Nice, a Monoprice Sendy Aiva.

Being listed at 299.99, how do think they they'll compare to the Sendy's? I'm really interested to see what opinions are when they start to roll in.

I mean, soundwise it will probably be similar like the other headphones using that driver. Sendy Aiva build quality will undoubtedly be better though.

I haven't heard the Sendy Aiva or the Blon B20, but I imagine they are all the same. The measurements I took are off of EARS using HPN compensation. They are very, very close to the Aiva measurements from others. There's a weird 900Hz cliff there that I wasn't able to get rid of with pad replacements, so not sure where that is coming from.

The first thing I noticed was that these are much heavier than specified. They're listed at 420 grams, but in reality, I measured these to be 523 grams w/o cables. It's otherwise built like a tank, and look great. I like the sound, its' good good flat bass and lower mid-range. There is a slight recessed upper mid-range, but I dont find it problematic for my tastes. The treble is sizzling! It's got a kick to it, that really brings pop and details out. It may become fatiguing at higher volume listening for me, but I don't generally listen that loudly.

Since these use a double-sided planar magnetic driver, they do leak like no other. They work well as a desktop speaker.

How does the sound signature compare to the Phantoms? Looking at your FR curve, they both seem to have recessed mids, but maybe the 570’s recessed region is even bigger. It looks like the 570 treble is more pronounced, and lacks the strange spikes of the Phantoms?

I think I will wait for the other Monoprice offerings, and lots of listener impressions... was disappointed when I jumped early on the 1060 bandwagon...

I find that the sendy drivers leak a hell of a lot less than open back modded m1060c and HE-560s. A LOT less.

The M570 is not as recessed as the Phantoms, even after all my modding. I actually dont mine the M570 at all. The treble is a little hot, but exciting. Many will probably enjoy that.

I have both the HE560 and the M570. The M570 is clearly a desktop speaker when not on your head, and the HE560 doesnt leak nearly as much.

Cool. Thanks for posting the graphs together - much clearer than me going by memory!! What are the mods you did to the Phantoms?

They look gorgeous, and I hope lots of people will enjoy them. But seems they will not match my sound signature preferences. I can hope the M1570 will get a lot closer!

Weird, the HF 580 and Aiva both leaked less than the HE 560 in my experience.

The advertisement for theses say "extended soundstage" is there anything special about the soundstage ?

 

[Flak]

Has anyone had a chance to listen to these? Would they be any kind of upgrade over the Massdrop HE4xx and/or unmodded H58x (I have both of these and K7xx)?

 

[forge457]

how much juice do they take? would they go well with then dac amp combo of the SMSL SU-8 Version 2 DAC & SMSL SP200 THX

AAA 888 Headphone Amp, plus is the Monoprice M570 better then the 1060,can the cable be upgraded to a periapt

,if so what kind , would they be a great step up from the m565?

oh has anyone got a chose music list to sample on the 570 ..im aways on the look out for something that can handle solar fields ,koan ,massive attack,an tool really well
