Review: Outstanding clarity, detail and flat clean sound - Eris Accent BT 4" Wood Grain (connected via USB): These are VERY nice monitors. I always prefer monitors for my office computer speakers for the flat, uncolored response, and that is what these deliver. These replaced a pair of Mackie bookshelf monitors that gave up the ghost on the left/passive channel. There is a beautiful level of presence, detail and clarity in both vocals and individual instruments on the Eris Accents that makes it feel like I'm listening to certain songs for the first time. Very nice, and considerably better than the Mackie's. Low end is solid all the way down to where it naturally cuts based on the driver dimensions and port resonance. Of course, the rest of the low end below this point is attenuated. Will eventually make this setup a 2.1 by adding the PreSonus 8" Sub to fill out the low end. In the meantime, I added +3db on the low end eq on the speaker which helps a bit but want to get back to that uncolored sound across the full spectrum. There is plenty of volume for my home office. Set my Windows volume to 50% then dialed in the mid-level of loudness that I desired via the speaker remote (remote is line of sight only), and this results in plenty of volume control via Windows alone. Connectivity options abound. Besides USB as my main source, I'll route my Echo out to the 3.5mm port, and connect my phone on BT. This amp is really clean through the USB connection, with absolute silence between tracks on desertcart Audio using the Ultra HD quality setting. This is another area in which the Mackies lacked. Overall very good monitors at a reasonable price. Highly recommended.
Review: Amazing! Best speakers on the Market! - Well worth the price, probably the best pc speakers on the market. I’ve had them for about 7-8 months now with no problems! Easy to setup though it looks a bit intimidating compared to other speakers. Quality is clear and it’s very loud! I will note that when you first turn your pc on or start using the speakers after a while they do take about 5-10 seconds to kick on. I just call it the “warming up” phase. Again it’s quick and not that big of a deal and the quality makes up for the few second inconvenience! I can’t speak to the Bluetooth as I got the wired but if you are considering the wired version I’d go for it!

## Questions & Answers

**Q: Does this come with all the necessary cords to connect this to a computer? 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.

### ⭐⭐⭐⭐⭐ Get these instead of the PreSonus e3.5s.
*by S***N on January 2, 2026*

Pro, 1. I got these on sale for $5 more than the standard PreSonus Eris 3.5 studio monitors. 2. They have a lot more features like a remote control, a sub out for use with any home subwoofer, a 3 output option for switching between devices like TVs, record players, MP3 players, consoles, PCs and laptops. 3. A USB port to interface straight into a PC or a laptop. 4. A larger 4 inch main speakers and IMO better bass ports. 5. Better all around sound quality IMO with very adjustable highs and lows on the speaker control. 6. Has speaker grills to protect your speakers that are also removable(also look under cons for this). 7. A great look that goes well with anything from a living to an office connected to a PC. 8. It's very well rounded and works extremely well as a PC studio monitor if you're recording and listening back to recorded music tracks. 9. Very well built. 10. Very comparable to the Edifier R1280Ts Powered Bookshelf Speakers at around a similar price and they look very similar as well. The difference is the PreSonus are 50 watts RMS vs 42 watts RMS and the PreSonus comes with a sub out. 11. These speakers can get pretty loud for their size without breaking up. I was surprised. 12. Adding a separate subwoofer takes these speakers to a whole new dimension. It takes all the lowend off the speakers so they can get better clarity and midrange. Cons, 1. When not on sale these are more expensive than the PreSonus Eris e3.5s. 2. For a little more you can get the Bluetooth version of these same speakers. This didn't concern me because I'm using these as PC speakers and recording studio monitors. Others might want this feature so that why I mentioned it. 3. About the grills, they are removable and if you're using these as studio monitors or you just want more highend and midrange I'd remove them. IMO with the grills on they sound muffled. 4. Unlike the PreSonus Eris e3.5s, these speakers aren't as flat in sound like a studio ideally is, but the PreSonusErise3.5s tend to lack midrange. These speakers do have more midrange, but to get a flatter sound for recording music you may want to adjust the tone controls. I lowered the bass since I'm using a subwoofer and I increased the highend. I bought these to replace a set of PreSonus Eris 3.5s 1st Gen I got a while back that blew out. I bought these because I liked the way the PreSonus Eris e3.5s sounded, but I wanted more midrange, a sub out so I didn't have to but that expensive separate subwoofer being sold separately and more volume. This set delivers 💯. The only thing is to get that flatter sound for editing music takes a little tweaking, but it can be done. I'm using these with an older Elac 1010 60 watt subwoofer and it works great with these speakers.
