JBL Synchros S400BT
In-ear JBL J46BT now available to purchase, with over-ear JBL Synchros S400BT scheduled to hit the shelves next month

JBL – the American manufacturer owned by Harman International – has launched two new Bluetooth headphones in response to what it calls the "growing market demand for wireless features".

The company says its in-ear JBL J46BT and over-ear JBL Synchros S400BT headphones have been designed to combine high quality sound with the flexibility of wireless Bluetooth connectivity.

First to hit the shelves are the JBL J46BTs, a rare pair of in-ear Bluetooth headphones. Available now for £90, they boast a three-button remote control to adjust volume, play/pause music and answer phone calls. 

The buds come with Bluetooth 4.0 connectivity; advanced 6mm drivers; a frequency response of 20Hz to 18KHz; and three sizes of silicone ear tips designed to offer comfort and noise isolation. 

In addition, there are two sizes of sports cushions for greater stability. The rechargeable battery has a charge time of 2.5 hours, with the headphones offering a music playing time of five hours. They come in two colours.

More after the break

Meanwhile, the JBL Synchros S400BT are coming to the UK market in March for £250 with the JBL touch sensor control for "an ever simpler way of controlling the listening experience".

Built-in batteries offer 15 hours of playback via Bluetooth 3.0 technology, while you can also connect them using a cable for passive playback mode – even while the battery is recharging. 

The 40mm driver aims to provide clarity and hard-hitting bass, while echo-cancellation technology is used to provide "natural sounding" phone calls. They will be available in two colours.

They look nice, I've actually

They look nice, I've actually been considering getting the JBL J46BTs for doing running, skiing and other sports. However, what do you think, are they better Bluetooth headphones than the JayBird BlueBuds X Sport for these things? The JayBird BlueBuds are considered to be some of the best Bluetooth headphones for things like running at Headphons Unboxed which is a source I trust, but the JBL J46BTs do intrigue me a lot actually. Some advice would be appricated…
