I'm looking for wireless headsets that offer great sound quality and comfort for prolonged use. Ideally, they should have features like noise cancellation, long battery life, and compatibility with multiple devices. Additionally, I'd like to know about the available designs and color options you have in terms of both over-ear and in-ear styles. Please share any details about pricing, bulk order discounts, and lead times for delivery. Looking forward to your quick response!
