I bought one at FARHAD MANJOOMARCH 2 a few years ago End the promise to \"surround\" my home theater system with sound while watching Hollywood blockbusters- Or, more likely, a replay of \"law and order. \"But when I turn on the system, I see that in order to get the best audio, I also have to surround myself with speaker wires. The system includes five small speakers ( Two in front of the room, two in the back, one in the center) And a sofa. Shake the subwoofer. Each speaker and subwoofer needs to be connected to the central unit via a cable; That means I have to find an inconspicuous way to wrap around There are wires from my TV to every corner of my living room. It took me about a day to carefully rearrange the carpet and sofa in order to hide the wires, but even that wasn\'t entirely successful. Occasionally, the wire clutch peeks out and threatens to stumble over someone, or causes my Roomba robot vacuum cleaner to stop. I didn\'t bother to reconnect the system when I moved to my new home. The surround sound was sensational but not worth setting. Other people think so. \"70% of people buy houses \"The theater system never bothered to connect the rear speakers,\" said Ed de la Fuente, marketing manager at Aperion Audio . \". \"It\'s too much trouble running the wire. Until recently, there was no better way to advertise. Electronics companies have been manufacturing wireless speaker systems for years, but many are based on old radio technology that is vulnerable to interference from microwaves, cordless phones and other gadgets. The only way to get amazing audio is. . . through a wire. Advertising is changing. I \'ve been testing several wireless audio systems recently that promise me perfection ( Or at least fairly good) Electronic interference is much less sound than in the past. Some of them are for the living room, others are for the bedroom, and a fantastic system will deliver music for each room in your home. My Adventures in wireless audio have made my home full of speakers, but because they all require very little setup and because a lot of speakers can be hidden in invisible places, my home doesn\'t look messy at all ( Well, it\'s not because of the speaker wires anyway). The most basic wireless audio system I \'ve tried is the iA100, a $200 unit from iHome, perfect for playing music at your bedside, office, dorm or any small room. The IA100 is a trendy- You can connect to the clock radio of your iPhone, iPad or other smartphone via Bluetooth wireless standard. You can listen to music anytime your phone or music player is dozens of feet from ia100. The device won\'t win any audio enthusiasts ( It sounds a little small) But given its size, most people can accept its audio quality completely. I especially like the companion iPhone app for this system that lets you set the clock Radio alarm via mobile phone, which is much more convenient than fiddling with buttons on traditional alarm clocks. The IA100 has only one problem: it occasionally loses its wireless connection to my iPhone, and the only way to get it back is to go to the settings page of my phone and reconnect it. This is a small annoyance. At the other end of the price spectrum, you will find that Zikmu is a $1,600 wireless speaker designed by Philip Stark and manufactured by electronics company Parrot. Great Zikmu. Three speakers each. foot- High simple plastic plate standing on the circular base; My wife said it was like the obelisk at the beginning of the 2001: Space Odyssey that made the apes crazy. \"Like the iA100, Zikmu can play music stored on the phone via a Bluetooth connection, or by connecting to the home Wi-Fi network. Most of Zikmu sounds as good as it looks; The music played through the speakers is deep and full, and Zikmu is able to enjoy much louder than your neighbors. Nevertheless, I will not recommend them to enthusiasts. I noticed that this is because the music is skipped occasionally via Bluetooth connection ( Zikmu does have a physical iPod base and the music sounds perfect when I plug in my phone this way). Zikmu has other questions: the only way to connect it to my home theater system is with a wire. If you\'re looking for fully wireless speakers to watch a movie, these beautiful obelisk won\'t work for you. But the other two speaker systems do provide wireless sound to the home theater. These speakers use miniature transmitter devices that plug in a TV, DVD player, or other audio source; The transmitter makes a sound to both speakers and you can place it anywhere in the room. The first system, called Railtones, was made by a high-tech lighting company whose main business is. End of home lighting. This explains the shape of the rail speakers: they look like wall lights. In fact, the rail tone is designed for those who have already installed the designer lighting system at home. To set it up, connect each track speaker to the track- Lighting rails mounted on walls or ceilings; The speaker draws power from the track while extracting audio from the transmitter connected to the home theater. A set of two-track speakers and a transmitter cost about $500. I found that they made a respectful voice, but the real advantage of the railroad was the way they hid in your room. If you want your speakers to be invisible, there is no better place to place them in the middle and high of the bulb. In contrast, the Zona system manufactured by Aperion looks completely pedestrian- Black and rectangular, like hi- Since the 1970 s, there have been fi speakers on most home audio systems. However, look behind them and you\'ll notice something novel: There\'s no place to connect even if you want to connect the speaker wires. Instead, each speaker only needs to be plugged into a socket on the wall. Insert each one, then turn on the transmitter and the speakers make a wonderful, rich sound from your home theater. The price of two speakers and one transmitter is $500, Zona is expensive, but this is the perfect solution to send soundwithout wires — Behind a big room. But why is there only two speakers in the home theater system without wires? Nowadays, movies are programmed to generate separate audio channels for each of the five or even seven speakers. ( This allows filmmakers to play with some clever audio tricks like playing the sound of a squeaky door in the Speaker behind your right ear --a spine- Sting effect in horror film. ) Is it possible to get a home? Theater sound system with more than two wireless speakers? The short answer is: not now, but soon. On June, Aperion will release the Intimus 4 T Summit wireless audio system, which will transmit every sound of the latest blockbuster to five different speakers and a subwoofer. Mr. De la Fuente of Aperion called the new product a pioneer. \"I don\'t know how long it will last, but in the end, we\'ll see that most speakers don\'t have wires,\" he said. For now, however, mainstream buyers may not have access to fully wireless home theater: the Intimus 4 t summit will be sold for $2,499. However, wireless paradise is already here, excluding home theater. A company called Sonos has developed a series of interlocked Internet Designed to provide a connected audio component of music for your entire home. There are many different configurations to choose from, but the most direct device is the S5, a $399 speaker and amplifier. It\'s easy to set up: install software on your computer, plug the transmitter device into your wireless router, and then set up S5 anywhere in your home. The device is connected to your home wireless network and can access music on your computer from a variety of online services such as Pandora, Rhapsody, and Napster. But when you install a few 5S at home, the real magic starts. I put one in the bedroom, one in the living room and one in the study room. You can play the same song across the House or play different songs in each room; You can also control the volume individually or collectively. You can do all this with a company-specific touchscreen remote ($349) But you can also control the beast by using your PC, Mac, iPhone, iPad or Android phone. Best of all, a lot of people in your family can have a say in music. So when my wife sits in the living room and plays with something contemporary with her iPhone I think Kanye West One Sunday afternoon, I vetoed it in my bedroom and played a post-80 s music channel on my phone. Does this sound like a start to trouble? On the contrary. Music is everywhere, no wires. Believe me, it sounds beautiful.
