frequency noise. [H4] SPECIFICATIONS What does frequency response mean?The range of sound reproduced by the stereophone or speaker from the lowest bass to the highest frequency. The broader the frequency response range of a product, the greater highs and lows it can reproduce.What does it mean when a product is amplified?An amplified product is one that operates on its own power supply (AC or batteries). This applies to certain computer, portable, and home speakers and stereo systems. Conversely, unamplified products must be connected to an amplified sound source in order to operate.Why is it important that a stereophone or pair of speakers be magnetically shielded?If the magnets that power a pair of stereophones or speakers were not shielded, they could cause interference, a distorted picture or even data loss when used with a TV, VCR or computer. All Koss Stereophones and Speakers are magnetically shielded. [H4] STEREOPHONE SPEAKERS Are Koss stereophones and computer speakers compatible with different types of computers?Yes. Koss stereophones and computer speakers will work with any computer that has a 3.5 mm headphone/speaker jack attached to its sound card or CD-ROM, regardless of whether it's a MAC or a PC.How can I order replacement ear cushions for my Stereophones?Yes, replacement earcushions are available for most models.Please select the "find replacement ear cushions" link on the left navigation bar to find your model. For pricing and availability of discontinued products, please contact our Consumer Sales department at 1-800-USA-KOSS.How is a dual volume control different from a balance control?A dual volume control incorporates volume control and balance control into one control. It allows the listener to adjust the sound level in either stereophone ear cup independently of each other. A balance control works in conjunction with a volume control to limit or increase the amount of sound that reaches a listener’s ear. A dual volume control is also a great feature for people with partial hearing loss in one or both ears.What's a dual entry cord versus a single entry cord?A dual entry cord splits into a Y with each end attaching to an ear cup. A single entry cord attaches to the stereophone at one ear cup only for greater freedom of movement.What are the advantages of a metal headband over a plastic one, or vice versa?It is mostly a matter of opinion. Each has their own benefits. A metal headband is more durable over the long run while a plastic one offers greater comfort during extended listening. The preference is a personal one.What does side-firing mean?Side-firing is a term used to describe ear-buds that go into the ear sideways, directing sound into the ear canal for improved bass response.What is the benefit of a dual volume control?A dual volume control enables the listener to adjust the volume on each stereophone cup individually. This is a great feature for those listeners who are hearing impaired in one or both ears.What is the difference between an open and a closed ear cup?An open ear cup provides a more hear-through, airy sound while a closed one delivers deeper bass response. Most commonly, a closed ear cup is paired with a closed (circumaural) vinyl or leatherette ear cushion for maximum isolation while listening and an open ear cup is paired with a foam ear cushion for greater sound transparency.What is the difference between infrared and radio frequency (RF) cordless technology?Infrared is cordless technology that operates on a beam of infrared light transmitted from a transmitter connected to the sound source to the stereophone. Listeners must remain within the line of sight from the transmitter to the stereophones or the signal is broken. A remote control for a TV operates on infrared technology. Radio frequency, on the other hand, operates on a radio signal transmitted from a transmitter connected to the sound source to the stereophone. Listeners may move freely, in any direction out of sight of the transmitter, up to a designated amount of space. Neither technology is necessarily better than the other. It is mostly a matter of personal choice. Infrared is generally less susceptible to interference than RF, while RF allows the listener to roam more freely throughout their home. When considering a cordless purchase, think about how you would use it. If you are more inclined to listen in one room only, the infrared unit offers a stronger signal with less interference. If you prefer greater freedom of movement, an RF unit will enable you to move about freely from room to room. Just as sound is subjective, so is how you choose to listen.Who uses a balance control?Anyone who has partial hearing loss in one or both ears can use a balance control to adjust the balance of sound to either stereophone ear cup, customizing how the sound reaches their ears.

Your Diagnosis
Before revealing the machine’s verdict, predict the BS score for each signal. Higher = more BS (more fluff, less verifiable substance). Drag each slider, then submit to compare your judgment against the engine.
Stuck? Reveal the heuristic lens — how the deterministic page-auditor reads each signal (no AI, pure pattern rules)
These are the structural rules a local, deterministic auditor applies — the same lens you can use to judge each signal. They describe what to look for, not this company’s result.
Classify each sentence as substantive or hollow. Grounding markers — numbers, currencies, dates, technical units, named entities — outweigh marketing adjectives. When fluff sits right next to hard evidence, the fluff is forgiven.
Pull the main entities out of the H1, then check whether they actually recur through the body. A page that announces one thing and then talks about another drifts. Headings with no real sentences underneath read as pseudo-substance.
Count trust words (review, testimonial, rating, verified) against real outbound proof links (Google, Trustpilot, Clutch, G2, Yelp). Lots of trust language with zero verification links is trust theatre. Unlinked logo galleries count against it.
Look at how much sentence length varies. Natural writing varies its rhythm; templated or mass-produced copy is statistically uniform. Very low variation reads as commodity content — unless unique named entities break the pattern.
Inspect the JSON-LD. Is there an Organization or Person schema, and does it carry sameAs links to real external profiles (LinkedIn, socials)? Missing schema or no identity declaration signals an anonymous entity.
Want to apply this lens yourself? The free BS Indicator Chrome extension runs these heuristic checks live on any page. Bear in mind it is a single-page, deterministic tool — it relies only on pattern rules for the page in front of it and does not perform the cross-page semantic correlation this audit uses, so its readout is a starting lens, not the full verdict.

Ecommerce & Online Retail BS: Koss Stereophones (koss.com)
Koss is a benchmark for low-BS ecommerce, leveraging deep technical heritage and physical transparency to validate its claims. The site avoids the ‘Direct-to-Consumer’ fluff typical of modern audio brands, opting instead for technical specifications and verifiable historical authority. It is a rare example where the product’s history and specs do the heavy lifting for the marketing.
Implement comprehensive Organization and Person schema to programmatically link John C. Koss and the Milwaukee headquarters to the brand identity. Connect the review display to a third-party verification platform to increase the proof_links_count. Update the ‘History of Koss’ section with more recent milestones to avoid the ‘stale’ temporal anchor as the content moves toward the 2026 system date. Clarify the ‘Legendary’ descriptor by linking it directly to specific industry awards or historical patents.
The site perfectly aligns with the Ecommerce & Online Retail category, specifically focusing on consumer electronics and specialized audio equipment. The content demonstrates a clear transition from high-level branding to granular product specifications and vertical-specific collections like healthcare and education.
“The score of 19 is driven by excellent semantic coherence and high information density, which are rare in online retail. The minor points assigned are due to the missing structured data (schema) and the lack of external proof links for the review count, rather than any presence of deceptive marketing or fluff.”
