I hate statements like these. It's not true. Put on a recording with deep and solid bass, and you'll hear deep and solid bass. Maybe not to the point of something like the Hifiman HE400, but saying it's bass is anemic, or "Lacking vitality; listless and weak", is either a subjective opinion based on a basshead's distorted notion of what good bass is, or it's simply an objectively incorrect statement.
We could argue all day, but compare to 3 other headphones, Beyer 990, known as a bass monster, Grado SR80, considered a quite good headphone, and HD600, another 'classic'.
Yes, the 990 will have MORE bass because of it's 100-130hz bass hump, but another headphone without this emphasized bass is not anemic... Anyhow, I guess it's something people just will never agree on... I have the 990 and the Q701, yes, the 990 has more bass, and yes, it might sound more substantial, but saying the Q701's bass is anemic is ludicrous.
If the recording has very little bass, yes, you'll hear very little bass on the Q701, and you might hear what you consider a 'normal' amount of bass on the 990. Doesn't mean the Q701 lacks bass. As on a record with a lot of bass, you'll hear a lot of bass on the Q701, and you'll more than likely hear much more bass on the 990.
More bass is not better, and headphones which doesn't emphasize bass are not anemic...
