Extend the connection distance between your iPhone mobile phone or computer headset by 1 meter&lt;br/&gt;&lt;br/&gt;The MUHSMF1M 4-Pole 3.5mm headset extension cable (1m) features a 3.5mm (1/8&quot; TRRS) audio connector on one end and a 3.5mm (1/8&quot; TRRS) audio connector on the other making it easy to extend the reach between your hands-free headset or headphones and your iPhone mobile phone or laptop computer.  &lt;br/&gt;&lt;br/&gt;To ensure long-lasting performance this high quality 3.5mm audio extension cable features molded PVC strain relief at each of the 1/8&quot; TRRS connectors which prevents the cable termination points from bending at sharp angles in turn reducing the risk of cable damage.&lt;br/&gt;&lt;br/&gt;Please note:&lt;br/&gt;&lt;br/&gt;To ensure proper hardware detection we recommend that the external headset be plugged into the adapter first before the adapter is connected to the computer or mobile device.&lt;br/&gt;&lt;br/&gt;Also in some circumstances when an extension cable is used with an in-line remote control equipped headset the remote control functions may not operate properly. This is due to the sensitivity of the remote control circuitry and does not indicate any defect in the cable.&lt;br/&gt;&lt;br/&gt;The StarTech.com Advantage&lt;br/&gt;&lt;br/&gt;- Molded strain relief prevents the cable from being bent at sharp angles at the TRRS connectors to minimize the stress at the plug termination point&lt;br/&gt;- Provides greater flexibility by enabling you to move more freely while working at your computer with VOIP applications (Skype chat programs)&lt;br/&gt;- Backed by StarTech.com lifetime warranty
