Just purchased a backup set of Shure SE846 inear phones. I 've used them for some years as my monitors at live gigs to hear my Roland TD50KV pro Drum Kit mixed in with the rest of the band ( wwwfirestarinfo.co.uk). They are the best in ear monitors I have come across if you are looking for a seriously good set of in ear monitors and have the funds to spend. I especially like them for the lower bass end frequencies. When I hit the bass drum or floor tom you get all the low end you would expect from a studio miked up drum kit , as well as a full midrange sound and a nice clear crisp top end when hitting the cymbals, this is using the 846's with the blue coloured filters in them. The Black filters give a more warmer muffled tone to the sound ( Good for bass guitar?) where as the white filters keep everything that bit thinner and crisper probably better for vocals? As with all in ears they do require regular cleaning as ear wax can build up and change the sound quite a bit. I would recommend using the little pink tooth cleaning brushes you can buy for this. You may eventually need a new set of plug in leads, they can eventually wear but they are easily replaceable. Make sure you but original Shure ones. The cheaper rip off makes can easily damage the tiny pin connectors in the earbuds and as these earphones are very expensive, bite the bullet and get the proper Shure replacement leads to protect your investment. The 846's easily sound as good if not better than a high end set of over the ear headphones, but far less visible in a live gig environment. What's not to like
