Look, we get it: Bluetooth headphones are convenient. Popular models like Apple’s AirPods are for all intents and purposes the K-cup coffee machines of audio. Just like those liquid sadness brewers, Bluetooth offers a disappointing, expensive facsimile of the real deal — but many enjoy it all the same.
Testing done for our sister site SoundGuys confirmed it’ll get you 90 percent of the way there — but not everybody is willing to accept the excuses behind ditching the headphone jack. Since USB Type-C headphones aren’t where they need to be, we have to examine the consumer audio technology’s performance in a world where the headphonejack is disappearing.
Bluetooth is extremely convenient, but at a cost.
The findings
A more in-depth description of the testing process and findings can be found here, but here are the broad strokes:
Every single Bluetooth codec has measurable quality issues, though not all significant.
Not a single codec or set of Bluetooth headphones available can meet wired signal quality.
Bluetooth audio has come a long way since its noisy beginnings, but it’s still not ready to replace the headphone jack. However, most people won’t be able to hear the difference if they’re older than 24, have some form of noise-induced hearing loss, or are in the presence of outside noise. For this reason, Bluetooth headphones are best for those commuting, or in noisy situations. If you’re listening primarily at home — or in a quiet area — get a set of wired headphones.
Also read: AAC has limited bandwidth, AirPods not ideal on Android
By using an aggressive psychoacoustic model of compression like MP3 compression, AAC seeks to cut data where you wouldn’t normally be able to hear it anyway, but it’s sometimes a little too aggressive.
AirPods may be trendy, but they have significant sound quality problems.
AAC has some advantages when it comes to latency, but we recommend avoiding this on Android phones if you care about audio quality. SoundGuys found high levels of noise, and lower than average frequency cutoffs — both unacceptable to audiophiles and younger listeners. Though the sound isn’t as bad as some may say, the shortcomings are noticeable to the human ear at normal listening volumes. In this light, wireless earbuds using AAC like the Apple AirPodsaren’t ideal for Android phone use.
Pay close attention to what codec your true wireless earbuds use, as well.
The noise for Android devices near 100Hz will audibly affect voice sounds, music.
Unlike with other codecs, AAC test signals from Android phones like the Huawei P20 Pro, LG V30, and Samsung Galaxy Note 8 all vary wildly. Though we can’t definitively say why each Android device seems to handle AAC encoding differently, we suspect some of the power saving features baked into the Android ecosystem’s varying hardware affect audio playback. Nowhere is this more apparent than Huawei’s power-sipping P20 Pro, which seems to cut out at around 14.25kHz. Our best guess is Android phones differ in how they handle task scheduling in the CPU, which has consequences for battery life and also fixes audio skipping problems with Bluetooth. AAC doesn’t hit the maximum range of audibility in any of the phones tested.
Related reading: Lossless audio only exists with LDAC 990kbps, but only sorta
LDAC is the only codec that truly attempts the hi-res thing, but it has perplexing issues with common phones. The bitrate defaults differ wildly from model to model. The Samsung Galaxy Note 8 and LG V30 both default to 660kbps, and the Google Pixel 3 defaults to the lesser 330kbps. However, you can change this in developer settings.
The new Sony WH-1000XM3 uses LDAC as its main Bluetooth codec, but you might not be getting the best they have to offer.
Despite big promises from Bluetooth’s only Hi-res codec, the standard doesn’t really deliver, and it falls short with its basic 330kbps setting. Both the 660kbps and 990kbps connections offer decent quality, but the 330kbps setting has a lot of noise, and a comparatively poor frequency response with higher-def content — you probably won’t hear it, though. We recommend using 660kbps as a good middle ground between quality and connection quality.
Pocket-to-ear signal strength hovers around -45dB, but can vary when your arms or other objects get in the way.
See also: Most of Bluetooth’s issues are inaudible to older listeners
If you’re over the age of 24, Bluetooth headphones are more than likely good enough for you. Most people older than that cannot hear the audible effects of Bluetooth — outside of AAC’s shortcomings, and a certain level of noise.
Blue: LDAC 990kbps. Yellow: LG V30+ Hi-Res output. Data collected by Robert Triggs.
Every single Bluetooth codec out there exhibits a higher level of noise than wired audio, though only AAC, SBC, and LDAC 330kbps exhibit audible noise. Where wired audio can handle CD audio and 24-bit music, Bluetooth headphones simply can’t, though 24-bit is dramatic overkill anyways. If you like your music loud, Bluetooth will be noisier than wired listening, depending on how high you crank it.
More: aptX and aptX HD get close to CD-quality, but not quite as advertised
Of the tested codecs we met, aptX and aptX HD fared the best out of all our candidates. While that may seem strange to say, on the whole their results were right where they needed to stand in for a wire for commuters and listeners over 40. You’ll really only run into issues at high volumes (more than 90dB), so while aptX can’t quite keep up with CD quality, aptX HD gets extremely close to the mark with a little processing creativity. Both codecs fall short in the highest frequencies a human could potentially hear, but the vast majority of people can’t hear sounds over 18kHz anyway.
Audio connoisseurs will probably gravitate towards aptX and aptX HD, as it provides almost CD-quality dynamic range.
However, that software processing can’t fix noise issues in high notes. For best results you should listen at volumes below 90dB. Any higher and you’ll hear noise above 1kHz.
Before you ask: no, that’s not very quiet.
Good enough for most people, but not for everyone
Bluetooth headphones and earphones like the Apple AirPods may be good enough for most people, but it’s not good enough for everyone, and that’s a problem. While the benefits of high-bitrate music are largely academic, some flaws with Bluetooth audio prevent it from replacing the 3.5mm TRRS plug in all contexts. It’s a more expensive, less effective solution.
If you’re looking for commuting headphones, they’re great. Music lovers listening in a quiet environment will want something with a wire. Not only will it be cheaper, but it’ll work better too.

The father-daughter dance is often a tearjerker at any wedding, but for one Utah bride, the dance took on an achingly beautiful, bittersweet tone when her five older brothers stepped in to dance with their sister since their father, who had passed away, could not.
Standing on the dance floor in her bridal gown, Kaley West Young was overwhelmed with emotion when her brothers explained how the father-daughter dance was going to work.
Each brother — Kevin, Dustin, Danny, Derek and Kasey — was going to dance with Kaley to Michael Bolton’s song, “Fathers and Daughters,” during the reception on Sept. 22.
The brothers edited clips of home video that Kaley’s dad had taken over the years, so that her father’s voicespoke over the music as the song played.

The moment was beautiful, bringing the room to tears as they listened to the voice of David Jean West, who died suddenly in March 2015, telling Kaley how much he loved her.
WJLA-TV caught up with the new bride who was on her honeymoon in Italy to speak with her about the unforgettable experience.
“I was completely in shock,” Kaley said. “I know people joke about having an out-of-body experience but that is what it truly was being in the middle of the ballroom and surrounded by my family, and my husband’s family, and our friends and people we care about with my brothers stepping up. It was an incredible moment.”
The video clip reached the eyes and ears of Michael Bolton himself, who said he was “humbled and honored,” that the West family would use his song for such a meaningful, incredible moment.

Kaley told WJLA that the video isn’t just about her, but reaches a larger audience of people who have experienced love and loss.
“This video isn’t about me or my family; it’s about the most important thing in life which is our loved ones,” she said.
“Every single person experiences loss, or will experience loss, in those moments can be deep sorrow and despair.

“However, I want it to be a reminder that you are never alone. Love transcends beyond the physical body and whoever is going through a great loss, no matter what it may be, you are never alone and you are loved.”

Be careful of what you say around your Echo devices.
A Portland woman was shocked to discover that Echo recorded and sent audio of a private conversation to one of their contacts without their knowledge, according to KIRO 7.
The woman, who is only identified as Danielle, said her family had installed the popular voice-activated speakers throughout their home.
It wasn't until a random contact called to let them know that he'd received a call from Alexa that they realized their device had mistakenly transmitted a private conversation.

A Portland woman was shocked to discover that Echo recorded and sent audio of a private conversation to one of their contacts without their knowledge
The contact, who was one of her husband's work employees, told the woman to 'unplug your Alexa devices right now. You're being hacked', KIRO noted.
'We unplugged all of them and he proceeded to tell us that he had received audio files of recordings from inside our house,' Danielle said.
'...I felt invaded. Immediately I said, "I'm never plugging that device in again, because I can't trust it"', she added.
Thankfully, the recorded conversation was only about hardware floors, but the incident has still managed to spark fears of Alexa spying on its users.
