the t.bone HD 515

These headphones are very good value and I'd recommend them with a couple of caveats:

They are a very "snug" fit and pressure on your ears/head might become uncomfortable during prolonged use. The earpiece material is comfortable and they cover my ears nicely without issue but that tight fit can be problematic, causing sweatiness around the ears and eventually slightly uncomfortable pressure on the sides of your head.

I only use mine for guitar practice at home. They are fine for that and sound good enough. I like the detachable lead jack and the lead itself is a decent length - both important features for me. They look and feel well made, the plastic and metal components are sturdy and will hopefully stand the test of time. For the price the quality is pretty good.

I'm no audiophile and don't need studio quality sounds and I'm sure those who do might not be so enamoured with cheaper cans but for most of us they're probably fine. Overall I'm happy with mine but if you are someone who is going to wear them for hours at a time, you might find them not to be the most comfortable choice.

For the price, it's difficult to fault these. But I'll give them a review as I would any headphone, no matter the price.

They are clearly based on the legendary 7506 as at a low price. They do not sound like them. Overall they lack bass, and I'm not talking about that over exaggerate bass that some people crave, just a realistic extension. They also lack sparkle in the high mids and highs.

Having said that, they do have a surprisingly wide sound scape and the individual instruments separate well in a mix.

Unlike the 7506, they have a straight cable that is removable/replaceable on a 3.5mm jack, thank you!

Otherwise the construction is pretty good. they look durable and will last with care. They are pretty comfortable too, probably better than the 7506 in that department. The headband is adjustable though a slidey grip with no detents ... no problem so far, but if it works loose over time, it might become one.

Overall, not a bad buy for the money if you just need some extra cans for your friends in the studio to get a respectable mix for tracking. Just don't expect them to be as good as the 7506 and you'll be fine.
