As we just did the Nokia Lumia 510 Review, now there is one more reason to recommend the Lumia 510. The phone launched in India as a budget friendly smartphone which works the Windows operating system, like its other Lumia siblings and other non-family counterparts, the Lumia 510 on its own is a good phone to buy. After packing the phone with great features that aptly suit a budget phone, Nokia is giving consumers one extra bonus, by way of a Sennheiser headset. Yes, apart from those bright colored earplugs Nokia offers with some of its devices, and which can also be directly bought from its store, Nokia has teamed up with the ever great Sennheiser, to boost audio quality and to give media lovers a real treat.These Sennheiser headsets valued at Rs 1700, will come absolutely free. Needless to say, Sennheiser offers unparalleled sound quality, and to get these free as part of the package receives a thumbs up at our end, and a salute to a good marketing tactic, one among many successful ones recently seen from Nokia. The Nokia Lumia has been given a price tag of Rs.10,499 and comes with 500MB of 2G/3G data free. The Nokia Lumia 510 smartphone runs on a 800 MHz mobile processor and has the Windows Phone 7.5 Refresh experience. Unlike most budget smatrphones this Nokia Lumia 510 smartphone is well pixelated for its 4 inch touchscreen display having 480 x 800 native resolution which roughly translates to a pixel density of 233 pixels per inch. This device comes with a 800 MHz Qualcomm Snapdragon S1 MSM7227A mobile processor backed by 256 MB RAM which work well to render smooth functionality, without hang ups, literally. At the back of the phone, a 5 megapixel is housed with f/2.4 aperture. Alongside this is the powerful LED flash. The camera produces good detail and contrast for a phone with its pricing. Voice calling is not an option on this phone for lack of a secondary front camera. Another let down is the fact that users will have to manage with the 4GB of internal storage as there is no slots for expansion via micro SD card.
