Description

PreSonus Eris-series studio monitors are used worldwide by audio engineers and producers who need to hear every detail of their recordings. Eris 3.5BT media reference monitors deliver studio-quality sound in an elegant, compact form factor that makes them ideally suited for use as bedroom studio speakers, turntable and record player speakers, video post-production speakers, or high- fidelity audio monitors with Bluetooth. With 25 watts per side of onboard power, the Eris 3.5BT reference monitors pack a serious punch, while still delivering clear, accurate audio. The weave of the 3.5-inch woofer results in tight bass that you can feel, while the one-inch silk-dome tweeter produces refined high-frequencies and is designed to radiate sound with a wide pattern, creating a large optimal listening area. Improved speaker voicing over the previous first generation design delivers richer lows and a smoother crossover transition for articulate, accurate transient reproduction throughout the frequency range and a less-fatiguing listening experience. A convenient front- panel knob sets the level of both the power amp and the loud, clear headphone amplifier, with its front-panel jack. With four types of inputs, including fast, reliable, stereo Bluetooth 5.0 connectivity, it's easy to connect just about any audio source to your Eris 3.5BT reference monitors. High- and low- frequency controls let you easily adjust the Eris speaker's frequency response to compensate for the acoustics of your space and create the most accurate sonic reproduction possible. Need a little more low end? Put some boom in your room with an Eris Sub8 BT to build a perfectly matched 2.1 sound system that fits almost anywhere.

    • Great solution
Size: 3.5" Bluetooth Color: White
I bought these for use with a projector set up in my living room. These are the perfect solution. More than loud enough, good depth of sound, and good price point. Bluetooth connects and disconnects seamlessly.

As a music producer, these are amazing quality for the price. I wanted some smaller but decent monitors for my gaming setup and I feel like I got more than what I paid for. I have other monitors like Yamaha HS8’s and some other 6.5” monitors for my music setup, and these 3.5” monitors match up pretty well at certain frequencies. They are very loud, but not overwhelming or muddy sounding when turning the volume up. They are punchy and have decent sounding lows, I’m almost interesting in trying them out in my music studio they impress me so much. Out the box they feel very light, which is why others seem to say they don’t feel “quality.” But this works in my favor because they fit very nicely on my shelf above my desk without causing the shelf to sag like my other monitors would. The Bluetooth works great and sounds just as good as they do when plugged in with some TRS cables. I seen some people say they hear a humming noise when plugging them into the 3.5mm jack. In my personal experience I hear this humming noise when plugging ANY 3.5mm sound device into my PC or device. I think the jack port on these monitors are there to be an extra way to connect, and not the main source of input. Get a cheap interface and plug them into the back ports. You will not be disappointed. I give these monitors a solid 5/5. They met my expectations and more and I would recommend these to anyone. Overwhelming quality sound for the price point! ... show more

    • SUPER CRISP AUDIO
Size: 3.5" Bluetooth Color: Black
I got this for mixing audio and I absolutely love them. They give true EQ feedback without boosting the lows or the highs. There are EQ knobs in the back for Treble and Bass if you are looking to use them just for music, movies or gaming. They are amazing quality and I highly recommend them. Great value for what you pay ... show more

    • Really great sound for a great and competitive price!
Size: 3.5" Bluetooth Color: White
So far so good, can’t say I have any issues with the speakers, I’ve only had them for two days but so far I’m really loving them. Not only do they look beautiful and sleek and simple and modern without being too much but obviously super easy to plug-in and get going. Came with a good amount of options for wiring although for some reason, I thought it came with 1/4 inch speaker cables for balanced sound, but I guess not. But it does at least come with RCA cables for the unbalanced option, I’ll just have to buy some new cables. Other than that, loving them and the option for Bluetooth is pretty dope, though I haven’t used it yet. Audio definitely sounds better than my attached video, super fool in person. ... show more

    • Great Budget Speakers
Size: 3.5" Bluetooth Color: Black
I normally use my arctis nova headphones but I do love to have some spare speakers in case I want to kick back. With that said, this was a great budget speaker combo that works flawlessly. It doesn't have immaculate sound as it's not a premium speaker, but in the time I've had it, I've not encountered any issues whatsoever. Setup is fairly simple, it's plug and play and doesn't get any easier than that. There is no remote control but that's not an issue for my use case scenario. If you need a remote you should look for a different set. Surprisingly enough like I said earlier, the sound quality is good enough for me. It's just for me to hear and no one else and I'm satisfied with it. ... show more

    • What a nice speaker for my room!
Size: 3.5" Bluetooth Color: White
PreSonus Eris 3.5-inch Media Reference Monitors with Bluetooth (White) - My Honest Review I'm not a professional musician or anything, but I wanted some decent speakers for my computer setup. I mostly use them for listening to music while I work, watching YouTube videos, and sometimes playing games. I was tired of the tinny sound from my old computer speakers, and I wanted something with a bit more oomph. After doing some research, I decided to try the PreSonus Eris 3.5s with Bluetooth. First off, they look great. The white finish is clean and modern, and they fit nicely on my desk without taking up too much space. Setting them up was super easy. I mostly use the Bluetooth connection, which paired instantly with my phone and laptop. No complicated setup required! The sound quality is a huge improvement over what I had before. Everything sounds much clearer and more detailed. The bass is surprisingly good for speakers this size – it's not going to shake the walls, but it adds a nice fullness to the sound. I can actually hear the different instruments in music now, and dialogue in videos is much clearer. I also like that there are some controls on the front of one of the speakers. It makes it easy to adjust the volume without having to mess with my computer settings. I haven't really used the EQ settings much, but it's nice to know they're there if I need them. Honestly, for the price, I'm really impressed. They're a big step up from basic computer speakers, and they sound great for everyday use. If you're looking for good quality sound for your home office or bedroom without breaking the bank, I'd definitely recommend checking these out. Pros: Easy to set up, especially with Bluetooth Great sound quality for the price Look nice on a desk Convenient front controls Good bass for their size Cons: Not super powerful – probably not ideal for large rooms or parties (but that's not what I bought them for) Bottom line: If you’re like me and just want better sound for everyday use, these are a great choice. I'm really happy with my purchase. ... show more

    • Good Speakers - And the bluetooth "power saver" CAN be disabled!
Size: 3.5" Bluetooth Color: Black
I decided to upgrade my old Gen1 Echo Show 8 (which had an audio-out port) with a new one, which does NOT have an audio-out port (which is ridiculous, but another issue). For the first week or so, I was repeatedly frustrated by the fact that they'd go into "power-save" mode about every half-hour, which meant that I was not getting some of my notifications (they wake up quickly, but some of my notifications are quite short). Looking through the instructions, I didn't see any way to disable it, and doing further research, found it's a common "feature" in bluetooth speakers - even ones that do NOT operate on batteries. Really? Why? Do speakers REALLY draw that much current from my home? I don't think so. Regardless, unable to find reasonably-priced speakers without this "feature", I was looking into getting an adapter to take the bluetooth signal and put it into analog. That way I could bypass this "feature". While examining the ports to see what sort of adapter I'd need, I noticed this tiny little switch that said "Standby". That piqued my interest, so I dug back into the instructions. It ONLY appears in the diagram where it shows what the buttons and ports do (not for example, in the troubleshooting section, which was where I'd searched earlier). It was labeled "Used to engage/disengage a power save mode that adheres to the EU Energy Efficient Products Directive to conserve energy when not in use." SMH Totally did NOT register when I first read the instructions. Turns out, that's the fix! Kudos to the designers for putting in a fix for a law that's completely unnecessary. However, it might be wiser to ship them with it already in the "off" position. If that's not illegal! Aside from that glitch, I'm pretty happy with the speakers so far. They connected easily to my Echo 8, they sound pretty good, and I've had no other issues - yet. ... show more

I’m upgrading from a set of PC speakers from 20 years ago (lol) They were great speakers in their time. The Eris speakers have changed everything. I’m hearing things in songs I’ve never heard before. If you’re thinking about upgrading from mediocre speakers, please just buy these. They are worth every cent. Extremely way to set up as well. Mine worked right away after a restart. ... show more
