LG is doubling down on wireless neckband earbuds with its product refreshes of the LG Tone line. The LG Tone Flex XL7 is a premium headset at a fair price. The retractable earbuds are practical and dedicated Google Assistant is conveniently placed. If you’re in the market for wireless earbuds with great battery life and sound quality, you can’t go wrong with these.

Who is the LG Tone Flex XL7 for?

  • People who value sound quality and convenience will be intrigued by the Tone Flex XL7 headset. While it only supports the AAC high-quality Bluetooth codec, it upsamples low-quality audio files with its 32-bit DAC and uses Meridian Audio tuning.
  • True wireless-averse listeners have probably considered a whole slew of standard wireless earbuds. This headset is a great option because of its convenient features like retractable earbuds, long battery life, and Google Assistant integration.

What’s it like to use the LG Tone Flex XL7?

The neckband is flexible yet resilient.

As the name denotes, the neckband is flexible which makes it easy to stow the headset in a side pocket or purse. The rubberized segment has a modest stippled texture. This creates just enough friction against the back of the neck to keep the band in place. The left side of the neckband houses a few buttons for powering the headset on and making playback and volume changes. You’ll find the USB-C input on this side, too.

The opposite side has a single button for Google Assistant access. Pressing it prompts a female British voice to read your notifications aloud. If you want to make a command, hold the same button down for the duration of your command or question. Once you’re done speaking, release the button and Google Assistant will provide a response.

The Google Assistant button sits independently from the playback controls, making it easy to find and use.

Retractable earbuds are a neat design but these ones needed help along the way. The ‘buds stopped withdrawing just a few centimeters from the neckband caps. I had to manually push the earbuds back into place. It’s not a huge deal. Yet it’s annoying seeing as this same mechanism works flawlessly on other LG headsets.

LG only provides large and small ear tips, so you may benefit from investing in a third-party pair.

This stands as yet another headset without angled earbud nozzles, which makes finding a proper seal more difficult than it would be otherwise. The headset lacks any water-resistance or official IP rating. However, it does have a nifty feature of vibrating during incoming calls. It doesn’t vibrate for general notifications though, which I found to be a shame.

How long does the battery last?

The headset affords over 10 hours of playback on a single charge.

Battery life is considerable. Our testing yielded 10 hours, 22 minutes of playback upon subjecting the earbuds to a constant 75dB SPL output. This exceeds LG’s listed eight-hour duration, and when the headset dies, you can quick charge it with the included USB-C cable. Just 10 minutes provides three hours of listening, which is the same as what the Tone Style SL6s grants. Battery longevity and fast charging are two marked highlights of the LG Tone Flex XL7.

Bluetooth codec support

Just like the other headsets in the LG Tone line, the LG Tone Flex XL7 operates via Bluetooth 5.0 firmware with a 10-meter wireless range. Similarly, you’re limited to AAC for high-quality wireless streaming. This is to the benefit of iPhone users; however, AAC’s performance on Android devices is volatile. It seems a shortsighted mistake to forgo aptX support with a headset equipped with Meridian Audio technology and 32-bit upscaling capabilities.

Multiconnect functionality is included. You can connect to two devices simultaneously and alternate between the two by pausing playback on one and playing content on the other.

What do the LG Tone Flex XL7 sound like?

LG teamed up with Meridian Audio to tune the LG Tone Flex XL7 and audio quality is significantly clearer than the Tone Style SL5 and SL6s earbuds. This is in part due to the 32-bit DAC. While 32kbps is overkill, the technology upscales low-quality audio files, emulating high-res ones. If a file is notably low-quality, you may be able to perceive a palpable difference.

This headset has a fairly neutral response across the most audible portion of the frequency range. See how the green line neatly follows the red dotted line in the frequency response chart? That means those notes are accurately reproduced with minimal emphasis or attenuation. This serves those with eclectic taste as nearly all music will sound good with the Tone Flex XL7.

The LG Tone Style SL5 (left) and LG Tone Style SL6s (right) are both more affordable than the XL7 but reproduce less clear audio.

The earbuds isolate you from high-pitched sounds, but low noises like neighboring traffic remain audible. If you’re unable to get a proper seal, you’re bound to encounter auditory masking. This is when a louder sound makes it hard to discern a quieter one. See, our brains have limited processing power and can’t equally perceive limitless stimuli. It may be worth the extra few bucks to get a pair of memory foam ear tips. These will filter out external noise and optimize low-end reproduction.

Lows, mids, and highs

Jimmi Charles Moody’s song Happy Song opens with an F-G-B piano chord progression, which is accompanied by a lone whistle pattern and finger snaps. The whistling remains distinct from the lower piano chords. This surprised me seeing as some attenuation occurs from 2-7kHz, where we’d expect to find the harmonic resonances of a person whistling. That said, snapping is hard to identify in the intro and verses because Moody’s low voice and the piano chords’ fundamental frequencies overlap.

I enjoyed the sub-bass attenuation for this song because the bass guitar’s presence is prominent as is, a consequence of how the song was mixed. However, with the slight de-emphasis, it’s still a staple of the song but doesn’t run the risk of masking the cymbal hits which enter during the chorus or continuous whistling.

Is the LG Tone Flex XL7’s mic good for phone calls?

Microphone quality is significantly better than LG’s other Tone earbuds (LG Tone Flex SL5 and Tone Flex SL6s).

The microphone is significantly better than our previously reviewed LG wireless neckband earbuds. When limiting the mic’s response to the human voice band, we see that audio reproduction is fairly even across the board. Whether you have a high or low-pitched voice, the Tone Flex XL7 will make you sound as you do in real life. Clarity, however, is subject to change depending on how much you’re moving. Anytime I was talking and walking, the person on the other line could hear the microphones rustle against my clothing.

Should you buy the LG Tone Flex XL7?

Yes, the LG Tone Flex XL7 is the best headset between the Tone Style models. These are great for anyone who wants a pair of Google Assistant-integrated earbuds with reliable connection quality and accurate sound quality. Again, the lack of aptX support seems a shortsighted decision, but it’s no secret that the best audio quality is experienced through wired listening anyway.

If you like the LG Tone Flex XL7 but feel it may be a bit out of your price range. The LG Tone Style SL5 boasts a similar design sans-Google Assistant integration. Interestingly, the retractable earbud mechanism works more effectively on the cheaper model than this one. You can also abandon LG altogether as we’ve compiled a list of the best wireless neckband earbuds for those who aren’t yet ready to dive into true wireless picks.
