Plantronics is touting that its Marque M155 is its smallest and lightest Bluetooth headset it has made. At 7g, it certainly feels like it. The included documents seem to be a tad heavier than the headset itself. While the M155 is small, it still has enough charge for around 5 hours of talk time.
Pairing the Marque M155 is as simple as holding the main button on the headset until the light blinks and connecting your smartphone (or other Bluetooth device) to the headset. It will then prompt you that it has connected to the device.
Speaking of prompts, the M155 prompts you of its activities via voice. Switching the headset on, and a nice lady with a British accent will tell you that it has been switched on as well as tell you how much (in hours) battery it has left.
It will also tell you when it has connected to a device as well as when it has been switched off.
Although the packaging and even Plantronics themselves say that the M155 is compatible with Android and iOS devices, it will certainly work with other Bluetooth devices. What you don’t get is the downloadable app that is available in the iOS App Store and Android Market Place. The M155 will still work as a basic Bluetooth headset and even work as a music headset (although mono) with A2DP and hands-free answering.
When connected to an iOS device, a battery level indicator appears on the phone so that you will be able to visually monitor the battery life of the M155. You also have the option of downloading the Plantronics MyHeadset app from the Android Market Place or the iTunes App Store. The app itself is primarily for those new to Bluetooth headsets. It gives you a step-by-step on pairing the M155 to your device as well as explanations of the headset’s functions. For the more advanced user, it really isn’t a necessary download.
Those that I talked to using the M155 didn’t have a problem hearing my voice, although most of the time, I was using it in the relative isolation inside a car. I didn’t have that much of a problem hearing them once I got the right fit on my ear. More on that below.
One function that has been glossed over is that the Marque M155 can connect up to two devices at the same time. I was able to connect up to two smartphones at the same time where the primary phone (Phone 1) will have priority with A2DP functions such as listening to music or podcasts. With both devices connected, I was able to listen to my podcasts on Phone 1 and still answer calls on Phone 2. As I answered the call, the music automatically stopped on Phone 1 and after the call, the music continued without me having to reach and press play on the first phone. This allows for a truly hands free experience.
Now, the downsides. There really isn’t that much except for the silicon tip to secure the headset on the ear. The tip comes in three sizes, S, M, L. I get the idea of its design and how it theoretically works but maybe it’s just the shape of my ears but it doesn’t feel as secure as I want it to be and that the earpiece isn’t set right in to my ear. This means that the output from the headset tends to be drowned by the ambient noise of my environment.
While this seems a big problem, it really isn’t; as finding the right size for my ear and resetting the angle of the silicon tip enabled me to find the optimum fit for my ear.
Another problem, although more of a nitpick, is the volume button of the headset. While looks like a volume rocker, it really is a button that gradually gets louder when pressed and loops back to the softest when reaches its maximum volume.
While I wished that the Plantronics came with a power adaptor to charge the headset, it does come with a USB cable that is able to charge over any USB port. The cable itself has its own USB port to be able to piggyback on other USB charges to charge both the headset and another device.
At 1800 EUR, the Plantronics Marque M155 is a good deal. Being able to connect to more than one Bluetooth device is very convenient especially when you are occupied with more important activities such as driving.
