Overall, I’d say they’re a good value for the price. Certainly not perfect, but not bad; they’re better than the Plantronics Pulsar 260’s, for example; pairing was easy enough with these. More to come later after I’ve had more time to use these; their biggest weakness, IMO, is the one-button interface, and the relatively bad handling of switching from phone to A2DP and back, contrasting with the Motorola HT820’s.

-They’re LOUD. Much louder than my Motorola HT820’s are; they’re also rather ‘flat’ in their sound, at least compared to the HT820’s which emphasized the voice frequencies more. At maximum volume, the Motorolas sometimes could STILL be drowned out; the HDBT-700’s are better in this respect.

- I hate the foam earpieces. I’d rather the leatherrette padding of the Motorola HT820’s. These… I don’t know what’ll happen when they wear out. I’ll email Helium Digital about them.

- Sound quality’s okay - nothing to write home about, but the sound is loud and fairly crisp. They won’t beat even a $99 set of Ultimate Ears super.fi 3’s.

- Reception’s the weak point - walking away from the Axim x51v and going into the bathroom, I could hear a lot more interference than I could with the HT820’s. Also, I’ve had these get choppy and skip a bit where the Motorolas usually did okay. Not sure if this is a one-time thing, or if it’ll become recurring.

- They don’t handle the transition from calls to music and back as well as the HT820’s - having one button seems to hurt them, and I’ve found that when trying to switch from phone and back, I lost all control and sound from the A2DP profile. This is a great contrast to the Motorola HT820, where I didn’t have this issue - whether it’s a better implementation on the HT820’s or because there were two buttons on the HT820, I’m uncertain - but I had to manually disconnect and reconnect either by turning the headset off and on, or by doing it from within the Axim’s BT management system at least twice, when I was testing the automatic transition.

- They don’t pause music in PocketPlayer 3.0 when taking a call. The documentation says they do this, but this is probably just in WMP; I haven’t tested that yet.

- They’re extremely light; much lighter than the HT820’s (50 grams versus 98 grams), but they don’t seem to ‘fit’ as well even though I have a regular-sized head, due to the way the earhooks don’t QUITE grip the side of the head as much as the HT820 did, especially with the way those earpieces covered more of the ear. On the other hand, I don’t suffer Princess Leia syndrome wearing these unlike the HT820’s; they’re the size of regular headphones, and they’re very easy to wear otherwise (the HT820’s were a bit fatiguing due to the grip on the ears, and the way the leatherette caused the ears to sweat in warm weather)

- The controls could be a bit easier to use - there’s no real tactile feedback for the back/forward, or at least not as much as the up/down buttons. They also beep when switching tracks using the back/forward buttons, unlike the Motorola.

- I miss the ability to turn off the LED. The HT820’s best feature was this, on top of the 2.5mm jack.

- Battery life’s definitely shorter than the HT820’s, by about 4-5 hours. The Motorola HT820’s really DO last 10-12 hours on playback. However, the sound quallty with the HT820’s during calls was worse than the HDBT-700’s; BT 2.0 seems to make a difference after all, at least with my BT 2.0 capable phone.
