Because this receiver output is about the same level as a wired mic. It must be plugged into a 1/4'' speaker input designed for a mic connection. If your speaker has only 3.5mm line inputs which require a higher level signal than a mic provides, the mic will be not suitable to be used with it, even you add an adapter. The sound will be soft and hard to be heard. **Q: Can I plug the receiver into my iPhone, audio mixer, or Mac to record the audio?** A: Sorry, it works with only audio mixer that has 1/4" mic jack. If you need a mic to use with Mac, we have the K031 (Asin: B074C125TN) USB wireless lav mic. But neither of them will work with iPhone. **Q: can it be used for singing** A: It will be more suitable for speaking than singing. We would recommend the handheld mic K025(ASIN:B0795PNCBG) or K035(ASIN:B01MT6AAIC) for singing. All these mics need to work with speakers/amps that has 1/4'' mic input. ## Frequently Bought Together - FIFINE Wireless Microphone System, Wireless Microphone set with Headset and Lavalier Lapel Mics, Beltpack Transmitter and Receiver,Ideal for Teaching, Preaching and Public Speaking Applications-K037B - ttstar Wireless Microphone System Headset/Stand/Lavalier Mic with Rechargeable Bodypack Transmitter Receiver for PA Speaker, Camera, Recording, Teaching, Church - 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) --- ## 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.ro/products/82152731-wireless-microphone-set-k037b](https://www.desertcart.ro/products/82152731-wireless-microphone-set-k037b) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-09-17*
