I'm fresh off a pair of Sennheiser IE80s. They just don't do it for me without an amp and EQ, and even with the amp they're only ok. I tried out the GR07's, they're pretty muddy by comparison. I'm really interested in finding a loud pair of bluetooth headphones with a clear signature. To be honest, I picked up a pair of $30 SoundPEATs, some knockoff, no-name made in China bluetooth in-ears and they sound very similar to the IE80s, albeit about 2db quieter and clipping on the low end at full volume, but the sub bass packs on just about the same. I'm really, really disappointed in the IE80s. I'm going to return them, and I'm looking at the Shure SE846's. These are a whole $800 more than the IE80s. Is that how much getting an improvement with in-ear's costs? There has to be something better. I'm reaching out for help, guys. Help me out.
