Excellent Speakers for the Price
The Eris E4.5's arrived on-time and well packaged. These powered speakers are a great bit of kit. Nice weight to them, lovely design and easy to set up. Important: The "BT" model is Bluetooth, but the non BT is not. The sound reproduction is impressive for a speaker of their size. Deep undistorded bass and very bright high frequencies. Great for the amateur music producer, or as a basic room set up. Recommended!

Really nice budget speakers
Excellent small speakers which I’m using with Ableton Live and for the radio from my laptop. Lovely full sound for the small size. A bit bassy for me but there are tone controls on the back so just turned their down. £60 is a bargain. Snap em up

DAW and general use
I got these at the start of the year and waited a while to see how they worked out. For recording, they are excellent and I had no problems connecting to my PC. The 4.5" speakers have enough power for home use and can keep up with a guitar amp at home volumes. The cables for connecting the speakers were a bit short for my needs so I bought some 16 gauge wire and that was adequate. The slave speaker is 4 Ohms, 25 watt so up to 25 feet, 16 is fine. If you want longer, go with 14 gauge. The Bluetooth connection is simple and convenient. It turns these monitors into something very convenient and I wish more manufacturers would incorporate it. Being able to connect your phone or tablet is just fun. Something I think matters in a product in this category. No cables to listen to music on your phone, no messing about or booting up the computer. There are plenty of connections on the speaker and they will likely suit most home users. These are not high end studio monitors. For home use, this is actually quite a positive and part of the reason I wanted them. Professional studio monitors are extremely directional. These are, as all speakers, somewhat directional but they can fill a small room and be treated as a nice set of home stereo speakers. That may not suit pros but, if you are a pro, you will already know that and be looking for something specific. For music enthusiasts, creators and general home use, I think you'd be hard pressed to find a more compelling product. I do fancy the subwoofer but honestly, they sound good enough for what I use them for and I don't really need to shake the whole house. So, I'd definitely recommend them for home use and general listening. They would be good for a gamer that wants something better than your typical PC speakers, these really are a massive upgrade at a reasonable price. 4.5" is generally a good place for home use and that quality vs cost sweet spot. If you need something for the pro studio, these aren't that but you'd already know that if you did. More than enough for the vast majority though. They look good, sound good, work well, have Bluetooth, lots of common connections and all you need is some speaker wire if you want to separate them across a small room for a small stereo speaker system. They tick a lot of boxes and deserve to be praised.

Good desktop speakers, but not true monitors
Some of the reviews here suggest that Presonus have a quality control issue with the Eris 3.5. No such problems with mine, I'm happy to report. No hum, imperceptible hiss even with the volume turned right up, and both channels are equally loud. Connected by unbalanced RCA cables to my Focusrite Scarlett 2i4, the sound is clear with as much bass as you'd expect from such small woofers and plenty of treble. The midrange is good with reasonable amounts of detail. When used as desk-mounted near-field speakers, volume levels are very adequate. The EQ controls on the back of the left-hand (master) speaker are of limited use. I found little point in adjusting the bass control as turning it up just made the sound confused and flabby without actually making it go any deeper. If you want lots of deep bass from small speakers then adding a subwoofer is the only way to go. However, the rather splashy treble does benefit from being turned down a bit as these speakers are plenty bright. As for whether they are "monitors"; no, not really. They are decent-sounding desktop speakers at a fair price that are a huge improvement on cheap plastic ones, but they're too bright for reliable mixing and mastering, and would tend to create a a mix that would sound dull on other, more balanced speakers, and would also be quite hopeless for setting bass levels correctly. One last positive comment - there's no automatic turn-off after an inactive period as one sees with many powered speakers, so there's less risk of missing an alert because your speakers have decided to go into power-saving mode.

Best speakers ever
Gorgeous sound. The bass is amazing. I haven’t personally tried the Bluetooth but I have used them wired to my record player. The volume control is great, it’s a nice smooth Turing dial. They look sleek and beautiful. I can’t say they were super easy to set up as I got a little confused with connecting to the record player but I sorted it on my own eventually. They have a few different compatibility options which is great. And they’re a really nice size, not too big and bulky but great loud sound. Love them

Awesome sub, truly is a game changer if you produce your own music.
If you produce any thing with any sort of base, it doesn't matter how good your monitors are, you need a sub. I have giod monitors and great headphones, but my mixes came out muddy as hell anywhere I played the music that wasn't a decent set up. Adding a sub to my set up has let me mix in those lows soooo much better and it's made playing it on sub standard speakers sound so much better too. So it made the mixes sound better on a good setup but also made it sound better on a crap set up and got rid of a lot of muddyness. Having a sub truly is imperative to producing/mastering your own mixes. Looks great, functions as you would expect, plenty of drive, connects through Bluetooth (though I have it set up connected to my monitors through cable) size is as stated so nothing to worry about if you have a specific area you want to place it. Not remote controlled but honestly who needs that when you have the controls on the PC right Infront of you. The Bluetooth is pretty useless I feel unless your whole system is set up on bluetooth, as you need to either have Bluetooth or your audio interface playing, you can't have them both on at once unless you can find a work around.

Compact powerful speakers!
Have been eyeing these up for a while and finally glad I bought. Mainly for TV use and although I have to connect via headphone socket (no BT) the sound is amazing. With speakers set to 75% and tv at about 40%, the whole experience is brilliant, on a 4K fire stick and a PS4. Full volume is loud but very clear, gives some bass thumps when playing FPS games. Connection on them are analogue (balance and unbalanced 3.5mm) but should have went for BT version. I bought a BT add on module (from a well known auction site supplied from a country very far away) and while it worked fine, the BT module added latency that the fire stick couldn't compensate for. So I went back to analogue connection as that was working ok, just added a few extra cables to dangle around! Well worth the money. Very happy with the purchase.

Good sound whn played in, improved by an external pre-amp
Like many speakers and headphones, these speakers don't sound that good straight out of the box. So before you send them back to Amazon, play them in. When I was a member of Amazon Vine, I used to play-in headphones and earbuds for several hours before reviewing them. The speakers are active, but only the left speaker has the amplifier with a wired feed to the passive speaker on the right. They come with a 3.5mm TRS jack connected to right and left RCA plugs, 3.5mm TRS to 3.5mm TRS jacks, and bare-end twin cable to connect the right-hand speaker. The left-hand speaker front panel has an on/off switch, volume control, auxiliary input 3.5mm socket, and headphones 3.5mm output. At the rear and the connections, and small pots to adjust high and low audio response. As the speakers are near-field, they are intended to be heard within about a metre, so they are ideal for placing on a computer desk provided that for music, the tweeters are on the same level as your ears. I frequently use the speakers for Zoom and Teams online so I lay the speakers on their sides below the monitor. I put them upright in front of the monitor to listen to music. Whilst they sound reasonable with a connection to my Windows computers, it's improved by placing a pre-amp between the computer and the left speaker: in this case, a Fosi K5 pro.
