    • What a nice speaker for my room!
Size: 3.5" Monitor BT Gen 2 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

    • Really great sound for a great and competitive price!
Size: 3.5" Monitor BT Gen 2 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

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

Great sound quality for the price, and it looks fantastic too. I’m definitely planning to pick up the subwoofer soon to finish the setup. The only reason I’m not giving it five stars is because there’s an occasional pop or crackle. It’s very minor and you barely notice it when music is playing, so I’m not sure if it’s an amp issue or maybe some kind of interference. Aside from that small hiccup, it’s a solid buy. You won’t be disappointed. ... show more

    • Great Little Speakers with Surprisingly Good Sound Separation!
Size: 3.5" Monitor BT Gen 2 Color: White
Bought these to enhance the sound coming from our ceiling-mounted TV on the back porch. Though you plug these into an outlet for power, they receive the sound signal wirelessly to good effect. Great sound, sufficient volume, and great instrumental separationing between the two speakers, a true stereo acoustic experience! These provide very decent sound, have proven very reliable, and they look stylishly elegant, and all for a lot less than a pair of Bose bookshelf speakers. Served my every need so, 5 stars baby! Great job! ... show more

    • Good Speakers - And the bluetooth "power saver" CAN be disabled!
Size: 3.5" Monitor BT Gen 2 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

Excellent sound but tiny pairing button in the back is inconvenient and hard to find. If the pairing button was put in front and larger with the on/off and volume knobs this would rate 6 stars.
