Comfortable. Premium feel. Good high-mids and highs.
Pricey. Weak bass response.
- Bottom Line
The LG Tone Infinim Bluetooth earphones offer solid sound quality, but they're a bit light on bass for the price.
The Infinim sit near the high end of LG's Tone series of wireless earphones, with a more premium build and notably better sound quality than the Tone Pro and Tone Ultra. The earphones also have a notably higher price tag, at $149.99 compared with $69.99 and $99.99. Audio performance is solid, but the Tone Infinim doesn't stand out amongst the similarly priced competition.

The Tone Infinim shares the same general design elements as the Tone Pro and Tone Ultra, with a slightly more solid and premium-feeling build available in black, pink, or silver. The neckband is a flexible length of plastic that curves like a horseshoe into a thicker arm on each end. It weighs just 1.8 ounces, a hair bulkier than the Pro and Ultra, but still very comfortable to wear.
The left arm holds a small power switch on its inner side, and a call answer/end button, flat volume slider, and micro USB port for charging face outward. A play/pause button and track forward/back switch face outward on the right arm. The pinhole microphone for making calls sits on the top side of the left arm.
The earpieces are cylinders with textured, gunmetal-colored tips shaped like bottle caps. They connect to their respective arms on the neckband through thin 10-inch wires. A button on each arm retracts the wires into the neckband, making each earpiece rest under a lip that completely covers the top of it.
Considering the price, the Infinim comes with few accessories. You get a USB cable for charging and two additional pairs of eartips in different sizes besides the pair that comes on the earphones. It's a wider selection than the Tone Pro and Tone Ultra (which only include two sets), but it still isn't much.
Battery life for music is estimated at up to 12 hours, depending on your volume levels.

While it pushes just a little harder than its less expensive siblings, the LG Tone Infinim shares the same lackluster bass response. The kick drum hits in our bass test track, The Knife's "Silent Shout," sound more like solid taps than heavy, head-shaking thumps even at maximum volume. There's no distortion at that level, though it occasionally sounds like it's getting close to crackling on certain notes. It's a more powerful sound than the aforementioned models, but only slightly.
The Tone Infinim's improved sound comes through more clearly in Fleetwood Mac's "The Chain." A greater reach into lower frequencies is apparent in the steady drumbeat on the track, which is more prominent and forceful than it is on the Tone Pro and Tone Ultra. It still isn't a particularly powerful thump, but it has more presence in the mix and presents a better balance against the vocals and guitars, which have a good sense of high-mid and high frequency finesse.
Thomas Dolby's "Hyperactive" also benefits from the slightly tweaked sound signature. On this track, the bass line gets more prominence than it does on the other Tone earphones, while the vocals stand properly in the forefront with plenty of presence and energy. It's a solid sound, even if the bass doesn't get quite enough low-end presence to keep up with the rest of the mix.
A Bit Too Pricey
The LG Tone Infinim is a solid performer, but at $150 it should sound better than just good. For the same price you can get the Beats BeatsX, which offer superior low-end and Apple's W1 wireless chip for better connectivity with iOS devices. Alternately, you could save some money and pick up the Jaybird X3 or JBL Reflect Mini BT, both of which also have stronger audio quality. The Tone Infinim would be more compelling at $100, but $150 is hard to swallow compared with the competition.
