I strongly recommend this for a cabled in-ear monitoring on stage. Much better volume and sound compared to wireless in-ear monitors. Review: Great for the price - Very happy with this, simple but very effective provides clear sound with independent volume control. Takes xlr or phono jack input. Rechargeable battery is a bonus, I've used it for 2.5hours without switching off with no problem. Strong belt clip. It is a little bit bulky on the belt, particularly if sitting down but not enough to be a problem. ## Features - 【High power】 High power of headphone amplifier suited for high impedance professional headphone, make sure there is enough volume in noisy surroundings. - 【Professional in-ear monitor】Outstanding technical, sonic characteristics, high audio reproduction and no audio rendering for professional personal in-ear monitor. - 【Practical interface】XLR and TRS input connector with locking mechanism, Stereo/mono source switch depending on cable connection. - 【Strong endurance】Runs up to 12-hour long life Li-ion battery.Power and battery charging control with Led indicators. - 【Easy to carry】Solid metallic belt-pack clip,High-tech, compact and portable designs for taking everywhere. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08D8WZDTC | | Age Range Description | Adult | | Antenna Location | Stage performance, Practicing music, Studio recording | | Audio Driver Type | Balanced Armature Driver | | Battery Average Life | 12 Hours | | Battery Charge Time | 12 Hours | | Best Sellers Rank | 16 in Headphone Amplifiers | | Box Contents | Cable | | Brand Name | Donner | | Cable Features | Detachable | | Colour | Grey | | Compatible Devices | Smartphone | | Control Method | Push Button | | Control Type | Manual control | | Country of Origin | China | | Customer Reviews | 4.3 4.3 out of 5 stars (755) | | Earpiece Shape | in-ear | | Enclosure Material | Metal | | Frequency Range | 20 Hz - 20,000 Hz | | Headphone Form Factor | In Ear | | Headphone Jack | 3.5 mm Jack | | Headphones Ear Placement | In Ear | | Item Weight | 0.1 Kilograms | | Manufacturer | Donner | | Manufacturer Contact Information | Donner | | Model Name | EM1 | | Model Number | EM1 | | Network Connectivity Technology | Wired | | Noise Control | Sound Isolation | | Number of Items | 1 | | Product Features | Portable, Rechargeable | | Specific Uses For Product | Music | | Style Name | in-ear | | Unit Count | 1.0 count | ## Product Details - **Age range (description):** Adult - **Brand:** Donner - **Colour:** Grey - **Connectivity technology:** Wired - **Ear placement:** In Ear - **Form factor:** In Ear - **Headphone jack:** 3.5 mm Jack - **Included components:** Cable - **Model name:** EM1 - **Noise control:** Sound Isolation ## Images ![EM1 Rechargeable Portable Personal in-Ear Monitor Amplifier Analog Headphone Amplifier Stereo Headphone Earphone Amp Volume Control Audio Booster with XLR and TRS Input 3.5mm Output Jack - Image 1](https://m.media-amazon.com/images/I/616Yx+HKqlL.jpg) ## Questions & Answers **Q: What will i hear if i put a balanced mono XLR into it?** A: I guess you will hear a mono signal **Q: I bought a set of 80 ohm beyerdynamic dt 779 pros for work but they sound awful straight out of my mac. would this help?** A: Dear Draxx Menvone,Thank you for your interest in Donner EM1 Rechargeable Portable Personal in-Ear Monitor Amplifier.Yes, this will help to some extent. However,  you need to buy an amp or sound card to push as dt770 80Ω impedance is too high to be pushed by the computer. Donner **Q: What will i heard if i put an xlr carrying left and right?** A: This has a balanced XLR input so MONO not stereo. If you want stereo you will need to use a 1/4inch TRS Jack connection. See below info from description XLR and TRS Input XLR and TRS input connector with locking mechanism, Stereo/mono source switch depending on cable connection.XLR and 1/4” TRS input connector with locking mechanism，for connecting input signals. When the XLR is connected to balanced input, EM1 will output in the way of balanced mono. When the TRS is connected to unbalanced input, EM1 will output in unbalanced stereo ## Customer Reviews ### ⭐⭐⭐⭐⭐ Superb price/performance with a rechargeable battery *by M***Z on 11 November 2025* An amazing little piece of kit. The battery lasts forever. I strongly recommend this for a cabled in-ear monitoring on stage. Much better volume and sound compared to wireless in-ear monitors. ### ⭐⭐⭐⭐⭐ Great for the price *by N***T on 12 November 2024* Very happy with this, simple but very effective provides clear sound with independent volume control. Takes xlr or phono jack input. Rechargeable battery is a bonus, I've used it for 2.5hours without switching off with no problem. Strong belt clip. It is a little bit bulky on the belt, particularly if sitting down but not enough to be a problem. ### ⭐⭐⭐⭐ Good. Not perfect. *by T***N on 17 February 2025* What's good: It sounds just as good as my Behringer P1 but it's much smaller and lighter. It accepts jack as well as XLR. It has a rechargeable battery. It is plenty loud, and low noise. It's much cheaper than the Behringer. Not so good: The on off switch is very fiddly, you need a fingernail to work it so you can't switch it on easily on stage. I need to use the cable supplied to charge it. It doesn't charge from either of my Google USB C chargers, which is concerning. It has plastic case, whereas the Behringer is built like a tank. ## Frequently Bought Together - Donner EM1 Rechargeable Portable Personal in-Ear Monitor Amplifier Analog Headphone Amplifier Stereo Headphone Earphone Amp Volume Control Audio Booster with XLR and TRS Input 3.5mm Output Jack - Behringer P2 Ultra-Compact Personal In-Ear Monitor Amplifier --- ## 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.vn/products/234917995-em1-rechargeable-portable-personal-in-ear-monitor-amplifier-analog-headphone](https://www.desertcart.vn/products/234917995-em1-rechargeable-portable-personal-in-ear-monitor-amplifier-analog-headphone) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-10*
