Sound:
Accurate and flat sound which is what i was hoping for, if you have a studio or home studio you know that is very important. The 4,5 inch speaker size doesn't compromise the bass, you cannot expect huge bass like bigger speaker but the sound is decent.
I think the best win of these monitors are the mids, very precise.
I have the speaker for some time now and i can tell that they start to sound at 100% with about 80/100 hours of use.
Construction:
Very good construction, does not feel cheap. I like the fact that they have a sound volume knob at the front, its a win for me.
Last considerations:
Best monitors i have experienced for small/home recording studio. They have everything i need. If you need a set of monitors on a budget but still want quality i think these are the monitors your are seeking, i am not telling lies here, you cannot expect at this price point high end quality sound, for really, but at this price point you wont get anything better i think.
If broken or stolen i think i would go for the Eris 5 just to have a little more bass response, as a matter of personal taste
