Pros
Pro Sustainable design
GrizzlyBuds are committed to reducing consumer waste. Each part can be individually replaced, meaning that no working parts need to be thrown away if just one piece breaks.
Pro Replacement parts are cheap
If one of the speakers goes out, it costs $14 to replace. If the cable goes out, it costs $11. Note that the assembled product is only $2 less than building it from parts.
Pro Good sound with excellent bass response
GrizzlyBuds' sound quality exceeds expectations for their price range.
Pro Extremely durable
Replaceable parts aside, GrizzlyBuds are built not to break in the first place. Earphone components are housed in aluminum cylinders, and the cable is reinforced with kevlar.
Pro 4ft cord
Cord is long enough for all uses.
Pro Clear Balanced Sound
Crisp and clear sound. Quite good for earbuds of this size.
Pro Warranty supported after over a decade and a half
There are tons of stories from customers that talk about how they supported their warranty after decades with no receipt, at only the cost of shipping and handling. Koss really means it when they say lifetime warranty.
Cons
Con Sketchy company
These originally appeared on Kickstarter as "IRONBuds", for which the company never delivered on their promised product. What they did deliver suffered from poor construction quality, and looks exactly like what is pictured here. The custom components that allow the parts to be swappable might have more value if they could be sourced from other companies or were held together with enough glue to keep them from falling apart in the first place.
Con No option for controls or mic
Despite a replaceable cable, GrizzlyBuds does not offer anything beyond basic headphone function.
