As we mentioned earlier, the Marque M155 has A2DP music streaming, voice alerts, and a free one-year subscription to the Vocalyst service. Vocalyst is essentially an automated phone service through which you can send e-mail and even tweets with just your voice. You can read more about Vocalyst in our review of the. Bear in mind that the basic Vocalyst service does require a payment of $2.49 monthly or $24.99 annually if you decide to stick with it. Vocalyst Pro (which enables you to send text messages via voice) costs $5.99 a month or $59.99 a year.
The Marque M155 also lets you answer calls by saying "Answer," which is handy if you're not able to press the button. Last but not least is a companion app that is currently available for both the Apple App Store and the Android Market called MyHeadset. It's essentially an app that teaches first-time users about the headset's features, like A2DP and Vocalyst. It also has a Sound Check app that lets you hear the sound quality of the room you're in.
We paired the Marque M155 with the Apple iPhone 4. Pairing was quite painless, but if you need even more help pairing your headset, the Marque M155 provides a voice-guided tutorial once you turn it on. It'll ask you if you have an iPhone or an Android handset, as it has tutorials tailored for those operating systems. Again, when paired with an iPhone, the smartphone shows a battery life indicator for the headset next to its own battery meter.
Listening to audio was a treat. Audio quality was rich, full, and sharp. It's certainly not as good as a pair of stereo headphones for music, but for listening to podcasts and audiobooks, it's just fine.
