The Heavys H1E True Wireless Earbuds, officially announced on September 22, 2025, are priced at $209 in the U.S., £185 in the U.K., and AU$321 in Australia, with some discounts available in certain regions. These earbuds are designed to compete with mid-range and high-end wireless earbuds such as the Samsung Galaxy Buds4, Apple AirPods Pro 3, and the Technics EAH-AZ100. The H1E earbuds are specifically tailored for a specialized listening experience, particularly for fans of heavy metal music. They use dynamic drivers to deliver a "concert-like experience," especially for sub-genres like death metal, grindcore, and deathcore. However, they are not ideal for users who prefer a more general listening experience or other music genres. The H1E earbuds come in a matte, molded plastic case that is resistant to water and sweat (IPX5 rating). The package includes multiple ear tips in various materials to ensure comfort. Users can also customize the case with designs from well-known bands like Currents, Testament, and Dream Theater. The earbuds offer up to seven hours of playback on a single charge, with a total of 24 hours of use from the case. However, this battery life is considered average compared to other wireless earbuds in the market. One of the standout features is the "Hellblocker" active noise cancellation (ANC), which is intended to block out ambient sounds. However, users have reported that the ANC does not perform well, often failing to block out background noise effectively. Additionally, when activated, it can distort the audio, making the sound muddy or tinny. The companion app allows for basic equalizer (EQ) adjustments, but it is seen as lacking compared to the apps offered by other brands. Some users have also experienced connectivity problems, particularly when using the Apple iPhone 15 Pro Max. Issues included frequent re-pairing and one earbud sometimes failing to connect. The Bluetooth 5.4 connectivity is said to be low-latency, but in practice, it is unreliable. Despite these issues, users have praised the H1E earbuds for their comfort and build quality, especially noting that the variety of ear tips allowed for a comfortable fit during long listening sessions. The H1E earbuds are recommended for users who exclusively listen to heavy metal music, especially sub-genres that emphasize heavy bass and low-end frequencies. However, for a broader audience, they may not offer the best value when compared to competitors such as the Bowers & Wilkins Pi8, Cambridge Audio Melomania M100, and Bose QuietComfort Ultra Earbuds, which offer more balanced performance across a wider range of music genres and features.
