Update: Changing to 4 stars, as I am no longer trying to use these for a commute. They are very comfortable when wearing all day, and have held up very well since purchase. Definitely worth the $75.
These were purchased to replace a pair of ATH-M40X which broke due to a design flaw in the ATH-M series. I was looking for a nice solid closed back design that offered good noise block out. These are not them, but do sound very nice.
The Good: these are a nice set of headphones, comfortable to wear, and in a quiet location are OK. They are good at giving a degree of warmth to acoustic Guitar, Cello and String instruments, as well as vocals. The sound stage is good, but not as wide as open back headphones. The accuracy is good as well, although they tend to be a little accentuated on the bass. I especially enjoy using them to listen to orchestral, dub and Reggae. Compared to the ATH-M40x that these replaced, they are not as accurate. The M40x is more of a studio monitor, and adds less coloration to the sound.
The bad: As initially stated, I was looking for a replacement for my ATH-M40x headphones, a closed back design that really does block a lot of the outside noise. The Purple Heart E-MU headphones do not block as much of the outside sound. For closed back headphones these are really terrible at blocking outside sounds, and feel more like a semi-closed back design. If this were the only issue, then I could increase the volume and compensate.
What really stands out is that certain loud external frequencies appear to resonate within the headphones itself. I noticed this while commuting on the DC Metro, certain external train squeals/sounds became outright painful and louder than if I wasn't wearing the phones.
With many of us using Zoom, Teams, or other video chat and remote work over the past year, I find that I am wearing these a LOT. These have been my go-to general purpose headphones due to their lighter weight and comfort. Also, the purple heart and plain design do not detract a lot when in Zoom meetings. The fact that they are not as sound blocking as others also does not lead to strange voice effects when speaking in Zoom meetings.
Previously I recommended the Thinksound ON2s, which were great headphones. I am not sure what happened with Thinksound, but currently the only available options for Thinksound are their IEMs, with a Coming Soon for a replacement to the ON2s.
For $75 ,these are a great set of headphones, except for commuting or listening in noisy spaces.
Would recommend to a friend.
