3SIXT Studio True Wireless Earbuds (review)
4.1Overall Score

Price (RRP): $129.95
Manufacturer: 3SIXT

At less than half the cost of Samsung’s ICONX or Apple’s AirPods, 3SIXT may just have the winner in the value stakes for its Studio True Wireless Earphones.

These cost $129.95 compared to the iconic Icon X at $299 (GadgetGuy review here and street price is closer to <$229) or the dorky Apple AirPods, at $229. But for $100 less its fine to overlook some minor imperfections.

GadgetGuy uses established paradigms to test and rate products. These are being tested as general-purpose wireless earbuds focused on music.

Out of the box 3SIXT True Wireless Earbuds

  • Studio True Wireless Earbuds
  • 6 x Gel tips (S, M, L) – these are Comply compatible, so replacements are easy
  • Power Bank Carry Case
  • User Guide
  • Micro USB Charge Cable

The first impression is that they are very Samsung Icon X like – an attractive grey and black in-ear canal earphone.

Pairing is a two-part process. First, they pair to each other wirelessly; then they pair via Bluetooth 4.2 to a smartphone, tablet, Windows or macOS device. In a week of use, they were flawless.

IP rating

These are IPx4 meaning water splashing against the enclosure from any direction for up to 10 minutes shall have no harmful effect. They are not suitable for swimming.

Bluetooth 4.2

Allows for multi-point connection – two devices and up to eight memorised devices. It also means it is future compatible with Internet of Things smart home devices.

It supports the standard A2DP codec – not apt/HD or LDAC hi-res codecs.

Battery

It recharges using the supplied cradle which houses a 500mA battery. Each bud is capable of three hours playback, and I tested that over three one-hour morning walks.

It recommends a minimum of a 5V/1A USB charger (not supplied) – it works fine on 2 and 3A chargers and the case recharge time decreases accordingly from about 90 minutes.

The case can provide about five recharges to the buds that have 50mAh batteries. Recharging is a little slow at around 1.5 hours.

How does it sound?

The usual disclaimer – select the right sized gel tip for the best, snug, in-ear canal fit. If you don’t two things will happen.

First, you won’t get the sound isolation and quality you expect and second, they might fall out if you are vigorously exercising.

And it all depends on content. For example, vocals are clear enough in Beach Boys including the subtle cymbals in the background. In Blues Brothers “Everybody needs somebody to love” you get the vocals and barely acceptable bass.
