This small yet wonderful product from Nokia is good.
Though its battery life is very short of 5hrs.
If you use it only when you receive a phone call then the battery lasts for more than two to three days.
And its price too is negotiable.
I got mine for Rs.904 whereas in outside Market it was available for Rs.1250/-

I placed an order for this headset a few days ago and received it today. I liked it as soon as I opened the box. It's very neat and compact, and yet fits perfectly in your ear (I have small ears) thanks to the adjustable earhook. Pairing this with my Nokia 5800 Express Music was a breeze.
Settings > Connectivity > Bluetooth > turn it "On" > go to the 'Paired devices' tab > select 'New paired device' and it'll find the headset Nokia BH-105.
Once synced up, it was good to go. Answering and endi...

It is a good product with elegant design and good performance.
Delivery of flipkart was also wonderful and they delivered me the product right on time I had asked them for...

This has a great form factor and super comfortable to use. I lost it somehow and when I wanted to buy another one, didn't find it. Guess they have discontinued it. If this was available I would certainly advocate buying this and also buy another one for myself. I use BH-108 now but since its a bit longer, its form factor is not as sturdy. Adjustable ear hook is also quite innovative. If you loose the clip only, it should still serve the purpose. Easy to switch from left to right.

I have been using this from the past 6 months but i have nt faced any problems till now.
Pros-
1)Rough and tough
2)Battery backup is awesome
3)even u can listen music by connecting it to any nokia mobile
Cons-
1)u need to reset it every time when u connect it to a new mobile
2)Voice clarity is good but u need to speak a little a little louder than u usually speak on ur mobile .If ur planning to use it while driving then giv it a thought
3)Im not at all satisfied with its looks .Samsung steal...

Sound clarity is good.
Battery backup is about 7 to 8 hours.
Simple and interesting operation with instructions.
Nice pairing.
Nice design.
Can be used on both ears-removable earhook.
Worth buying for its price.

If u want to waste ur money then only u buy this. These are very losse in ears.Not enough sound to hear songs in public place.Also very bad connectivity.These are connect only with some of the nokia mobiles.

VERY BAD
