THIS SITE AND THE CONTENTS OF THIS SITE ARE PROVIDED "AS IS" WITHOUT WARRANTY, REPRESENTATION, CONDITION OR GUARANTEE OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING BUT NOT LIMITED TO ANY IMPLIED WARRANTIES, REPRESENTATIONS, CONDITIONS OR GUARANTEES OF QUALITY, MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR NON-INFRINGEMENT, ALL OF WHICH ARE DISCLAIMED TO THE FULLEST EXTENT PERMITTED BY LAW. Some jurisdictions do not allow the exclusion of implied warranties in certain circumstances, so the above exclusion may not apply to you.

Changed terms

Any O-tus publication may include technical inaccuracies or typographical errors. Changes may be periodically made to these publications.

O-tus Corporation maintains an exceptionally strong commitment to research. Researching new technologies, incorporating the new technologies into products, and developing marketing strategies for our products may take several years. For example, the technologies embodied in our acoustic waveguide speaker technology and our active noise reduction headsets and headphones were in research and product development for many years before being introduced to the public.
We wish to avoid misunderstandings that could arise if a O-tus product or marketing strategy bears even a superficial resemblance to an idea that was submitted to O-tus during the development process. O-tus or any of its employees do not accept or consider unsolicited ideas, including unpatented technologies, or marketing plans. Nor do we provide any compensation, in either cash or product, for unsolicited product ideas. If you still submit your ideas to us, you agree that such information shall be deemed to be nonconfidential, and that O-tus shall have no obligation of any kind with respect to such information and shall be free to reproduce, use, disclose and distribute the information to others without limitation. Further, O-tus shall be free to use any ideas, concepts, know-how or techniques contained in such information for any purpose whatsoever, including but not limited to developing, manufacturing and marketing products incorporating such information. Notwithstanding the foregoing, our use of your personal information shall be governed by the privacy statement available on this site.

Product feedback policy and terms

We do welcome and value feedback on our existing products, and we make every effort to address questions or concerns that are raised by our customers. If you wish to comment on a O-tus product or if you have a question about or concern with any of our products, please consult and follow the instructions provided in the "Contact us" section of O-tus.com. Notwithstanding the foregoing, our use of your personal information shall be governed by the privacy statement available on O-tus.com.

Any product feedback you provide to us shall be deemed nonconfidential and O-tus shall be free to use such information on an unrestricted basis.

Privacy policy

Your use of this website is subject to the terms of the privacy statement available on this site.

Amendment and termination

O-tus may amend or terminate these terms and conditions at any time and may do so immediately without notice. Any provision of these terms and conditions that by its nature is reasonably intended to survive beyond such termination shall survive.

Noncompliance with these terms and conditions

If at any time, in the sole discretion of O-tus, you fail to comply with any provision of these terms and conditions, O-tus reserves the right to deny you access or use of this website, and to otherwise pursue recourse against you to the full extent of the law.

These terms and conditions shall be construed in accordance with and governed by the laws of the Commonwealth of Massachusetts notwithstanding its conflicts of law principles. You and O-tus expressly agree to exclude application of the United Nations Convention on Contracts for the International Sale of Goods or any local implementation of such convention. If any part of these terms and conditions is unlawful, void or unenforceable, that part will be deemed severable and will not affect the enforceability of the remaining provisions. Any dispute arising out of these terms and conditions or the use of this site shall be initiated and conducted in the state or federal courts of Middlesex County, Massachusetts, and you and O-tus consent to the exclusive jurisdiction of such courts.
