We chose to be patient and charge both the headset and recharging case. It took more than 5 hours for everything to come to full charge which was actually longer than I was expecting, but since this was the first charge, it is somewhat understandable. After the charging was complete, we turned on the headset and the Discovery 975 was immediately recognized by our mobile devices. The pairing process took no more than 30 seconds.
Let me just cut to the chase and tell you that the Plantronics Discovery 975 is one of the best Bluetooth headsets that we have used. Ever. The headset’s gel earpiece design is one of a kind and can be worn for hours on end without a hint of causing ear fatigue. The buttons on the 975, while small, were very functional and you get used to the size after only a short time of use.
The sound quality of the headset was superb. We thought it couldn’t get much better than the older Discovery 925, but doing a ear-to-ear comparison, we think the 975 is slightly louder. It could just be that the newer 975 has a slightly upgraded DSP.
When talking to others, your party will hear you loud and clear. Even in a loud room or environment, the Plantronics Audio IQ2 DSP and dual microphone works together to filter out unwanted noise from your conversation. Even the mighty Jawbone 2 takes a back seat to Plantronic’s newest headpiece (although I’m certain this will be a matter of future debate). The Discovery 975 handles almost every noisy situation with ease. The only time it struggled was when we dropped the car windows doing 60+ miles per hour. The party on the other end could still hear our voice, but they heard a tremendous amount of wind noise. Many of the Bluetooth headsets that we test can’t even be heard with the radio and Air Conditioning on let alone the windows wide open. This is always the hardest test of a Bluetooth headset and the Plantronics Discovery 975 performed superbly.
