The Endurance Peak are available now.

With the increasing popularity of true wireless headphones, JBL is expanding its true wireless line up with four new models ranging in price from  $100 to $170 (no word on international pricing yet). Here's a quick look at the line up. Two of the earphones are available now and two will ship later this year.

The Peak is the newest addition to JBL's Endurance series line, which includes the Run, Sprint, Jump and Dive headphones. The Endurance Peak is a sports model with touch controls. I previously likened the Endurance Sprint (which has a wire between the buds) to a more affordable version of Beats Powerbeats3 headphones.

The UA True Wireless Flash retails for $170 and comes in one color: black.

JBL continues its partnership with Under Armour with the UA True Wireless Flash. I should be getting these in the next few weeks and will let you know how they sound, fit and perform as soon as I have a chance to play with them for a week. The TalkThru and AmbientAware feature are designed with runners and bikers in mind who want to let some sound in (such as traffic noise) for safety reasons.

The entry-level JBL Tune120TWS.

This is JBL's budget true wireless option that carries a list price of $100 (converts roughly to £80, AU$140). I handled it for a bit at CES and it was similar to other models at this price point (translation: it doesn't have a premium feel). The big question is how reliable the wireless connection will be and how good it sounds. I'll let you know as soon as I get my hands on a test sample this spring.

The Reflect Flow ships this summer for $150.

After getting a quick look at the Reflect Flow at CES, I'd say this may be the best of JBL's new true wireless earphones. Priced at $150 (roughly £120, AU$210), they're a little less expensive than the UA model and have similar features but stronger battery life.  They'll be available this summer.
