KIMAFUN 2.4G Wireless Fitness Microphone System Package Included: Headset Brace * 1 Transmitter microphone * 1 Receiver * 1 Windscreen Foam * 2 USB Sound Card * 1 6.35mm Adapter * 1 Dual USB Charging Cable * 1 Y Splitter * 1 Carrying Bag * 1 Review: I have had this microphone for three years I use this to teach Pilates and Yoga. I once used to teach 150 in a large gymnasium and the sound was amazing. I recommended to others. Yes the headset requires a little finagling but so do others and it’s easy to remedy. I would say mine holds a charge about three hours. Just peaked in to see if they were still making this. I’m going to purchase another one because I am beginning to lose a little bit of charge length but …it’s three years old, and I have put it through the wringer. Just don’t want to get stuck without one if it goes belly up. So I will use the new one and keep this one as a backup. Highly recommend . Love, love, love the case it comes in. Review: Easy to use.

I will be teaching Jazzercise but do not want to use a windscreen** A: If you sweat gets in the microphone it will damage the unit. I went through a half dozen of these before I came up with an answer to the problem. The windscreen is the first line of defense working as a sweatband. Not to mention heavy breathing. **Q: How can you connect this to an iPhone and use it in a pool?** A: The system works with an iphone. What you need to bring is an original lightning to 3.5mm adapter cable, such as ASIN-B01LXJFMGF Only the condenser and gooseneck can be submerged in water, the transmitter part is not waterproof. So if you're doing some movement teaching by the pool, that's fine. But it can't be taken into the water. **Q: Can i use this charger with my fitness wireless microphone, kimafun 2.4g wireless waterproof headset microphone with transmitter and 3.5mm receiver,** A: i don't believe so, its only compatible with what it comes with. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by T***L on 13 February 2026* I have had this microphone for three years I use this to teach Pilates and Yoga.

Works great for my fitness class! ### ⭐⭐⭐⭐ Review *by C***T on 29 January 2026* I teach spin classes and the sound on this headphone set it perfect! I gave it only 4 stars because the mic itself is a little heavy, so I am constantly having to adjust it. BUT the noise level and durability are way better than ones I have used in the past so I just go with it. ## Frequently Bought Together - KIMAFUN Headset Wireless Microphone System, No Need Bluetooth, Waterproof Head Mic for Fitness Instructor, Teaching Online, Yoga Classroom, Spinning Coach, Speaker, iPhone, Android Phone, G100-1 - Bietrun Wireless Microphone Headset, UHF Wireless Headset Mic System, 160ft Range,1/8'' and 1/4'' Plug, for Speakers, Voice Amplifier, PA System(Not Supported AUX/iOS) - XIAOKOA UHF12 Wireless Microphone Headset, 160ft Range, Dual Micro USB Charging, Suitable for Teaching, Stage Performers, Fitness Instructors --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/342708879-fitness-wireless-microphone-2-4g-wireless-waterproof-headset-microphone-transmitter](https://www.desertcart.us/products/342708879-fitness-wireless-microphone-2-4g-wireless-waterproof-headset-microphone-transmitter) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-22*
