I've been using Timber Wolf Lobo's for over 15 years. They can be toggled between normal audio and a mode that amplifies the weak signals, attenuates the loud signals and lowers the frequency of the audio, but it gets way too hot here in the summer to wear full size headphones. I've had other headphones that were good, Grey Ghost, Troy Pro and others, but I don't hear as well as I did when I was younger and the Lobo's are better suited to my hearing. When the temps get above 70 degrees I use earbuds. To have the audio sound right for my hearing I have to use Koss earbuds with the Barons, CS-5ZX, Garretts and 1266 and Sony with the Golden ÁMax.
