Yea, I reviewed it here: http://www.innerfidelity.com/content/sennheiser-ie-800-dynamic-ear-monitor . Beware that it has a lot of bass - more than the EarSonics and others.
Just needs one of these for the ALO. Using only the green end will solve the problem.
The SHE3595 is based on the 3580/3590, which are well-regarded. I quite like them. The XBA-1iP might be too long (in terms of housing length) to sleep with if you sleep in your side. Two more options you might consider (although they are not necessarily better than the Philips sound-wise) are the Brainwavz M5 (mic version) and the UE500vi.
Yes, I have the SE846. Unfortunately it's enormous and not comfortable for more than 45 mins at a time so I haven't used it much. Sound is good but hasn't impressed me quite enough to suffer through the pain of using them.
UE600 can be found in that budget oftentimes - good bet if he liked it. Another one to check out would be the Fidue A63 - it has more bass than the BA-based UE600 and the Monoprice, which makes the sound a little mainstream, but it's not bloated or muddy-sounding.
I've only tried the -Stage version of the V6, unfortunately.
Thank you, ljokerl, for your quick reply, I appreciate it. The Shure SE846's are pretty big, but comfort, and the audio it emits can be drastically improved if you invest in the Sensaphonics Custom Sleeves that are specifically made for the Shure SE846. I own them, and they feel like I am literally wearing nothing, because the sleeves are the highest quality silicone, and the full shell mold they create of your ear impressions goes as far as the second bend of the ear canal and covers/envelops the incisura, and concha (cymba and cavum) parts of the ear, resulting in the ultimate in comfort (more comfortable than acrylic because of its more forgiving and molding properties). I even have them in the Crystal Blue color, which won't discolor, unlike other clear (opaque) silicone sleeves (if your pH is such that will discolor the clear (opaque) color). I can't send a link without the message being immediately sent to moderators on here, (I'm still new on here and don't have post pic or link-to rights yet) so you can just google "Sensaphonics Custom Sleeves for SE846". I'm going to post a review of the Sensaphonics Custom Sleeves on the Shure SE846 Impressions Thread once I obtain rights to post pictures. Give the custom sleeves a try, I think that if you do invest in them, you'll enjoy the Shure SE846 that much more.
