Review: Great while it works but fell apart after a year of use - Consider that you need to buy a new one every year The rubber on the bone induction speaker part detached and has started to let in water Review: I purchased the H2O Interval to replace a 'HIFI Sound Waterproof MP3 player for swimming' that you can also find on desertcart. I wanted the convenience of playing music from Apple Music/Spotify/desertcart Music/Podcasts, without having to buy and download them onto the device. The design of the device is great: it's sturdy where it fits against your head and holds the Apple Watch face and the bone conduction pads are compact and comfortable against your head. The bar that holds the watch in place is rubberised to accommodate different sizes of Apple Watch faces. The volume/skip track controls are easy to find in the water and essential as Apple Watch faces do not work when in water and neither does Siri (unless your phone is nearby or you have the cellular version). I spent ages researching different options and ultimately settled on this because of the Apple Watch integration. Things to bear in mind before buying the H2O Interval: - The device is limited to swimming only as the bone conduction pads and holder for the Apple Watch face attach to goggles. - The device does nothing without an Apple Watch attached. Your watch is the source of music/podcasts. - Apple Watches are designed to get wet but can get water damaged so there is always that risk to consider. - Your Apple Watch cannot track heart rate and other vitals whilst swimming as it is not attached to your wrist. H2O do have their own swim-tracking app though for length counting and goals. - Make sure you've downloaded music/podcasts to your watch in the Watch app on your iPhone. These sync and update automatically so you do not need to always do this. ## Features - BASS AMPLIFIED SOUND: The Surge earphones provide a premium sound quality with more bass than any other waterproof earbuds on the market, while sound-isolating; the watertight earplugs provide clear warm sound and dynamic bass response; Powered by Surge?s waterproof neodymium drivers, which delivers plenty of volume without any distortion - International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions - DESIGNED FOR SWIMMERS: The headphones come with an ergonomic sheared shape which sits flush with the ear and is designed to promote proper alignment and fit, plus less drag in the water, the integrated goggle loops make it easy to attach and remove the case from almost any swim goggles; Includes five sets of Elastomer earplugs (XS-XL) and one set of ?Tree Tip? earplugs ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07ZDMJ75K | | Additional Features | Noise Cancellation, Sweatproof, sports-and-exercise, water-resistant | | Age Range Description | Adult | | Antenna Location | Exercising, Swimming | | Audio Driver Type | Dynamic Driver | | Battery Average Life | 6 Hours | | Battery Charge Time | 6 Hours | | Best Sellers Rank | #35,114 in Electronics ( See Top 100 in Electronics ) #1,983 in In-Ear Headphones | | Bluetooth Range | 10 Meters | | Bluetooth Version | 5.0 | | Brand | H2O Audio | | Built-In Media | Wireless Charging Case | | Cable Features | Tangle Free | | Carrying Case Battery Charging Time | 6 Hours | | Carrying Case Color | Blue | | Carrying Case Material | Plastic | | Color | blue | | Compatible Devices | Apple Watch Series 8, 7, 6, Apple Watch Ultra | | Connectivity Technology | Bluetooth | | Control Method | Touch | | Control Type | Media Control | | Controller Type | wireless | | Customer Package Type | Rigid" or "Protective | | Customer Reviews | 3.5 3.5 out of 5 stars (478) | | Earpiece Shape | Rounded Tip | | Enclosure Material | Silicone | | Frequency Range | [20 Hz - 20,000 Hz with bass emphasis] | | Global Trade Identification Number | 00850000259157 | | Headphone Folding Features | In Ear | | Headphone Jack | 3.5 mm Jack | | Headphones Ear Placement | In Ear | | Impedance | 16 Ohms | | Is Autographed | No | | Is Electric | No | | Item Weight | 10 Grams | | Manufacturer | H2O Audio | | Model Name | INT5-AW-SG8-BCH-FBA-PARENT | | Model Number | HEADPHONES | | Noise Control | Active Noise Cancellation | | Number of Items | 1 | | Series Number | 8 | | Specific Uses For Product | Sports and Exercise | | Style Name | Modern | | Subject Character | no character | | Theme | Sports | | UPC | 850000259157 | | Unit Count | 1 Count | | Water Resistance Level | Waterproof | | Wireless Technology | Bluetooth | ## Product Details - **Brand:** H2O Audio - **Colour:** blue - **Ear placement:** In Ear - **Form factor:** In Ear - **Impedance:** 16 Ohms ## Images ![Interval Waterproof Swimming Headphones for Apple Watch – Bluetooth IPX8 Underwater Sports Earbuds with Bass-Amplified Surge S+, 6-Hour Playtime - Image 1](https://m.media-amazon.com/images/I/510f+FTCUsL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: How secure is the apple watch in the clip? I'm doing ocean swimming** A: It is surprisingly secure. Ive also come to use the headset with the watch bands on my wrist and not holstered in the clip so I can see stats and manipulate controls more easily **Q: Why do I loose signal 1/2 way down the lap?** A: You have likely paired your Interval with the phone and not the watch! If you are not using the watch - and want to use your phone - put the phone half way on the lane to improve the range. For more support - please email H2O Audio: support@h2oaudio.com **Q: Does this connect Bluetooth to my Android phone? How well does it work for swimming laps?** A: I'm pretty sure it connects to any bluetooth, I have an iphone. The older model worked great, but the newer one I had to replace it with, doesn't work more than 10 meters for me. I swim laps in a 25m pool, so it's pretty useless. **Q: The headphones work well but it’s not tracking my laps on the app, what am I doing wrong?** A: Hi Jill - please email us at support@h2oaudio.com and we can get you tips for improving the tracking. We are also about to release a new app version! ## Customer Reviews ### ⭐⭐⭐ Great while it works but fell apart after a year of use *by C***R on 30 April 2023* Consider that you need to buy a new one every year The rubber on the bone induction speaker part detached and has started to let in water ### ⭐⭐⭐⭐⭐ Review *by W***N on 29 October 2023* I purchased the H2O Interval to replace a 'HIFI Sound Waterproof MP3 player for swimming' that you can also find on Amazon.

In piΓΉ noto che le cuffie non si possono cambiare, quindi se si lesiona il filetto delle cuffie devi buttare tutto. Prezzo di 129 ma la mia valutazione Γ© di 15 euro.
