This headset must be used with the HEARO 999 base transmitter ot other suitable AKG IVA transmitter. I own the AKG K301 XTRA, K601, and Beyerdynamic DT880. The sound quality is overall superior to the K301 XTRA without the midbass hump similar to a Grado SR225. The bass extends deeper than the K301 XTRA. The treble is not as prominent as the DT880 but has a more present and clear midrange similar to the K601. The affinity for female vocals, or any vocals for that matter, is evident just like all premium AKG headphones. Midrange detail is outstanding. Being a semi-open design like the DT880, the bass quality is more similar to that headphone than the K601. Think of the HEARO 999 as a cross between the DT880 and the K601, and you will have a good idea of how it sounds. The reception is in the digital domain and digital to analog conversion is done in the headphone. The reception is very clear and noise free, very similar to a hardwired headphone. This is a true reference grade dynamic headset and has numerous professional users. After getting accustomed to the mobility it allows, my hardwired headsets are getting less use these days. I have a detached garage, and my reception in the garage is good. Since there is a top quality DAC in the headset, battery consumption is high and the absolute max time per charge is 5 hours on fresh NiMH batteries. You need a spare headset if you own the standard single-headset unit and depend on the 999 as a tool. Recharge is accomplished before the unit in use goes dead. I bought the package with dual headsets and saved $100. Do not think this is like those cheap wireless headphones for casual users that "the other brand" is famous for providing. Pro quality all the way and it fits in with AKG's other wireless technology for the pro user.

The headset is somewhat heavy and it is not for iPod or Walkman use unless you hook them into the transmitter. Portability in this instance means the ability to roam around an installed transmitter base. Coverage is sufficient for the average house with the 999 transmitter. There are separate volume and balance controls along with the three-position transmitter channel selector on the right can, and the power switch and charger jack are on the left can. The headphone DAC is a 20-bit processor. The transmitter uses 24-bit processing for the surround modes.
