Is it rca trs or xlr?** A: It depends on which speakers you order. The 3.5 and 4.5 come with everything necessary, but the 5 and higher definitely do not come with everything you need. Just the speaker and AC adapter. **Q: Is the the Presonus E3.5 woofer speaker cone unprotected? It appears to have no fabric covering as many speakers would have.** A: Take a piece of t-shirt and bring it back and forth between your face and the monitors.. you will hear that even something like a tshirt of pantyhose, has a considerable effect on the sound projection. Also, having grills on the speaker looks cheap imo.. **Q: I am a Motivational Speaker, can I use these with a microphone when speaking to an audience of 75 people?** A: There are better choices for that -- you want speakers with a built-in mic preamp, and probably higher wattage amplifiers. You may also want folding speaker tripods. I suggest you puchase speakers designed for this, with a tripod screw hole on the bottom, and XLR mic inputs. For example, Bose EONS sound amazing for music as well. You may also wish to purchase a good wireless mic. Think of it as a system. The size of the room and the audience determine the required size and power of speakers. **Q: Do the Eris 4.5 mute themselves when a headphone is connected?** A: Ideally they should, unless you’re using the Presonus Audiobox (or any other audio interface) and you connect headphones to that. In which case, they won’t mute. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great speakers *by G***S on 13 April 2026* ### ⭐⭐⭐⭐⭐ Buen sonido, calidad precio *by J***A on 15 January 2026* Justo lo que buscaba, excelente para iniciar con mi pc en proyectos de música, gracias ### ⭐⭐⭐⭐⭐ Clear audio *by R***R on 12 November 2025* ## Frequently Bought Together - PreSonus Eris 3.5BT Studio Monitors, Pair — 3.5" Inch Powered Bookshelf Speakers, Stereo, Desktop Computer, Near Field Music Production, Audio Mixing Recording - Ekkogo Pair of Studio Monitor Isolation Pads Premium Acoustic Foam to Elevate Audio Ideal Speaker Foam for 3-4.5 Inch Speakers Enhanced with Vibredux HD Foam for Superior Isolation - Vondynote Set of 2 Desktop Clamp Speaker Stands Short Studio Monitor Stands Height Adjustable --- ## 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.pe/products/650404020-eris-3-5bt-bluetooth-studio-monitors-pair-powered-active-monitor](https://www.desertcart.pe/products/650404020-eris-3-5bt-bluetooth-studio-monitors-pair-powered-active-monitor) --- *Product available on Desertcart Peru* *Store origin: PE* *Last updated: 2026-05-07*
