Sennheiser HD 408 is a mid priced headphones but packed with minimal features. And thats understandable. The headphones can be bought for ₹1,500 from a wholesale dealer but the price might soar up if you buy from a local shop. Design Just like any headphones, these headphones also cover the head. It has a plastic build. On the top of the headphone, we have the company's name. There is cushion on top and for the ears. The cushion is pathetic at longevity and thats simply because of its poor quality. Due to sweat, these cushions start wearing off. Though the cushions are of poor quality, they don't hurt the ears or head. The build quality of the headphone is poor. Adjusting the headphone to fit your head is simple but again it can easily break if you try to mess around with it. The auxiliary cable is quite long but the 3.5mm headphone jack covering is quite weak. So there can be high chances of the wire getting damaged. Features Frequency Response - 25Hz to 21,000Hz Impedance - 32Ω Sound Pressure Level - 114dB measured at 1KHz and 1V (RMS) Neodymium Magnets Performance The Sennheiser HD 408 is a headphone which works like a charm on the iOS devices but the performance degrades on Android powered smartphones. The music output is really good. Its loud and clear. A good thing about these headphones is that they can be worn for hours without getting pain in ears or headaches. However as these headphones don't cover the ears properly, noise cancellation is poor. Due to this the person, near you can easily hear what you are listening too. It does not have any additional noise cancellation functionality. Due to the inbuilt mic, it is possible for making voice calls and also use it for gaming. Due to the Neodymium magnets, the headphones provides good bass to sounds. The bass is heavy and many a times takes away the nuance from vocals. Verdict Pros - Good Output, Comfort, Bass Cons - Build Quality, Noise Cancellation, Overbearing Bass Conclusion - Well i think these headphones are good for music listening and gaming purposes. Though it has a poor build quality, a user can still go for it. It is a good option for budget headphones.

Networking Switch is a awesome device, if you want to connect multiple computers to each other, thereby creating your own LAN Network. After this file transfers and chatting between all these computers becomes a piece of cake. Requirements Networking Switch. A basic switch of ₹300 to ₹600 should do the job. I am using D-Link 10/100Mbps 5 Ethernet Port Switch. Few computers. Be it Mac OS X, Windows or Linux. Ethernet cables. One for each computer. A Fast Ethernet cable (CAT5 and Untwisted pair) should be good enough. Applications like IPMessenger or Dukto. Both are cross platform softwares. Procedure Read the instructions and then see the video for a better understanding. Connect the Networking Switch to a power supply and Turn it on. Connect all the computers you want on the LAN Network to the switch via Ethernet cables. Now download an application like IPMessenger or Dukto. Both are cross platform softwares. However IPMessenger doesn't work well with linux, so I would suggest Dukto. Once you have installed the application on all your computers, the next step is the IP Configuration. This is the most important step. All computers will get an IP in sequential order. Turn off the Wi-fi if it is ON. The PC connected to port 1 on the Networking Switch will get an IP - 10.0.0.1, Router/Gateway - 255.255.255.0, DNS - 10.0.0.10 The PC connected to port 2 on the Networking Switch will get an IP - 10.0.0.2, Router/Gateway - 255.255.255.0, DNS - 10.0.0.10 The PC connected to port 3 on the Networking Switch will get an IP - 10.0.0.3, Router/Gateway - 255.255.255.0, DNS - 10.0.0.10 Do this till the IP Configuration is complete on all the computers. Now open IPMessenger/Dukto. All the computers connected to the switch should show up. Now go ahead and do some file transfers and chatting on your own LAN Network.
