If it feels like you\u2019ve spent your whole life looking for the perfect Bluetooth running headphones, you can call off the search\u2014Trekz Titanium, the entry level offering from the Aftershokz range of bone conducting wireless headphones, is the full audio package for those with active lifestyles.\r\n\r\nThe principle concerns for runners seeking Bluetooth headphones are going to be the overall fit and the battery life. The Trekz Titanium wore comfortably with no bounce or travel as I put them through their paces over road and trail runs\u2014and the battery wasn\u2019t troubled by a full week of marathon training, offering me access to music and podcasts for well over the stated six hours (I clocked up over 75km, and 7 hours, of running and never emptied the Titanium\u2019s rechargeable lithium ion cells).\r\n\r\nBone conducting technology may be a worry to those who\u2019ve never tried it as it is so different to the in ear or over ear headphones which are the norm. The sound from the headphones is transmitted through vibrations in your jaw. This is jarring at first if you use the headphones at high volume, but it quickly became my new normal as I listened to podcasts while pounding the pavements. The placement of the headphones, worn just in front of and looping over the ear, actually contributes to the comfortable fit as they gently clamp into place on the head.\r\n\r\nSpoken word audio comes through as crisp as if the presenters were running with you and music playback is admirable too. There are certainly going to be better headphones for audiophiles at this \u00a399 price point, but those headphones won\u2019t be offering the light weight and comfort afforded by the Trekz and that\u2019s a trade off worth considering if you\u2019re buying these headphones for sport.\r\n\r\nA big benefit of bone conduction is that the listener\u2019s ears remain open to the world, and this makes the Trekz Titanium a good option for the safety conscious. Increasingly bone conduction is supported by race and event organisers who otherwise ban other types of headphones, and that\u2019s a selling point that Aftershokz is keen to get across to buyers.\r\n\r\nIn use, the headphones connected quickly to my phone and the signal stayed strong once I\u2019d found the optimal placement of my phone in relation to the headphones (I wear my phone with its Bluetooth antenna pointing towards the right hand side of my body, and I\u2019ve not experienced drop out). Some have argued that at this price point the alignment of the phone and the headset shouldn\u2019t be quite so critical, and that\u2019s a fair point. This minor flaw is probably the main direction through which Aftershokz can make improvements (although increasing battery life will always be a popular win).\r\n\r\nUltimately if sound quality for musical playback is what you need you will want to look elsewhere, but if you\u2019re looking for comfortable, durable sports headphones the Aftershokz Trekz Titanium (\u00a399 from approved stockists) should be near the top of your list.
