[8125, K-JAM, P4300, MDA Vario General] Sleuth255:
So my HT820 moto headset arrived today and here's my promised comparison between them and my HP iPAQ FA303s. The testbed is my 8125 with the production Qtek v2.17 AKU 2 Rom. No customizations other than EdgeIcon were run and my device is overclocked to 240mhz. The A2DP patch dlls were manually installed and all registry changes were made by hand. I also installed Zoki's Cert cab so the dlls would execute properly.

First, let me say that on my 8125, TCPMP v0.72RC1 blows away WMP from a high fidelity and ease of use perspective. There's no comparison between the two. Unfortunately, TCPMP doesn't understand AVRCP but hopefully Picard may fix this. My comparison is therefore based on the two headsets' performance with TCPMP. I have equalizer mode on with all sliders except preamp set to their default midpoints. The preamp slider is set to about 60%. I am running 0 preamp boost from the audio menu.

The HT820 is a nice headset for sure. When it's direct connected with the included cord, the sound volume is noticibly lower however. Maximum volume is not enough IMO to use in this mode. Fidelity is pretty much the same in both wired and bluetooth mode too so I'll be leaving the cord at home. This headset easily switches between stereo headset and phone headset mode too. If I tap the left button while a song is playing, the microphone app appears and I can voice dial easily. In the phone app, the headset icon is active and it switches back to music mode when the phone is disconnected. This only works well with WMP btw because AVRCP is used to pause and resume the music when the headphones are in phone mode.

All in all, a great headset with the added bonus that it uses the same style charger jack (mini usb) so will work from the same charger as my 8125.

However, the fidelity of the FA303s are better IMO and they can get louder too because they sit closer to your ears, but that is balanced by the increased comfort of the Motos which are incredibly comfortable to wear. The motos fidelity is definitely a let down compared to the FA303s though and they distort a bit at high volume too.... sigh, there's no perfect solution here...

Bottom line:

The FA303s have much better fidelity and a higher max volume but aren't as comfortable and don't do phone headset mode.

The Motos switch well between phone and stereo headset mode but aren't as loud. Their fidelity is lower and they distort on the highs. Throw the cord away because max volume is dismal when used in this mode. I couldn 't detect a noticable hiss from either of these two headphones.

I'll be keeping the Motos because phone mode is important to me. On second thought, I'll be keeping both I think.

edit:

After sleeping on it then trying them both side by side again, I can easily say that there's a night and day difference between the fidelity of the two headsets. The motos are dull and buzzy on the highs while the HPs really kick the sound with crystal clear highs and bass that you can feel. Another thing I noticed was that when direct connected the motos lost the buzzy high notes. However this could have been due to the reduced volume. I'm actually beginning to believe I may have a defective headset here...

Final edit bottom line:

If you want true HiFi sound through a bluetooth stereo headset on your HTC Wizard, leave the motos on the shelf and go for the HPs. I just wish the OEM that makes the HPs would come out with a version that does Phone headset too....

btw: the Logitech bluetooth wireless mp3 headset and the HP FA303s are made by the same company. They're virtually identical except for the logo on the power button.
